I didn't get my CPU checked, I thought if it worked it was OK!?
I'll try a different socket when I get home as I'm at work now. I wasn't aware that the CPU could seem OK for a while then cause problems, I hadn't really been pushing it much and the cooling I have is pretty good.
I used artic silver 5, and I did clean the old thermal paste off using iso-propanol. My CPU fan is a
thermaltake big typhoon, and the temperatures I have seen in the recent past have been pretty cool, around 45°C if I remember rightly, the HD however were ~5-8°C higher.
I didn't notice any other power surge, I suppose its got to be the CPU, graphics card or the HDs as they are the only thing that remain from my last problems.
Can I rule out problems with the HDs as I cant even get to the BIOS?
So can a CPU be partially faulty? Its still strange as to why its just stopped working when all seemed well. Where do you think I should go from here and are any components safe to re-use if I were to build another PC, just would like to keep cost to a minimum.
