Hello there. recently i just reformatted my computer because of a nasty virus. The computer ran perfectly fine before the virus but now ill be on my computer surfing the net, listening to music and it will randomly shut off. The wierd thing is if im playing World of Warcraft it will never shut down. I can even run 2 WoW accounts on my computer at once with no problems. What could be the deal that when my computer isnt working as hard it just shuts down ? my mind is boggled can anyone help?
