I have been having random crashes & standby issues with my setup in the last couple of weeks (specs in sig)
I have just tested the PSU with my multimeter & all power results are fine & within limits.
I ran Memtest the other day for a few hours in dos with no issues reporting RAM as being 100% ok.
It can be ok for 2-3 days then it will just freeze or go into standby, but starts up again with no probs.
Windows events reports nothing other than "power failure".
It has the latest bios version.
It's never been overclocked & I only have the 3 cores enabled (even though I can unlock the 4th core with it) I haven't played games on it for ages. mostly used for Win7 x64 apps, music, tv & internet.
I haven't reformatted yet but may do it tonight & just use laptop for now.
Any help would very much be appreciated.
EDIT : Temps are fine too.
System temp 33C
CPU Temp 31C
