Hi, my mom's pc and mine were recently hit by viruses. I downloaded some patches, etc. from Microsoft. My pc is OK but my mom's now has a blue screen that says 'please check signal'. Only the screen comes on for 1 minute- can't get anything when we try to power on. :dead: Unplugged everything, replugged it, tried combinations. Just before this, the system would run a debugging program that would freeze everything up. Mom was getting the blue screen before, but she found out that switching the power surge off, then on, fixed the problem. Sorry, I'm new to this site but was hoping for some info because everyone wants to charge her $80 to $100 just to discuss the problem, not to fix it. Any advice is appreciated. Thanks.
