Did you look in Administrative Tools Event Viewer to see if it had the error report? What you describe sounds like something I had about 6 months ago and the error report stated the PC was rebooting from a bug check and that turned out to be a bad stick of memory.
Yes ive done it and was searching on google but didnt really find anything!
The computer has rebooted from a bugcheck. The bugcheck was: 0x1000008e (0xc0000005, 0x848dc00c, 0xaa79ab4c, 0x00000000). A dump was saved in: F:\WINDOWS\Minidump\Mini042606-13.dmp.
Ive tried 2 different version of forceware i now have 84.43 and i tried 84.21
And my ram timing was set at 2 i tried lowering it at 1 but it didnt help!
I tried using one stick of 512mb at a time (even i know the min specs is 1 gig) but i came out with the same issue. I tried both stick one after the other!!!
