I see you tried a different monitor on the card....Did you use the original cable (however you have it connected) or did you use a completely different one? You'd be surprised the times I have ran across a supposed graphics card problem and it was either a loose or defective cable instead.
If it's VGA or DVI, unplug it all the way and then plug it back in fully. Does the issue continue?
Boot the computer into the BIOS, usually by pressing F2 or ESC as the computer is booting, and see if the issue is present there. If not, it's likely that it's only the graphics driver that has been hosed by the power surge.
thanks a lot you guys i think it may be my DVI-VGA adapter..been trying all your solutions and hope this is the only problem...I'll try an HDMI screen and if it works then I've saved my gfx card..otherwise well i hope I can find a decent gfx card 1000 USD,can anyone help me find one,otherwise please put this as solved fine thanx
