Has anyone had problems with the bios on asus motherboards?
Recently my computer keeps quitting without notice. One minute you are typing and the next you're looking at a black screen. When I reboot I get a message saying that the bios is reporting my processor at the wrong frequency. Then it sends me to system setup. The processor that is highlighted is the right one so I reboot and presto! everything is ok til the next occurance. Maybe an hour or maybe a day. Tech support at asus seems to think it's anything but the motherboard. Namely the memory, powersupply, or the software. This setup worked fine for 6 months. Any bites?

My configuration follows:

MOTHERBOARD: ASUS VIA A7V333-X/L
CPU: AMD 2000+/266 ATHLON XP
MEMORY: KINGSTON HyperX Series 184-pin 512MB
DDR333 (PC2700) 64X64 DDR
Video: ATI A-I-W RADEON 7500 64MB
HARDDRIVE: WESTERN DIGITAL 60 GB 7200 RPM EIDE
POWERSUPPLY: GENERIC 450W
DVD/CDROM: TOSHIBA 16X SD-M1712
OPTICAL: 32X8X40X
FLOPPY: GENERIC 1.44
CASE: MIDTOWER
OP SYSTEM: WINDOWS XP PRO

Hi clewless,
My son's A7V333 used to do similar things--crash requiring a hard reset, and then the post reporter would say things like 'system failed CPU test' or 'system failed due to CPU overclocking.' The problem was intermittent but getting worse. The local computer shop checked the CPU; it was OK. They put in a known good CPU--nada. So in this case it was MB failure.
If you can lay your hands on a good CPU that you can swap in and test, try that first. Otherwise, I suggest RMAing the board.
HTH,

UPDATE THE MOTHERBOARD TO THE BIOS BETA AND IT SHOULD NOT DO THAT BUT MAKE SURE YOU HAVE ALL OF THE MOTHERBOARD SETTINGS TO DEFAULT.

Dunno about clewless or how he fared. My son's computer wouldn't stay on long enough to flash the BIOS.

I recently spent about 30+ hours trying to get past the lovely "System Failed CPU Test" on my new system. Aargghh!! It was super frustrating, and tiresome, but it seems to have paid off. My system is now stable and behaving very well!

Albeit, my ASUS MB is not an A7V333, I'm hoping that my success story can help other PC builders with ASUS MB's having the dreadful "System Failed CPU Test" not booting symptom.

Main components of my new system:
MB - ASUS PC-DL Deluxe (Dual Xeon 533Mhz FSB)
RAM - Corsair TwinX PC-2700 (333 MHz) Matched Pair 2x512 MB
CPU - 2 x Intel Xeon 2.66Ghz 533Mhz FSB Retail with Intel heat-sinks, fans, etc.
PSU - Enermax EG465P-24 460W (Xeon Ready)
HDD - 2 x WD 36GB SATA 10k RPM
VGA - ASUS V9520-TD 128MB DDR 8x AGP GeForce FX-5200
CASE - CaseEdge TS1 Middle Tower (I removed PSU that came with it)

Well here's a brief recap of assembly events, problems and solutions:
- All excited, my components all arrived at my door-step the same day... I'm ready to build.
- Being overly optimistic, I install both DIMM's, CPU's/heat-sinks/fans, & desired jumpers, then mounted MB in case.
- Again, optimistically, I connect both HDD's, FDD, insert AGP card, and connect power to all.
- I connect all case cables (USB, IEEE-1394, game port, audio, front-panel, etc.)
- I hookup my existing peripherals (keyboard, mouse, & monitor).
- Aahhh, now it's time to give a whirl. FYI, it’s never good to connect everything for 1st run. It's better to only install bare minimum to reduce problem variables. I was never much for following rules, hence my repeatedly back-firing optimism.
- Well, all the fans worked and were even blowing in the right direction. No warning lights showed on the MB. But, what's this, a very loud lady starts talking through my speakers. She keeps repeating over and over and over, "System Failed CPU Test, System Failed CPU Test", etc. Hhmmm, okay, that's all my PC was capable of doing. Not even a video signal, hence, not able to view, configure, or update BIOS. Okay, it was back to the real world again. Crappola!
- I searched the internet for info on this "System Failed CPU Test" and, surprisingly to me, found hundreds of articles. I was certain that this problem was plaguing ASUS tech support. I found a few good suggestions, but no real working solutions. Only band-aids and cover-ups.
- Methodically, I checked for the following causes: MB ground/short, excessive PSU connections, disabled (via jumpers) unnecessary MB devices, verified PSU specs to match MB, disconnected front-panel and other unnecessary MB pins.
- Damn! Still no difference. Just the loud looping "System Failed CPU Test"
- I tried reseating the CPU's in their sockets... no change... Then tried booting again and again, and again, and oh wait, it booted to BIOS successfully. Hhmmm, what the hell is going on here? I really truly don't like unpredictable PC behavior. I familiarized myself with the BIOS w/o making any changes. Is it maybe, miraculously, fixed? I restarted the system only to get the "System Failed CPU Test" again. Aargghh!!
- Okay, staying calm, I called ASUS tech support. They supposedly opened a case # for me (still can't inquire about it, because it “doesn't exist on their system yet”. Ahhh boy!!) They suggested trying 1 DIMM vs. the other and likewise with the CPU's. I thought this was a reasonable approach to the trusty elimination process.
- Tried only 1 DIMM, then tried the other. No success here... still "System Failed CPU Test"
- Removed CPU2, then vuala, it booted to BIOS successfully. I restarted and it booted to BIOS again. At this point I'm thinking maybe it's a bad CPU. I would feel very unlucky if this were the case as Intel almost never ships a faulty CPU.
- I installed the CPU in question into the CPU1 slot, leaving the CPU2 slot vacant again. It booted to BIOS successfully. I restarted and it booted to BIOS again. Okay, I'm guessing by this that both CPU's are probably good. Maybe the MB CPU2 socket is faulty.
- I really, really didn’t want to RMA my MB (Not enough beer in fridge for that). So, for kicks, I put the other CPU in the CPU2 socket (keeping CPU1 socket occupied). To no avail, again getting only "System Failed CPU Test".
- I'm not too pleased with the 603/604 heatsink clamp that Intel included with their Xeon CPU's. I seem to recall that even the old 233MHz CPU heatsinks were tighter against the CPU than these. Hhmmm, in desperation, I decide to use 2 pliers to bend the Xeon heatsink clamps so that these bad-boys really push tight against the CPU's. Boy do they fit tight now! Nevertheless, the system hasn't given me a problem since!!!!

I really feel for the ASUS techs. My experience with this problem seemed to be with ASUS, and arguably so, up until this CPU-to-heatsink alteration. I now feel that Intel needs to speak for this issue. I have always been extraordinarily pleased with ASUS's products. They really do build the best in my opinion. However, this issue of "System Failed CPU Test" obviously crosses into the AMD realm as well. Perhaps the ASUS boards are highly sensitive to the CPU manufactures thermal specs. Not a bad idea with today's super-speedy micro(scopic)-chips.

Very briefly, my solution:

Make sure that your heatsink presses firmly against that CPU (never leave out the thermal compound/paste, I highly recommend Arctic Silver or comparable). If you think it could be tighter, maybe try bending (or otherwise altering) heatsink clamps/springs to appropriately increase pressure between heatsink and CPU.


Happy Building

System Failed...

a7v333 experiences:

System Failed due to CPU over-clocking: I took Memory, fan and CPU out, and then put back all. - and it works

Unfortunately after several such operations I broked a small resistor out -> System failed CPU test. I placed it back (with a tape), and works.

So it's recommened to check your MB if it has physical damage.

Thanks for the tips.
