Prime95 exception C0000005

sunten · 2005-01-12, 10:51

Hi all

my specs:
Gigabyte GA-7VRXP (VIA KT333 chipset)
Athlon XP 1900
Geforce4 Ti4200 on 66.93 driver
On-board Creative PCI 128 (CT5800)
60GB HDD
256MB PC2100 DDR

I have been debugging my system lately due to all the BSODs I have been getting while playing games. The BSODs varied from Stop 0xA, 7E, 8E, D1, 50 but after some video/audio/VIA driver cleaning/reinstalling, I have gotten only one kind remaining: D1 and it points to sbpci.sys (sound driver). I have 3 sticks of RAM and after some memtest86 runs, I just found the stick that doesn't give me any blue screen for now.

However, when I run Prime95 torture test, it either freezes (Small FFT) or gets the C0000005 exception (Large FFT and blend test) and closed by windows. The exception address is consistent and is always around 0x569AE0. I also get the C0000005 exception for other programs such as winamp and WMP.

Once I did manage to run Prime95 without the exception. The Large FFT shows illegal sum out errors like 10 seconds after I started the test, accumulates to 100 and stops. Same for the blend test.

Given my case, can someone tell me which hardware is causing the failure and what I can do to pinpoint it? Could it be the RAM still even tho memtest86 didn't catch any errors? my cpu cache? sound card?

Any help appreciated. Thanks.

PS: Games still crash, but no blue screens.

it could be a sound card is everyhting proprely cooled aka have u ever cleared the dust out of the expensive air filters we call computers... (picked that one up from here ;) thanks to who ever coined it) but it could be over heating try remoeving ur sound card also and uninstall drivers and then try to run p95...

My comp is not overheating. I left the case open and I did clean the dust of my CPU and GPU fan quite recently. Only programs that play sound tend to crash. But I don't understand why the soundcard can make p95 crash as well. I will try uninstalling the sound card and run p95. Should I run it in safe mode too?
Thanks

sound cards can do strange things.... but it could be a poorly written drive or even a bad vid driver also could u give some software specs like what version of windows/ service pack....

I am running Win XP, didn't install any SP.

I uninstalled the soundcard as you suggested and ran p95 in safe mode. There are a few things listed under "Sound and Audio devices" such as Audio Codecs, Legacy Audio Drivers, Standard Game Port, etc... I first uninstalled my Creative 128 PCI. P95 first gave me 100 SUM OUT errors for the Large FFT test, then crashed with that C0000005 exception when I ran the same test again.

(Still in safe mode) Then, I uninstalled the MPU 401 Compatible MIDI Device under Sound and Audio devices. This time P95 can run a few times more before that same exception. Large FFT gave me 100 SUM OUT. Same for blend test. However, the small FFT always gives me a blue screen. They are Stop 0xA and 0xD1 pointing at atapi.sys (my CD ROM driver). I am confused coz nothing was using the CDROM at that time.

hmm u got me there if it was pointing to sound card then removeign sound card and drivers would have solved it.... what type of internet connction do you have if its high speed it would be in your bext intrests to update windows....

I decided to reformat and reinstall windows xp from fresh. Just when it finishes formatting and about to install windows, i get a blue screen stop 0xA IRQL LESS THAN OR EQUAL...... so it is definitely a hardware instead of software/drivers problem right?

Beware!

You may be correct, but it may yet be a drivers problem. I had some similar behaviour with a Win 2003 Server box. The machine failed to reboot after a power loss, it kept blue screening partway through booting. It came up in the recovery console and in safe mode but there was nothing obviously wrong, nothing in the system logs, etc. Ran a disk check, and there had been corruption. Rather than spend a lot of time diagnosing in detail, I re-installed, opting to keep the previous install in place so that I wouldn't lose user files.

The installation ran fine until it rebooted, when it blue screened again. This time, however, there was a good audit trail which pointed unambiguously at the sound card. A quick rummage through MS's knowledge base found the exact error: the stock OS couldn't drive the sound card. Recommendation is to remove the card, install the OS, install the manufacturer's driver and then add the card. As I didn't need or want sound on that box, I carried out only the first of the steps.

As the initial install had been successful and the machine had been running well for months, I can only assume that either the bug in question only showed itself under certain circumstances, or that the sound card had not been seated properly and had never worked. I'd never tried using it, so can't really tell.

In your case, it may be worth while investigating microsoft.com and Google, using chunks of your error message as search terms. It helped me.

unfortunatly last night something evil i found of windows xp evilnesses well what it is there is a file window/system32/config/system this holds all system settings and what not and give unfortunaty if it gets to big it causes system toerror and not be able to restart now heres the super evil part i fixed it but xp works limited i mean all drivers needed to be reinstalled and what not i have 90 gigs of info split between 2 hds so i need to format the first drive that is super evil.......

Since my soundcard is on-board, I can disable it in the BIOS. I did that and p95 still crashes with the c0000005 exception. So does that mean it is not my soundcard that is faulty? Really need help on this as I am totally confused! Thanks!
