Booting problem......again and again.

Hello,
Hi,this is what happened.Actually, i happened to start my computer after 2 months break(computer was totally covered as it was only 4 months old...hehehehe);since then my computer started to boot repeatedly before proper startup;so i tried to boot up in safe mode using F8. However I got a blue screen with an error message that said:

"A PROBLEM HAS BEEN DETECTED AND WINDOWS HAS BEEN SUT DOWN TO PREVENT DAMAGE TO YOUR COMPUTER.

IF THIS IS THE FIRST TIME YOU'VE SEEN THIS ERROR SCREEN RESTART YOUR
COMPUTER. IF THIS SCREEN APPEARS AGAIN FOLLOW THESE STEPS:

CHECK FOR VIRUSES ON YOUR COMPUTER. REMOVE ANY NEWLY INSTALLED HARD DRIVES OR HARD DRIVE CONTROLLERS. CHECK YOUR HARD DRIVE TO MAKES SURE IT IS PROPERLY CONFIGURED AND TERMINATED. RUN CHKDISK /F TO CHECK FOR HARDDRIVE CORRUPTION, AND THEN RESTART YOUR COMPUTER.

TECHNICAL INFORMATION:

***STOP: 0x0000007B (0xF7B6D528, 0xC0000034, 0x00000000, 0X00000000) "

Every attempt to boot up in safe mode brought me to this screen.
What should i do? I use windows 7 os. Plz help me out.

Thanking you'll,
