I have a home built system which consists of an i7 system, gigabyte extreme mobo and 6gb 1333 ram.
I had been running an 8800gtx until it died on me, so i decided to go for an ati 5770 HD instead.
I have got rid of all the Nvidia software properly using a driver sweeper software from techgeeks website.
I use my pc for college work, web design and the such.
In the past few days I can't run my games, even a simple game clocks up 100% cpu usage and as soon as I double click the icon it goes as though it going to run and then drops back to the desktop. the game is still running, but i can't play it and cpu is 100%
if i play ut3 it goes through the opening sequence without me being able to see it and then crashes and again cpu is 100%.
