Hi everyone. I am having a major problem with my computer. I just installed a new CPU today and I powered it on. It worked perfectly. Now here's the problem. Within 25 minutes of turning the computer on, it turns into some sort of windowed white screen. I posted a pic to show you. Any ideas on whats wrong?
