Crashing issue

I used the windows memory diagnostic and I ran it twice.

My PC has been up and running now for over 24 hours without dropping to the bios screen so I am pretty sure my problem is resolved (fingers crossed here).

Well, seems my PC is still restarting. Ran Memtest86 for 2 hours and a half, 4 passes 0 fails. I took out some of the extra HDDs to see if it's the PSU, and it still crashed. Now trying my RAM one DIM at a time. Weird thing I noticed is that it never rebooted on me while playing, only when idling or using normal apps.

I hope you get it sorted out soon Bombs.

It sounds like the exact same issue I was having except for the fact your rig would never crash to the bios screen while gaming.

That may have just been happenstance though.

If you have any place you can order ram that has a 15 or 30 day return policy you can always order some and then return it if it does not solve your issue.

Well, I think my problem might actually be my video card. The computer crashed using either Ram DIM alone, took out the extra HDDs and it still crashed. Updated my Bios (mine was actually pretty old), sped up my Sata drives access but still crashed. Replaced my vid card by a Nvidia 7600 GT I had lying around and it hasn't rebooted yet. I'll keep this set-up for the week-end and if it doesn't reboot, I'll look into filing an RMA for my vid card (it's only around 6 months old). If it does crash, I'm gonna try running Memtest over night to let it do 10+ runs.

I found this thread Bombs relating to ATI driver issues

ATI 5850 Win7 Driver Issues? - drivers - windows-7

There is a work around in there for the issue that does not effect performance or stability.

Worth trying out maybe

I will try it on, although the computer did the same thing last night with my other GPU. I'm still thinking it's a PSU issue, but can't really do anything about it till the start of the week, so I'll keep trying other things like an overnight Memtest86 and adjusting my idle GPU clock speeds.

Just a quick update :

I got my new PSU yesterday and the computer hasn't rebooted yet. So it looks like the problem was the PSU after all.
