Hi folks it's been a while so I don't know if I'm posting in the right place but I'm pulling my hair out. I recently had a problem when my screen started freezing while playing solitare now when I try to boot up I just get a black screen full of zeros. I've done a bit of googling & it's pointing to a dodgy graphics card. Is there any way to rectify this easily as I need to wait for a while before I can purchase another one. Anyone out there can help it would be very much appreciated.
