Ok, my friend recently bought a new custom made pc and has had problems with his new video card. After he turns on his pc and uses it for a few minutes, a lot of times less than 10 minutes, his computer restarts . The people from the store he bought the computer from say that he needs a new moniter and everything will be just fine than. So now I want to know if the moniter could really be the cause of his computer restarting.
