Nearly every time I play Garry's Mod (Source engine), my computer crashes. I'm able to play for a couple hours, then my monitor displays brown bars all across the screen and my speakers rapidly plays the last sound that was experienced in game. I am unable to do anything after that, but a hard shutdown. Any idea what the problem(s) is/are?
Windows 7 x64
ATI Radeon HD 5770
AMD Athlon II x4 240 processor @2.8gHz
Had the computer built about 2 years ago along with the monitor. Video drivers updated with steams AMD updater and AMD's website. Game is updated automatically with each released update. Can't find similar posts
Unfortunately that just made me able to play a little longer...too optimistic I will clean out the case but don't know how much that will help i just cleaned it a couple weeks ago . I guess i'll hav too keep looking
