Today I decided to clean my computer. I mean physically clean, not by deleting files and such. I took the panels off and removed the fans and went through it all with a cloth and lightly went over the dustiest parts with the vacuum cleaner. I finally get it looking schmico. I put everything where it was and plug it back in. Now it's quieter, and 2 USB ports that weren't working yesterday, nor for about a month come back to life. Also, since my computer had a power surge, it hadn't liked USB ports during BIOS. Now it runs USB without a problem. Summary - Cleaning your computer makes it work alot better.
