I recently finished building my computer from the parts I received for Christmas. First day it seemed everything worked perfectly. No lag in any game and no sign of graphics problems. Now though after getting more games it seems that just about all my games are crashing.
Here are a list of the games that are crashing and how they crash.
Team Fortress 2: Randomly Exits from 20-60 minutes of play with the error hl2.exe has stopped working.
Gmod: Randomly Exits from 20-60 minutes of play with the error hl2.exe has stopped working.
CS:Source: Rarely Crashes, but it has after 2 hours before.
Arma 2 OA: Crashes Fast 3-20 minutes, ussually freezes up and my computer automatically restarts itself.
Crysis 2: Crashes Fast 5-10 minutes, Blue Screen.
Planetside 2: Only occastionally crashes after 30 minutes. Exits To Desktop.
GTA4: 30-60 minutes,Randomly Exits To Desktop
Please note that before my games ran perfectly, so I'm thinking it's not hardware.
