Has anybody found out anything else on this problem? Asus wrote me back with a bunch of garbage that has nothing to do with my problem so I'm giving up on asking them for now.

i´ve bought a p4c800 asus deluxe and i can´t overclock it neither manual settings or by %.

I think my P4C800-E Deluxe motherboard is a revision 2 and it crashed on x-mas day and since hasnt worked. I asked around on chat rooms and they said it was either my mobo or my cpu. I thought it was my cpu that had blown from overvolting in the past and so i rma'd it and the replacement arrived yesterday. I tried the new cpu and i still get the "system failed cpu test" vocal msg without any other signs of life other than spinning fans and case LED's coming on. i.e. no beeps, nothing on screen.

It is definitely the motherboard that is the problem as I have tried different gfx cards, replaced the cpu, different ram, removed all non-essential hardware, took mobo out of the case, reset cmos using jumper, etc. And still to no effect. The strange thing is, my friend came round the day before, with his shuttle pc, and his motherboard also failed to post. It is really strange and I think some undetected virus may have been involved, damaging our BIOS chips in some way.

But anyways back to the mobo, I dont think anything necessarily got crushed as I have been using a prometeia mach2 cooling system which means that I had to remove the hsf brackets from the motherboard as soon as i bought it. I thought that maybe condensation was the problem, despite using looooads of that black 'sealie string' which made any chance of condensation absolutely minimal.

However when i looked on the back of the motherboard around where the cpu is, there is a small resistor, which, if i look at it very closely under a magnifying glass, might be slightly damaged, but there is some strange green-like-powder that seems to have appeared in and around the joint where the bottom of it and the surface of the motherboard meets. I'm not sure if this is the protective green layer burned, or if it is moss from condensation?! Or maybe what was inside the resistor leaked out if it was damaged. It is so small I cannot see if it has been damaged or not. Also its colour is lighter than all the other resistors on the board, if that has any significance.

That is all i can think of atm, I'll probably rma the mobo but its such a bitch to pack it all and send it, as well as the cost in weight . It is not my fault its gone faulty, ASUS or the company who sold it to me should pay for its return tbh. Its been 23 days since my pc has been out of operation and I'm not happy

I RMA'd my board and ASUS reportedly "analyzed" it. I'm not sure what they really did, but they are sending me a supposedly new board. I talked to their customer service and technical support to try and find out what they say was wrong with my board, but no one would tell me anything. Basically, the people I talked to did everything they could to keep from admitting the problem truly exists. The customer support guy told me that I can just keep RMA'ing boards. Yeah, real helpful. The tech guy basically told me he would lose his job if he admitted the problem exists, but he did say that not every board has the problem, that it's "hit and miss". Again, that doesn't really solve the problem.

This seems like a bunch of crap to me. Obviously, from this forum alone, we know this is a recurring problem and that ASUS should do something about it.

That's odd. I had this very same problem with my P4C800-E Deluxe and none of the suggestions worked. After about 2 hours of messing around with stuff, I made a shocking discovery. The one small, square power plug with 4 sockets on it was left unplugged. Geez, how could I be so sloppy after all these years of building PCs?!

Anyway, I plugged in the plug (located directly next to the first memory slot) and the "system fail cpu test" warning FINALLY went away! I'm flying now.

Recheck your plugs and cables going to your motherboard, y'all! That might solve the problem.

Hi guys, I've been watching this forum since I first found that my ASUS mobo has been afflicted with the "System Failure CPU Test" wail around July last year. I've never been daring enough to interfere with the mobo, other than removing the mobo and all peripherals, cards and connectors, and releasing the clamps on the CPU heatsink. I initially determined that there was a problem with the AGP 8X from ASUS, and that to correct the problem was to remove all power - physically disconnect the power supply from the box, and let it sit for about 30 mins. This also meant disconnecting the power from the Graphics screen at the same time. I worked out that there is some sort of latching between the graphics screen and the AGP adapter card, that required that both of these needed to have any power absent until the capacitors had completely discharged (about 30 mins). Initially, this problem was the main one causing the woman to wail. Then I managed to get the system up about 3 out of 5 times, and when it did come up, I'd leave it up for about a week or so. I could restart but if I did a shutdown, the likelyhood of coming up again diminished.
Then, after about 5 weeks of this behaviour, the mobo decided to fail constantly. Reading the posts above, I guessed that the "solder under pressure turns to fluid" problem had probably hit me. I powered off the box and archived the machine in the spare room to collect dust.
Came November, I had a health problem and had to work from home, but my laptop was dying with disk failures and I needed another machine while the laptop was being repaired. I brought out the ASUS box, tried to bring it up - usual wailing, but in desperation, removed mobo, loosened heat sink latches, and removed all cards and connectors. Left mobo lying flat for 24 hours with heatsink loosened, and then put it all back together - without any configuration changes. Booted twice, the first failed with system failure cpu test - and my heart sank, second boot a few minutes later and she came up. I kept it running until I received my laptop back and restored the hard drive, then gambled on a reboot of the ASUS.
If I said that the box is back in the spare room, I think you can work out just what I think of this piece of work from ASUS.

why dont you send it back to them



jp

better yet, donate it and send it to me!!!!

My experience.

P4C800 Deluxe
P4 3.0 C
2x512 Ocz 4000 gold
Antec 550 W
9800 Pro+ Tec
Prometeia Mach 2

After having my Pc working 100% stable, suddenly one day Freezed,after restart never boot again.
Our lady saying "System Fail Cpu Test" No video signal etc.

My solution was just re assembly the Mach 2 evaporator (re-install the heatstink for air people)
After do that pc bott again
BUT...If i tell you the true,my system is not the same.
Now is not 100% stable, i cant do some benchmarks,and before with the same settings i did them
succesfully many times.

Thanks everybody for all the info on this "issue."

I recently bought a P4C800-E deluxe with a Pentium 4 2.8 GHz Prescott processor. I got the infamous "system fail cpu test" error, and after some reading discovered I needed to upgrade the BIOS before I could use the Prescott. I borrowed a P4 2.4 GHz Northwood from my girlfriend's computer, and still got the error. This thread pointed me towards the solder issue, but upon inspecting my mobo, I discovered it is version 2.00 and does not have the solder pads anymore. Reading deeper into this thread led me to find that my old ATX power supply did not have the 4-prong 12V connector. I bought a new one, but I am STILL getting the error!

I am hoping someone here has a solution for me so I can get my system up and running (without contacting ASUS or doing an RMA).

my stats:
Kingston 512 MB KVR400X64C3A/512
Asus Radeon 9600 XT/TVD 128MB 8X (also tried older Radeon card)
Western Digital ATA133 120 GB HD
Antec 350 W power supply

Brian,

Double check your hardware connections and make sure all the power supply cables are hooked up to the motherboard. When I was getting this error, everything was as it should'a been (at least that's what I thought) until I finally found the source of the problem. I had accidentally overlooked a 4-pronged power cable that was supposed to be plugged into the motherboard. Once I plugged in that cable, the error message went away and it's been smooth sailing since. Good luck!

I am having the same problem but mine has to do with updating the bios. I tried to update it from version 1011 to the latest 1016. I backed up my original bios to a file, then I ran afudos (the new one like it says on their website). Then i get something along the lines of (sorry for not being specific)
Memory Mismatch: 0x0000FF Bios update failed

I then knew I had a problem so I tried to restore the backup I had made. I got the exact same error, so at this point I knew I was screwed. I crossed my fingers and hit reboot - SYSTEM FAILED CPU CHECK.

I am not sure what to do at this point. I am using
Intel 3.0cGhz
P4C800-E Deluxe
4x512 DDR 400 Kingston
9800 Radeon pro AIW
2x120 Seagate SATA HD

Everything was fine until I pooched this update. Can I use the Asus CD that came with my MB to do this as it says on their site:
CrashFree BIOS 2~
Whenever BIOS gets corrupted, ASUS CrashFree BIOS 2 allows users to reboot the computer and perform an smart auto-recovery procedure through the motherboard support CD.

I can't see how this will fix it (I hope it does) but it is worth a shot, but if it isn't POSTing, I can't see it doing this. Also if it is trying to recover, or has recovered an old version of the bios, could it potentially not recognize my newish CPU, hence the POST message?
I have also taken out the battery, and am going to switch the jumper to reset the bios, i just needed to get online to figure out where to start.

I have had no problems since I put it together back in November (other than the occasional stupid OS crash) so any help on this would be great.
Also since I haven't modified my MB in anyway, am I still covered by the Asus warranty?

Does anybody used the wi-fi port on the p4c 800, if so how is it.

I had that annoying "System failed CPU test" ..

Solution: http://bq.fi/20040505power.jpg

This SHOULD be connected to the mobo! :p

I wish my problem was as easy as power.

I bought another p4c 800-e DLX MB and my computer is fine again.

I need to know if I should send my other p4c800-e MB back to Asus to get it repaired or if their is something I can do to fix it.

The problem is the bios got flashed, but the flash failed, then I tried to recover the old bios and that failed. When I rebooted I got the SYSTEM FAILED CPU CHECK.
So my problem has to do with corrupted firmware on the MB (which I corrupted by trying to use the new AFUDOS.exe to flash my MB).
I removed the battery on the MB and moved the pins to clear the bios, but this didn't help (unless it reset my MB's firmware so far back that it doesn't recognize a p4 3.0c processor.

Worst case scenario is I RMA this board back, and get it fixed to sell on eBay as my new board is installed and updated perfectly. I just want to know if perhaps I put in an older celeron processor into this MB, if it will work, I just want to avoid any extra work that may not be helpful anyway (like building a barebones PC to see if the MB is working still)

Thanks

To solve this annoying problem, you must have a higher Power Supply Unit (PSU)

If you are not sure, I will give you my explain of what happened:

230W PSU
Using 230w PSU gave me the voice error. It was annoying and it got me wondering.
I checked my settings, etc. So I changed the PSU.

400W PSU
It was a success!
Reason is because not enough power pushing the circuit. More power was needed for high performance PC

Specification:
AMD Athlon XP 3200+ (Locked, trying to unlocking this CPU)
ASUS A7N8X-E Deluxe
MSI FX5700LE TD128
HDD : 120G + 80G + 130G
Innovatek Water Cooling (1 Massive Radiator, 1 Small Radiator, 2 Reservoir, 120mm Fan)

ASUS RMA'd my mobo and the new one works fine!

I have a similar problem althou it doesnt have any effect that i have noticed exept when i get a cpu-usage 100% and the voice steps in with our belowed "System Fail Cpu Test". Its quite annoying and i have tried most the things youre talking about. Isnt there just a way to shut the voice off? My mobo is ASUS A7N8X-E

/Nils Österling

No, there's no setting to disable the voice of "System Failed Cpu Test", and "System Failed RAM Test".

I'm not sure about the P4C800 Deluxe, but on my P4C800-E Deluxe, I can disable the voice warnings in the BIOS. Go into your BIOS or read your mobo's manual about the BIOS settings and look for the option to disable the voice warnings. It should be in there.
