before all that try and run a anti virus on your computer, see if it will let you scan. if not follow dharan_kancha 's instructions.

Instead of fixing bro , i suggest you to  , format your drive and RE-INSTALL your OS through bootable CD . Though you will fix it , but still you be missing a lots of system files which are once corrupted they are like impossible to fix. You said your CD drive do not work , so you need bootable XP/VISTA/ or any os  CD.   Last edited: 13-Jul-09 11:52 PM
