Stange one this - random resets.

[MikeHunt79]

Here's the rig spec:

PSU: Seasonic S12 430W
Motherboard: Abit KT7A RAID (latest BIOS)
CPU: Athlon XP-m underclocked @ 11 x 100 (1.125Vcore)
RAM: 640MB
GFX: ATI Radeon 9200
HD: 250GB IDE Maxtor thing
WIFI: Belkin thing
Soundcard: Audigy 2 (KX drivers)

Now, I've done prime blend and the other CPU stress one for 8 hours each, the temps stay low and I get no errors. But sometimes, out of the blue, the whole machine just resets, then boots up again as if nothing happened. No BSD of death, just instant reset!

It does this weather I'm running Windows XP or Xubuntu. Now, the only thing that I think may be causing this is possibly the GFX card or some bad capacitors on the motherboard... I should be getting another GFX card tomorrow, but does anyone know what causes this and is there some way of fixing it as it's really annoying!

Have you tried running memtest?

 

[Steve2000]

Last time I had this issue was a few years back now, as far as I can remember it was faulty RAM. Try running memtest like the person above said, or just replace the RAM with another set if you have one spare.

Well, I already have tried Prime95 in Blend mode, but I'll give memtest a whirl anyway. Hopefully is it is dodgy RAM it will be easy enough to replace, I've got loads of SD-RAM.

It was the ram in the end, I took out all the RAM and swapped it around, and I set it tp pc133 speed int the BIOS as it was running at pc100 before. It now seems stable (touch wood)... I'm gonna give it an extended memtest session once I get the time...

Hope it goes well for you!
