I cleaned my computer because my cpu was overheating. I took everything out of the motherboard. When I put the video card back in once, my computer automatically found drivers and once I manually found the driver with the same result. The video card worked, until I put the drivers in and then the computer would have to restart. Well after I restarted the computer and it went past the windows, the screen would go black and white, squares and lines and it would load again with just different patterns. It repeated this process until it restarted and did it all over again. Only solution I came up with was to shut down the computer.
