I have a Dell Dimension E510, with an ATI Radeon graphics card. Well a few weeks ago I came across the "Infinite Loop" problem, and Dell sent me a new video card. Now whenever I try to go on my computer there's lines and crap all over my screen. I've wiped out the hard drive twice and I'm very annoyed! What do I do? I tried installing the latest drivers but it didn't seem to work. I'm in safe mode right now, any tips?
