I think I have problem in my graphics card,I m using Window 7 7600 x64,When I want to upgrade my graphics card drivers,setup stopped working..help me plz??

Which driver set do you use?

ATI Catalyst™ 9.10 Suite for Windows 7 (64 bit) (Released Date - 22/10/2009)

Try an older set. Its a really new driver set and may be a bit buggy or something. Try 9.7 - 9.9 and report.

I h already installed older version than 9.10, 1 more question. maine socha ki again new fresh window install kar dunga to ye problem solve ho jayegi,but jab window install ho rhi thi tabhi screen band ho gayi.... lag rha thi ki monitor ko output nhi mil rha tha.,lekin machine chal rhi thi..

OMG,Temp goes above 115C,while playing Street FIghter IV
