use sfc/scannow. this will reset any system files you may have themed, ie .folders. wmploc , system clock etc, but should sort your problem, then re theme your pc. i believe you dont really need gamebooster. you havent filled in your system spec so i cant be sure but gamebooster is for pretty old ish machines ie vista with 1 GB of ram
SFC /SCANNOW Command - System File Checker - Windows 7 Forums
