New PC - Occasional blue screen

[mazex]

When I build a new PC I always run Memtest86 over a full night to verify that the memory and CPU works as it is supposed to do (you download the ISO and burn a CD that you boot it from):

Or you can of course use the built-in memtest in Windows 7 from the boot menu but I like the stand alone memtest better as you boot it from a CD so you don't even need to install the OS first.

After that I run Prime95 a full night to see that it's stable and not overheating under load in the OS...

Combine with Core Temp while running Prime95 to watch the temps:

After that I overclock and tinker with voltages etc...
