I had this pc built around 2 years ago and it was working fine until this summer, where it started to restart itself after about 10-20 mins of playing games (more specifically: Blacklight Retribution and Assassin's Creed 2). I thought it was caused due to overheating, and bought myself a new fan after seeing my temperatures were reaching the 70s. The fan did help get my temperatures down, but the resetting still happened. Due to some rl things I had to stop using that PC until yesterday.
I had been playing WoW a good 3-4 hours and it randomly reset while on a dungeon. I tried logging in again after it reset and the whole computer froze this time around after only 2 mins or so. Had it happen again. Today, after running some diagnostic tools the PC shut itself down and it won't start at all.
Here are my computer specs:
1024 MB ATI Radeon HD5770 PCI-E
Phenom II X4 955 4x 3.2Ghz
2x 2048MB DDR3 Dual Channel 1600MHz (PC3-12800) and a 2048MB Kingston DDR3 667MHz (PC3-10700)
1000 GB SATA, 7200rpm, 16MM
MSI 785GM-E51 Motherboard (Chipset: AMD® 785G + SB710)
Xigmatek Achilles Heatpipe
500 Watt PSU
DVD Burner
About the test I ran:
I ran Memtest86+ and it found around 3k errors on test nr. 7. Given that the CPU, L1, L2 and motherboard are also tested I proceeded to use Prime95's torture test to try and test if that got me any sort of errors. Howerver, the PC shut down while it was running and it will not turn up again.
The PC is clean (cleaned it 2 weeks ago) and I already replaced the thermal paste twice by this point, but I still keep on getting issues. Right now I'm not sure if my problems is due to overheating, fried CPU/GPU or faulty RAM. Already tried to turn the PC on with just one RAM slot (and switching it between the slots) but it still won't turn on. There's no beeping sounds either.
Help?
