Hello, and thanks for reading this post. I'm having a serious computer problem, that I am hoping to get some advice on. First off, let me give my system specs.

Gigabyte GA-7vaxp motherboard
AMD Athalon XP 2400 (not overclocked)
Antec Case w/ 400watt powersupply
Radeon 7600 video card
Pinnacle Studio Deluxe video capture card W/
Pinnacle PCITV Pro TV Tuner card
Microsoft Internet Pro PS2/USB keyboard
Microsoft USB Optical Trackball
HP 100i DVD+RW drive
Sony DW-U18A DVD +/- R/RW Drive
generic floppy drive
6 hdd's
1) WD1200BB-oocaa0 120GB hdd
2) Diamond Max Plus 9 6Y120L0041001 120GBhdd
3) Diamond Max Plus 9 6Y160P0041201 160GBhdd
4) & 5) Diamond Max 9 6Y250P0062211 250GBhdd's (2x)
6)Seagate Barracuda ST3400832A 400GB hdd

My first symptoms started several weeks ago when the system suddenly crashed for no apparent reason, and I got an NTldr is missing error (which I thought had been solved, perhaps it was, but I am including this info in case it is relevent) I fixed that error by following the advice in several posts to this forum for others. I then rapidly preceded to get my system ready for a total re-install from scratch, just as a precaution. on Friday 12/17, I took the system down/ removed all cards, and reseated them, also as a precaution. as well as reseating all the cards, I double checked all of the connections to the motherboard, and to the various drives. And got ready for what I hoped would be a seamless re-install. I installed Windows XP Pro, and everything went fine with the install itself, the problems started when I began installing drivers. I started with the Gigabyte drivers, and then restarted. uh oh trouble in paradise. System would not come up... says "keyboard error, keyboard not installed, or not found" during post. Oops, keyboard plug must be loose... NOPE!?!? restart... everythings fine <shrug>but not windows hangs at boot.... before any screens appear past POST. OK, maybe I instaled the wrong drivers... Yeap, I installed the wroing drivers for the Promise IDE 20276 ATA 133 controller built onto the MB... I installed the RAID drivers accidentally. Actually, *I* didn't... the gigabyte disk installs those by default. If you want the ATA drivers, you have to find the proper dir and select the setup file for the specific drivers you want. OK... I re-installed again, this time I got the proper drivers, so I went on to add in the Radeon drivers, and everythings fine for now. Left things alone, and sometime during the night, the system crashed. a restart, only now I'm again on a blank screen with no mouse movement, no keyboard, and no idea even that it crashed. I at first assumed that the powersaver had kicked in. so I restarted, and again got that blasted "keyboard no found" error, 4 times in a row. when it finaly went away, windows again hung on restartI get through post all the way to where it checks for bootable CD's, and then a blank screen that sits there for 15 minutes until I get tired of waiting for the "welcome to Windows" screen to appear. Again I decide to re-install, and before installing any drivers, I get online and get all the latest drivers for everything except the kB and trackball. So far no trouble with installing drivers. I run Windows update after installing Netscape, but *do not* install any updates. By this time, it is Sunday mid-morning, and my system begins spontaniously restarting every 5 minutes (give or take). The morning is spent trying to keep windows up long enough to disable windows auto-restart feature. when that is finally done, I reboot a few times when I start getting an error that goes:
IRQL_NOT_LESS_OR_EQUAL Stop: 0x0000000A (OXB2533FFC, 0X000000FF, 0X00000000, 0X804F00A9) i read very carefully, and no driver was mentioned. I got online (on another computer) and researched what that error was (again at this site) and found that it was probably a hardware error involing drivers for one of my devices. I went and again downlaoded all the drivers, making absolutely sure that I was grabbing all the right drivers, and that they were the newst ones available from the manufacturer. Put them on a USB flash card hoping to be able to put them onto my system that way (60MB's of drivers don't fit well on floppy's, and this system does not have a cd-burner.

Now is when the fun *really* begins I go back to the computer with all the problems to reboot, and my system has spontaniously tried to start itself up (no joke!!) There is noone else in the house to turn the system on, and I am *positive* that I turned it off and not rebooted. I am also positive that I turned it completely off, because I watched it shut down... completely. only I'm not staring at a Windows welcome screen, or a login screen. I'm staring at a blank screen. so I restart, and the monitor does not even turn on for POST. I hear all of the HDD's power up. I hear all the fans on the system come on. and I have varified that the fan on the CPU starts up. I hear the DVD drives power up. I see the little red light by ram chips (a feature on the Gigabyte MB's that lets you know it is unsafe to remove RAM from the system), the light on the DVD drives come on, the light on the optical trackball is on, and the led's on the front of the computer come on, BUT the three lights on the keyboard do not flash. The power light on the front of the monitor does change it's flashing speed, but the monitor does not come on. Keep in mind for the rest of my desciption that none of this changes no matter what I've tried except for oine thing that I will describe when the time comes. I immediately begin trouble shooting... I started by restarting 5 times to be sure. no change. I then started double checking all the various connections. HDD's, DVD Drives, fans, reseated all cards again, reseated the RAMdouble checked the power connections, as well as the audio connections, and all those connections at the front of the MB. no change. I tried changing the keyboard to see if the keyboard was bad (knowing that something else had to be wrong as well) but hoping that with all power to all the peripherals except keyboard and monitor that it was my monitor, and therefore I could get to windows, and type in my password, and know all I had to do was buy a cheap monitor until I could afford to get a nice 21'inch to replace the one I have. nope, keyboard light *do* (and here is that slight change I mentioned) light up as I plug the keyboard into the PS2 outlet, *however* the keyboiard lights still do *not* light up when I restart) other than that... no change. I tried unplugging all HDD's and DVD drives except the first one. No change other than the other drive obvioulsy now not powering up. I then pulled out the two pinnacle cards, leaving all the hdd's and DVD drives unplugged) no change. I then changed the Radeon video card to a Chaintech GeForce4 Titanium 4200-8x video card. No change. I then sat down and contemplated crying before coming in here to type this up. No I did not cry, and yes, I am trying to be somewhat humorous, so that I'm not screaming and curing every other word. on the two responces, I hope this one is the better.

Now that you've read this book on my travails, does anyone have any suggestions on what could be the cause? thanks for replies, wether thay are helpful or not.

No, I can't boot from a floppy, because AFAIK I'm not even getting *to* POST, let alone passing a POST test. of course, I could be POST'ing, and just not seeing it. what's confusing, is that I've verified that each drive (both the HDD's and the DVD's are powering up. I've done this by attaching each drive to the hdd0 position as the only drive on the system, and listening to it as I turn on the computer.... I am truly and completely stumped. it appears to me that my only options for the cause are the MB, the CPU, very unlikely the RAM, and very very unlikely, some strange problem with the powersupply. I'm going to dig up the manual, and see what it says about beep codes... all I hear is a softer than normal single short beep, kinda like the "all-clear" beep I normally hear, axcept softer than usual.

Try a different video card. Preferably a PCI card. I keep an old one laying around just for situations like this. It could be as simple as the video card being poorly seated, or went bad some how.

The fact that you get a single beep tells me that it is passing POST. But the signal isn't getting to the monitor. Could the cable be loose?

hmm... I *think* I might have an old Viper PCI card around somewhereif it's not an ISA card that is. and out of all the old cards I have, it's the only one that might possibly be a PCI card. I have already changed the video card once... to a Chaintech GeForce Titanium 4200- 8x. if that didn't solve the problem, and a PCI card *does* solve it, then I'm returning the board as it's just less than a year old, and the AGP slot should definately be one of the last things to go bad. anyways.. I'll have to try that after work tomorrow. will get back to you tomorrow afternoon to let you know if it worked (or that the Viper card was not PCI. the cable is not loose, as some sort of signal is getting to the4 monitor, because turning the PC on causes the monitor LED to blink at a different rate than it blinks when the PC is off... not to mention, it was the first cable I checked :)

As for the POST test... under normal circumstances, the POST beep is loud enough that I can hear it anywhere in my house. this beep is so soft, the first two times I heard it, I thought I was imagining things. I guess I should mention that I can hear the beep loudly when the case cover is on, and during the re-installs the case cover was off, and it was of course louder than usual, while the beep now is softer than it ever was even with the case cover on. but thanks for the suggestions, and for trying to help Josh.

and while I'm at it... Ioneabee, I forgot to say thanks for your suggestion as well.

I checked out that Diamond viper video card I thought mught be PCI or even ISA. sorry, but it's an AGP 1x card. Which means that I don't have any video cards that are PCI. I will try to ask a family menber if I can borow for a day a card that I put in thier machine a few years back. And I will try pulling out ram sticks one at a time to see if one of them is bad (god help me if both of them are!). Anyone else have any suggestions? I've been saving up (or trying to in this xmas season) to get a new MB combo. I've been trying to set up two systems for daily use.. one for the internet, DVD burning, and graphics re-encoding, and the other for gaming, but it looks like that is on hold. ironically if it's the RAM, that's going to be more expensive to replace than MB/CPU. and I'd *really* hate to replace the MB/CPU prematurely only to find out that I need to get new RAM in order to get a single system up and running.

I would try a different stick of ram, if you have 2 you can pull one try to start and if it won't boot replace it with the other. Is the computer beeping at you when you turn it on?

OK, here is the latest tests I've run...
first off, I removed all cards, drives etc leaving ONLY a power supply, a single ram chip, the gigabyte ga-7vaxp MB a 2400+ AMD Athalon XP processor, and a GeForce4 4200 video card, a keyboard and a mouse. Of course the fans attached to the MB and the Processor were left connected :) WOW a big change (NOT!) only a tiny change... the sytem no longer beeps at me at all. no single loud beep that tells me that POST was past. no single soft beep that was supposed to tell me who knows what, and certainly the monitor doesn't change status. This monitor has been verified to work on another system already. I then swapped out the single ram chip for the other ram chip. no change again. I then performed two seperate tests... first I took a verified PS that I guarantteed to work with another system, and swapped it out no change from the last time. I then swapped the PS in the gigabyte system into another system (the same one that I took the verified PS out of, and it booted up fine.... so I have verified that this is not a PS issue. I have also verified tha this is not a monitor issue, nor is it a video card issue. this leaves a few options, or combination of options

1) the MB is bad.
I doubt this, because when plugged in HDD's and optical drives power up... as does the little LED light near the RAM chips that gives you warning not to try to mess with the ramchip, as they are recieving power. also I doubt this because the trackball is getting power to light up, and get brighter when I roll the ball around, and the keyboard lights up momentarily when I plug it into the PS2 port. but does not light up when I turn on the computer. if there is something wrong with my logic here, would someone with expert experience please explain what is wrong with it? I'd really like to increase my knowledge of computer repair as a result of this experience.

2) both of the ram chips are bad.
if only one of them were bad, then at one point or another the system would have at least tried to POST. however keep in mind (I prolly didn't mention this before, we ARE talking about kingston memory here. they have a deserved reputation for excellence. though I do suppose anyone could make a defactive batch of memory, and memory could get fried for some reason.

3) the processor is bad I consider this the most likely possibility, and if this is the case, it's actually from my point of view the best alternative because they are fairly cheap to replace, AND I can upgrade teehee

4) any two or even tree of these could have happened... though with the PS being verified as good, and my sytem being run through a surge protector that is "guarantteed up to $75,000 damage in case of failure", I'm not sure how all three could fail at once. though I still suppose anything is possible.

anyone have any ideas on how I can test to see which of these possibilties are the right ones? the other system I've been mentioning is a DFI k6xv3+ with K6-III 450 processor 128MB' ram with the afore mentioned diamond viper v550 video card, a SB 16 Awe gold sound card a single 13GB hard drive, a Mitsumi CDRW and a generic 24x CD-Rom. obviously this is not a power system, it wasn't even a power system when the processor was first bought. I also highly doubt, verging on being totally astonished if any of the parts left that I need to test would work on this MB, or that the processor in this system would work with the Gigabyte MB.

Thanks for any help, but before replying, please make sure that what you are asking is not something I have not already descibed. :)

At this point, my money is on the processor being bad. Too bad you can't swap it out with a barrowed one.

I feel your pain. My friend is having the same problem with his computer. He has a amd3200, and has tried everything you have done so far. If you figure out, please post. As for his computer, we'll keep working on it, if we find any solutions or come up with anything diffrent, we'll be sure to let you know. GOOD LUCK!

Thanks for writing... I'm hedging my bets. Kinda. I am assuming for the moment that this is not a RAM issue. and concentrating on the more likely possibilties that it is either the motherboard or the processor. so I went online last thursday, and bought a Gigabyte GA-7n400 Pro2 motherboard (maxed out the cooling options too) and a 3200+ processor. when those arrive, I am going to load the old processor in the new board, and see if everything works. if not, I'll put the new processor in the new board, (this is going to happen anyways!) and save a bit of money to buy a new 3200 processor, and put it in the old board. I'm going this route as the processor being bad is the most likely possibility.if everything works with old processor and new board, I'll put the old processor aside, and save money to buy a second GA-7n400 Pro2 or maybe even a ga-7nnxp board. either way I'll end up with two running computers.

My reasons for going with the gigabyte boards is the combination of features. Dual Bios, build in sound, built in Lan, built inUSB, built in firewire, built in Promise RAID/ATA 133, etcalthough technically the second computer will not need all that hard drive space... it's going to be a gaming only machine, and will be dual-boot Win98se and WinXPone 120GHB hdd should be all I need really. partition it into 4 partitions... two system paritions, and two Data partitions.

anyways, what I suggest to you, is to either buy a new MB/CPU combo, or if funds are at a premium, take a gamble, and buy a new processor.. OR you could try cannabalising a known working PC, and put the processor from it in the board on the PC that is not working right. If everything works, you know it was the CPU, if not, then it was the MB. Either way you know what needs to be replaced

First, check and double check, just in case, that your monitor cable is firmly plugged in. If the cable has posts to screw them into the monitor and video card, please make sure they are screwed tight. Those posts are there to make sure that the cable stays tight. *If you smell a smoky, ascrid, and/or burning metal smell, immediately turn off the monitor, and do not turn it on again.* In this case, you have a monitor that is going bad, and needs to be replaced. Although it's not highly likely, if you smell anything like the above, it is possible that your monitor could start a fire. Yeah, yeah, yeah, I know it's not the most likely thing in the world, but this has happened to a friend of mine, so better to be safe than sorry. I could be wrong, but I don't think it's the video card causing the monitor to flicker.

Thanks for writing :)

OOps, sorry guys, I completely forgot about this thread. I ended up buying a whole new MB and processor. still never figured out which was bad, because I didn't want to risk either my new processor or MB trying to figure it out. anyways, I also ended up having problems from the first TWO companies I tried to order from.... NEVER EVER EVER buy from NT-Micro... took them a month and a half to send me my product, and THEN then sent it out THE DAY AFTER i canceled the order. Next went to BZBoys, and though the shipping was fast, they sold me a combo unit that included an extremely nice heat-sink fan unit, that unfortunately did not fit on the MB unles you "bent back two capacitors" not being the most dextorous person, I was not willing to try this. After several attempts at e-mailing them, I finally got someone to send me an RMA *and* shipping label. it ended up OK, and I'd ahve to say in the end BZboys took care of me. however it took me so long to get in touch with them, that I tried a third company,, who went above and beyond the call of duty. at every point they were the picture of 110% customer service, they took the MB/heatsink combo I'd ordered from the other company, tried to get their tech to install it, and told me that it was not possible without risking damage, but that it could be done if you are *very very* careful. they then tried another heatsink unit to make sure it would fit for me, *and* gave me a discount. then they gave me free shipping (option was not available at the time, but they were going to start a promotion a month later) for UPS next day air. and I really did recieve my MB/processor and heat sink the day after I ordered it. to end a long story short-ish, I've since placed 7 other orders with, and the one time there was a problem with the order, they took it back, and replaced it no questions asked. I *very highly recommend* this company

so ends my travails in trying to resolve this issue. never did find an answer, and it quite likely is that either or both the CPU and MB were fried

OK Take the Motherboard outside the case and put on a non conductive platform. (cardboardbox etc) check the motherboard for signs of physical damage, (burn spots) bulging Capacitors/ capacitors with White stuff oozing out/crusty stuff ontop of capacitors, broken resistors etc, check IO connectors for damage. Check Plug in boards for damage, check drives for damage, get fresh IDE cables and floppy cables. Check Powersupply for damage. Run the motherboard outside of the case to see if anything changes. if not power off system and check the heatsink for proper seating and also check the CPU for any damage, if possible get another CPU (prefer a boxed CPU with heatsink at lower rating that one you have) Reset the BIOS and see if motherboard boots. Try removing plug in boards 1 at a time, place em in back 1 at a time, try plugging in the boards in different slot.

Most of these things have been done long ago.... I didn't try to run the MB out of the case, but it has been removed and inspected. There were no obvious signs of damage to the MB, and no strange odors. At one time or another, I *have* replaced every single component with another, except for the MB and CPU. I have tried running the computer with nothing installed but a video card, a single hdd, a single ram module, the MB and CPU, and the power supply. the power supply was checked, and verified to be working. The rest of the components have been placed in another system to make sure they all work. At this point (more than a year after the original problem, I am not willing to risk any new processor or MB I bought by checking these components with them. I might look around for an old *really cheap* duron processor at some point, but since I don't really intend to do much with these old components unless I need to put together an el cheapo computer for someone, I'm not going to look too hard. thanks for trying to help though :)

hi there
i have recently had the exact same problem with a ga7vaxp MB. i wont bore you with the list of things i tried to fix it but it never got fxed. so i replaced the MB (and at the same time upgrade graphics card and extra HD, very nice) and everything seemed fine. the new MB is a G7n400S-L. i wanted to keep my processor (2800XP) and skt A motherboards are so cheap that i though why not. like i said everything was fine for two weeks, couldn't play games with my new graphics card but that's on its way back to be replaced, so i know that's a seperate issue. then today, the same thing that happened before happened again. No POST, and no beeps of any kind, at all. tried everything i could think of, no joy.
here's my questions:

1) should a motherboard post with no processor in it?
2) would a messed up processor work in a new MB for a while then screw it up?

I'd be greatful of any help, i know what i'm doing with computers (although i'm no expert) but i can only fix things i've come accross before and fixed.
i've tried everything except a different processor, because i do not have a different processor, nor does anyone i know because they all have silly, expensive pentiums or super 64's.

many thanks in advance

hello i am having a problem with my monitor it was starting normaly now nothing can be veiwed from it. would changing the k8 CPU clock ratio from default to four times 800mhz have anything to do with this?

these are my specs:

Gigabyte GA-K8NXP-SLI motherboard
albertron 7800 GT super high
1 gig of GEIL ram
AMD 3700+
550w power supply
Western Digital 200GB sata2

It setup windows from a boot disk and formated the drive then resets itself and then thats when the monitor showed no more.

any help would be good
