I just finished building a computer with the following parts.
Q6600 Core 2 Quad 2.4 Ghz
Sapphire ATI 4830
320GB WD 7200 rpm
BFG Tech GS-550
The first problem I had was defective RAM stick so I am running it on two gigs right now. Anyway I have Windows XP home edition installed on it (fully updated) and now the computer is randomly crashing. The crash is basically the screen going blank with a solid color in the background (its the desktop background color).
I know it's not the best but, the CPU fan I am using is this. I totally forgot to get one so I just ran to Best Buy.
Attached is the CPUZ log.
The pictures below are a stress test to see how the CPU cooler was working.
