|When I would start up my PC it was all like random colors and pixels and snow. I opened it up and it was incredibly dusty and I used a can of compressed air to get it all out. Still didn't work. I moved some things around and what seemed to work was fidgeting the video card and RAM. Computer is working fine now.|
Anyway to prevent this in the future? What was the cause? Should I get a new video card just in case?
Thanks in advance!
