Okay, when I'm trying to play source there is a series of weird blocks going down about the middle of my monitor. They don't seem to mess up the gameplay, they're just really annoying and get in the way. It seems like if I have a window open, and then close it, it 'sticks' where the blocks are but otherwise closes. When I first saw this I thought 'looks like a driver/bios problem' but I re-checked 10 times over and I'm fully updated. Source works fine on my other pre-built Dell comp. The one I need it to work on is my custom one. Also, it runs advanced games like Doom 3 and Half-Life 2 perfectly so I don't think source is too much for it. Anyone have any idea what those blocks are there for? I have tried reinstalling also.
