You power up your computer and the receive a blank screen right after P.O.S.T (Power On Self Test) completes. You may also receive the following messages:
The master boot record could be corrupted. The master boot record is stored in the first sector of your hard disk. It is an important data structure that contains the code instructions to the the system on how to boot up to an operable system. In this case, when you power up your computer, the BIOS identifies the boot device and detects invalid information in the master boot record. Some viruses also like to attack this record causing the computer to malfunction during boot up. Hence, your system halts and displays a blank screen.
You can repair the MBR using Microsoft's standard utility - fixmbr or fdisk /mbr. Both methods rewrite the master boot code and leave the partition table intact.
