Graphics card crashes on certain games

[ryon102]

I have a http://www.diamondmm.com/7770pe51gdd-diamond-amd-radeon-hd-video-graphics-card.html

I mostly crash on source games but when I crash, my screen freezes and the sound loops for maybe 5 seconds then the sound goes back to normal (like the game is still going). I can ctrl alt delete out of it pretty easily but it gets annoying. Has anyone else experienced this problem, is there a fix?

solution
1- run the game then press alt+tab then right click on taskbar then click on taskmanager then click on processes find the games process and then right click on itthen click set priority and click on above normal or high.and also click on set priority and uncheck a core one by one and then see if the game works fine
2-upgrade you gpu driver ,microsoft visuals , .net framework and direct x.
3=try to lower the games setting..
