I've had a history of bad luck with this computer...... so I decided to turn it into a gaming PC. I upgraded the RAM, CPU and Graphics Card. First, it was the RAM. No problems. Then, the Graphics card. Many Problems. I tried a game, got a BSOD. 0x0000007F (0x0000000D, 0x00000000 0x00000000 0x00000000) Never went away. Then, the CPU. Even more problems. LOADS of BSOD's, mainly PAGE_FAULT_IN_NON_PAGED_AREA. Any suggestions would be deeply appreciated.
BSOD's are often caused by faulty RAM. Have you performed an overnight run of Memtest86+ to test for RAM errors? Is your CPU supported by the BIOS version installed on the motherboard? What PSU do you have? A cheap PSU will cause all sorts of stability problems. When was the last time you did a fresh install of your OS?
Yes, your case should have a case fan, but it's not going to dramatically lower the CPU temp. It looks like you either didn't install the HSF correctly or didn't install fresh thermal paste when swapping the CPU. Is the fan spinning on the HSF? You will fry your CPU in no time flat at those temps.
