I have a HP s5-1126 PC running windows 7 64 bit with AMD dual core A$-3400 processor, 8 gigs ddr3 ram, AMD Radeon HD6410D integrated graphics. On start up I get a couldn't load catalyst error, but it starts and runs fine. At times I get a flash my screen goes blank and then I get a message that my graphics stopped and has recovered. Then it will work fine, but a blue screen of death is coming, at which point it will shut off and restart. Will installing a new driver fix this? I am leary because that can cause other problems sometimes. I run AutoCAD on this compuer, is there a chance this could be causing some compatability problem?
