Re: Graphics problem
So when the computer goes into the state of Nothing, do the screens come back on? How long have you had the card? Is it still under warranty? Can you return it? If you can return the card, great, try to get a replacement and see if that resolves the issue, if that doesn't resolve the issue, try the motherboard next.
To gmcrepair's point, it doesn't sound like a virus but it's very possible that it is. You can always run some system scans just to make sure. Get the latest free version of Comodo Internet Security and MalwareBytes and run those. See what comes up. If nothing, try the above steps.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
