Here's my situation:
A few months back my power supply, RAM, and CMOS battery needed to be replaced, so I did.
I reinstalled windows and formatted my computer. Everything was fine. Then a couple weeks later, I started getting the blue screen of death. I downloaded a program called, blue screen view, to help me figure out what causes the crashes. My antivirus was a major contributor, so I reinstalled it. Same problems still. I had Avast/Malwarebytes so I bought Bitdefender instead. Everything again worked for about a week, now having the same issues.
What could it be? Cpu? Mobo? Hard drive? Video card? A driver? All these parts are pretty new. Here are my specs:
1.5 TB Western digital 64 cache
AMD Phenom 2 X4 965 processor
Asus AM3 mobo
NVIDIA GeForce GTS 250
