Actually the you cannot do that to the CMOS chip. He probably just deleted your Boot.ini file in your Windows folder.. This guy is such a noob, he has no control whatsoever. Whoever got fucked in the A by this is retarded and you do not deserve to be on a computer.. I recomend you disable your System Restore, beacause for one, Viruses love to use that as a hiding place. I would download Avast Free Edition and run a schedual boot scan. Or go into safe mode and scan. Backup files and do a clean install if you want.
