I am running windows XP and I have a virus but I don't know how to fix it. When I go to boot it it will go to the Windows XP loading screen and then the screen goes blank and it's almost like it goes into standby mode. I can't get the screen to come back on or anything without shutting it off with the power button. I have already done a system recovery and when I was all done with it it did the same exact thing. Please tell me how to fix this somebody!!!! Thanks!
