For a long time now my PC has been suffering from a graphical problem which recently has begun happening more frequently. Normally I can fix this issue temporarily by tabbing out to desktop then reentering the application but this only works for about 10 minutes, and then I get more graphical glitches. Eventually my PC will crash after about 3 hours or perhaps even earlier.
I have attached a screenshot of counterstrike source to give you an example of my issue

I also get graphical glitches in FSX and to a lesser extent WoW.
I have updated my graphical drivers to the latest version.
It is also worth adding sometimes, but rarely, my PC crashes when browsing the net, when I scroll down a webpage using the mousescroll, perhaps once a week this happens.
