hello i recently built a new pc and used a Connect3d Radeon X600 PRO as the graphics card. i have installed the latest drivers for this graphic cards but still have problems. these problems are that the graphics card will sometime switch the screen on and then of, the system will hand justa after booting up but will be fine after a couple of mins. when using say google news and i scroll down the page it takes ages to scroll down and does it like in 'slow motion' what could be the problem, i am running windows xp professional
