Okay, so today, Friday, I decided to go play a computer game. After about 30 minutes in game, my entire computer froze. I couldn't move my mouse, and the game's audio was replaced by that annoying buzzing sound (related to audio) that means "you're screwed". So, I pressed the reset button on my computer. After passing the BIOS, I saw a blue screen telling me that a recent hardware change might have caused a problem. I thought "What the hell? I didn't change anything to my computer. As a matter of fact, 2 days before, I cleaned my computer in the inside" (It was full of dust) I didn't press anything, and the computer automatically restarted, but nothing was showing on the screen. I pressed the restart button again, and this time, it actually worked. I passed the BIOS screen, but, I didn't see the "Starting Windows" and the little flag. I instead saw Startup Repair, telling me that Windows failed to start and that a recent hardware or software change might have created a problem. I decided to go ahead and start Startup Repair. It launched, and then it started fixing "Disc errors" that could "take up to an hour to complete". After about ~10minutes, the repair was finished and it asked me to restart my computer. I did, and here I am. The computer is back to normal.

 

I restarted a match in the game, and after some time, the same thing happened except I didn't get a startup repair message, just a bluescreen and a restart.

 

I checked my CPU's temperatures, and it was fine. 45 degrees. I checked Defraggler's disk status thing, and it said my hard drive was perfectly fine. I also checked EVGA Precision X, and my temperatures were pretty high, around 50 degrees with the game on. Immediately after I started Precision X, my GPU's fan got really loud, so I inferred that Precision X must be on and running for your settings to be applied??? If so, I think i'll put EVGA to start with Windows and to start minimized, right?

 

Thanks for all your help.

Okay... I called EVGA and they helped me with some questions I had about Precision X and the location of my card inside my computer. I moved it, and did a fresh install of the latest Nvidia drivers, and now everything is back to normal. Just some cooling problems on my card, I suppose.
