My 5 months old rig that was rock solid is giving me endless grief. It was overclocked for a while to start of with until I started getting the dreaded BSOD (it was running at 2.5 1:1 stock voltage).
I asked for help on this forum and after playing around a bit I decided to drop everything back to stock and not OC for the time being.
I installed a fresh copy of XP and left it running for over a day unattended with very little CPU activity. I came back and it had a BSOD. I rebooted and windows would not boot because of a ?missing? file (C:\WINXP\system32\config\system).
Tried repairing windows but that didn?t fix it (same error message with the missing system file), tried reinstalling it but that created an endless loop where the computer would post but not boot from the HD, restart post not boot, restart etc suspect it was a HD boot sector problem.
I ended up quick formatting and reinstalling which BSODed so I did a format (not quick format) and reinstalled windows.
Finally managed to get it going running with the bare minimum drivers (Marvel lan driver, latest karjan sound driver from DFI and latest gforce video drivers 84.21). Also installed firefox and prime 95.
Did memtest for 1 hour at 200MHZ which was fine (memtested 2 weeks ago for 10 hours after the initial BSOD at 250MHZ with no errors), ran prime 95 (first test which is mainly CPU) which stopped after 2 hours 40 mins reporting a hardware problem.
Left the machine running at stock without any CPU load and it BSOD after less than 24 hours, tried priming again and it does roughly 2 hours 40 mins on test 1 and only 40 mins on test 2, a message appears saying hardware failure rounding = 0.5 expected less than 0.4.
I just want it to run at stock everything no OC but I cant get it stable enough. I am not sure what it is, but I am convinced that there is a problem somewhere. It is looking less likely that it is a software bug and I am suspecting hardware malfunction but I am not sure what to blame. It could be anything so any advice would be great.
