worst developer ever
I ram memtest on mine for 4 hours last night and all is well.....
I woke at 3 and it was still going so I killed it then figuring that was plenty....
Seems enough. If it didn't show errors then, the chance is low that
it might have shown errors later on.
So your Ram is out of the question.
Hmmm....A bad CPU...Never had one and have no clue about symptoms....
Symptoms?
BSODs, unexpected reboots, no correct boots.
But as I said, its not really likely to be the source of your issue.
