I have a problem with my computer. I try to use the internet and I cannot. I tried to check the D drive and it say's that the file is corrupted. I tried to use cmd and the screen blinks for a second and it just disappears. I cannot use the cd/dvd drive either becauses it refuses to even play songs or watch movies. I thought it could be a virus so I decided to buy an antivirus but since I cannot access the internet or run the  CD, what could be the problem wih my desktop???

download it..and run it(if u are running it in another computer click on save as and save it to ur flash drive, and once u plug in ur flash drive to another computer, make sure u copy it and paste it to ur desktop of another computer that is infected)

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.
