So about 3 months ago I got issue of different BSODs popping out while playing high-end video games. Codes weren't helpful, as there were about 10 different types of them. I tried to resolve this in many different ways, including: - RAM check, detected no corruptions, - Hard drive check, no errors, - GPU, Motherboard, sound card and keyboard drivers update - All Windows updates - Full anti-vir scan None of these gave any results. So finally, I dismantled my PC case, and dusted off everything, all (5) case fans included. It did the job, and only BSOD case I got was after ~11h of GPU stress work. But that was in winter. As outside temperatures risen from ~0C to ~20C, it attacked me again. I am getting random BSODs about 1h into almost any game. It would be obvious overheating issue, however it gets weirder than that. It happens in: Tribes Ascend, Mass Effect 3 multiplayer, Minecraft MP, and Leauge of Legends. LoL works on DX 7.0. That is not high end game. And at the same time, it does not crash in Mass Effect 3 SP, on max settings. It only happens on multiplayer games, even if GPU stress is a factor (lowering details seems to prolong non-crash span). I could just change GPU cooling, but I am unsure is that the case here. Even if anti-overheating actions do help (open PC case), the multiplayer factor is somewhat weird, and new GPU cooling is not free. I'm adding a few recent crash dumps. My PC general specs are: - Gigabyte GA-790XT-USB3 - AMD 790X - Geforce GTX 460 Zotac AMP! edition - AMD Phenom x2 555 BE 3.2 GHz (no OC) - 4 GB DDR-3 GEIL 4096/1600 C8 Dual, Black Dragon (2x 2GB) - Chieftec CFT-650-14CS - Creative X-Fi Xtreme Gamer (sound card) - Cooler Master 1000 PC Case (making overheating problem even more wth-like) - Windows 7 Home Premium 64b Help will be appreciated. Edit: New crash type - after running Mass Effect 3 SP for approx. 3h, attempt of alt+tab caused BSOD (STOP 0x0000000A), no issues before that.
