Forget reformatting your PC. This is a bloody process. If I want to come out of it still breathing, I'd have to download RegRepair, a shareware that could fix my PC's errors without needing a total overhaul. Unfortunately for those whose computers are not running on Windows 95, Me, and 98, RegRepair would be impossible to use. I got another alternative though - the RAMBooster. Obviously, the name says it boosts your RAM's performance, squeezing up files so your processor can run through your system as the RAM makes more space. It's free, but don't look for a customer support service to assist you.
