joe jones:

I was using the 1006 bios and still had this problem apparently, so I think no.

did i say 1006 bios?

i meant 1007 and 1008 beta, you can get them on the germn site but i havent used them as yet, my cd rom is busted and i dont have live update installed on my pc.

my mothers computer weny belly up the other week. taking out the cdrom, cdrw, mobo, cpu, ram and power supply. so i thought i,d get the ASUS A7N266-VM with a 1800xp+ and 256 ddr 266 stick off ram. all tihs inside a new case with a liteon cdrw. i put it all together using her hard drive monitor keyboard floppy and mouse. it booted to win 98 from the old install which was based on a via chipset. i backed up every thing she needed then did a format and intalled win 98. but couldn't get some of the nforce drivers working properly so i tried win me and was having all sorts of problems with random errors and blue screens usually when multitasking. so i tried win xp pro and now it throws up all sorts of stop errors during install. so i can't get xp running on it. (a few of the errors are 0x000000c2 and 0x000000de) ive looked them up on microsofts site but not sure what route to take.
does any of you guys have any suggestions Hard drive, ram, or power maybe? i don't know.

thanks for any help

This is a great thread, I have spent the last hour reading through it. But I think I have a new problem for ya. I have built 4 systems with the exact same config. An ASUS A7n266-VM/AA, 2400+ AMD XP 256MB Crucial RAM, 40Gig Maxtor, and XP Pro. On the latest machine I installed XP Home and noticed that the cpu seems to be thrashing, the Task Manager says that the system process is using 99%of the CPU. I tried a XP 2100+ and have the same problem. I also tried to reintall the OS from scratch and the did a bios flash. Nothing seemed to work. Also none of the USB Ports work.

Any Ideas???

@ trav

Thats very interedting because i have the vm and i get exactly the same, its like at times my whole system is on hyper mode, the cursor blicks about 10 x faster , folders open faster everything is speeded up, but this only happens after a while of using, i thought it might be a faulty CPU or overheating , but now tht you get the same thing i dunno, i have changed HD, checked memory, changed video card, so maybe its this mobo, no idea how to fix though.

Hi all,

can anyone tell me why every time i want to check my email i have to enter all the settings from scratch? after entering them i apply and save but when i boot up again they are all changed.

My system is ASUS A7N266-VM Mobo, AMD 2400+xp, 512mb PC2100, Deskstar 80 gig HDD, generic 3.5 floppy, 54x CD -Rom(not sure of make) and i'm running windows xp.

oh and also i loaded/installed Grand Theft Auto Vice City but when i try to run the game it seems to take for ever to load the it freezes......any ideas?????

I have a brand new PC, ASUS A7N266-VM, AlthonXP 2200+, 256mb DDR, Inno3D GeForceFX 5200, 20 Gb Seagate HDD and a 52x CD-ROm drive. I got it from the shop and it came with an eval copy of XP Pro installed. When I booted my own XP Pro from the CD and I reformated the HDD (via XP's Setup), the monitor just went blank (after reaching 20% or so, i left for a while to check on another PC). Now my PC won't power up. The HDD LED lights up but that's about it.

My bad, I meant the motherboard LED.

thats strange.

try reseating the cmos battery, thats means taking the silver battery in the mobo out ffor about 1 min then back in again. other than that make sure everything is seated in tightly and you might even want to take your stuff out and set it up outside the case, cases are know for shorting, next to that it could be a faulty PSU.

this is aimed at the post directly above

I changed the PSU then the thing worked fine again.

Then after running a game (Praetorians), it died again after a few minutes of gameplay.

I had the PSU replaced for the SECOND time today and the thing was running fine, I even had it running for over an hour straight. Then when my brother loads a game, it just dies!

What are your CPU temps? It may be running too hot. If not, your PSU may be on its last legs.

Replace the power supply with a quality one before you smoke the whole system. Something like the Antec 430W or bigger should do fine.

I'm running mine reliably at 2319 MHz using a 200 watt Enhance PSU

If it craps out after a period of intense game play then it's most likely an overheat problem... either the CPU or the Northbridge (the latter gets VERY hot... I've taped a small fan on mine)

Think about where the heat has to come from....more heat equals more power supply takes power to produce heat....when loading a game..both CD rom and HD are loaded....

@Robert Shores

I'm not exactly sure at what you're implying here. A PSU only needs to be as large as the equipment you're trying to run. If you're trying to run the latest P4 (which requires about 80w now), the latest video accelerator (and Im talking about the ones with the 12v power plug i.e. Radeon 9500, 9700, 9800; Nvidia FX5600, FX5900), the fastest DDR Ram, multiple HDs in RAID, multiple optical drives etc., that would warrant the 430w PSU. You don't purchase a LARGER watt PSU based on how hot the one you currently have is getting.

Now, going back to Frank's case, he's running an XP2200+ prossie (which requires a MAX of 68w, typical is 62w though), a FX5200 (which does not need the additional power load), one 20Gb HD and one optical drive. This does not warrant a 430w PSU....perhaps a 250w to be safe but 430w?? (Maybe if he's futureproofing. ;) )

However, this doesn't mean that his current PSU is not the culprit. Sometimes cheap PSUs generate less power than its rated for and other times cheap PSUs generate its rated power but as it heats up, the rail voltage outputs diminish. Good PSUs (even the 200w-300w ones ;)) have larger heatsinks/fans inside to avoid this.

Frank, this could explain why your system dies after attempting to run a game for more than a few minutes. But I would first check your CPU temp and like Milt said, perhaps your NB.

>> Franz Co
Mike.... Excellent post! Thanks for that

Here's a link to a good guide about PSUs and what the different CPUs and components draw...

As I said in the above post, my A7N266-VM is running rock solid stable at 2319 MHz with a grossly overclocked XP 1700+, single 256 meg of DDR, 1 20 Gig HD and 1 CDRW on a 200 watt Enhance PSU

You don't NEED 430 watts to drive this mobo. Full Stop.
But it won't hurt anything but your wallet to try it.

Hey guys....I'm just trying to help out here by adding my two cents worth...I'm an electrical engineer by computers for a hobby....I'm not saying you can't get one of these to work with less than a 430W power supply....I've tried everything from 180W to 550W. It' s a function of how many things are on at the same time drawing current. Most people don't list everything they have connected.....does he have a mod case with lights.....extra case fanns....5400rpm or 7200rpm drive..256, 512....1gig of ram....many times it's the 12v supply that won't keep up.....and sometimes it's the voltage regulation on cheap power supplies that make it crash..even when they are rated for 500W. It's funny how many problems are solveed with a quality power supply. He can keep jerking around with a cheap power supply if that floats his boat. I guess some people hate to spend more for a power supply than they spent for the motherboard.....they are the ones that blame the motherboard when they have problems.

I can agree with some of what you're saying... many times people neglect to give ANY details of what all they have in that there box.

But, as an electrical engineer, you of all people should realize that the 'surge current' required to spin up ALL the drives (HDs CDRWs, CD-ROMs etc.) at start up is that 'last straw' that can push a marginal PSU just over the edge.
Because your CPU, as well as all those drives rely on that 12v 'rail'.

But Frank has already said that he can play a game for an hour BEFORE it crashes.

That screams 'TOO HOT' at me.

What's it do for you???
