Hi all,

I occasionally get a 'blue screen of death' with a message about a 'Machine Check Exception' on my reasonably new rig which I built myself last Autumn (bundled parts from Overclockers UK):

PowerColor ATI Radeon X1950 Pro Extreme
AMD Athlon 64 3700+ San Diego
Asus A8N-SLi Premium nForce4 SLi (Socket 939) PCI-Express Mobo
2GB Corsair DDR XMS PC3200 Dual Channel RAM
XP Pro

I have never been present when this has happened. The other night for instance, I left it performing an AVG scan, when I returned three hours later; the BSOD with machine check exception message was there. There doesn't appear to be any pattern to this happening, only that the PC has been on for at least a couple of hours.

Last night I left the Prime95 stress test running for around 4 hours, torturing the CPU & Memory and no failures or BSOD!

I have googled the error and found a load of stuff, seems it may be a hardware fault, possibly due to overheating. What I'm unsure of is what to do to find out exactly what's going wrong. All the kit is still under warranty, so I would like to find the fault & return the part if possible.

Has anyone got any ideas?

I'm not overclocking. I did suspect when I bought it that it was sufficient for my new system, but only just. Can you recommend a PSU that will cover me? I have two ide HD's a DVD writer, a wireless card and a glow in the dark Saitek keyboard in addition to the hardware stated above.
