|sounds like bad hardware: if it was just drivers, the graphics wouldn't be screwed up until after Windows loads, but because the image is distorted in the BIOS too, it sounds like your graphics card is toast. if the card is old, or if your power supply is cheap, it's even more likely that your card is fried.|
does your motherboard have onboard graphics? if so, plug the monitor into the motherboard to bypass the external card and see if the images are still screwed up.
and please, PLEASE, start using "the" instead of "da"
