• Answer:

  Top ten Reasons you get a blank screen on your computer monitor 1. The monitor is turned OFF or the cables are disconnected. This could happen at any time during the lifecycle of the computer. Or maybe the system has gone into power conserving mode. Perform the following checks: 2. A component in the computer (such as a graphics card) may have overheated. In older computers, the fans were very powerful (remember the loud computers of yesteryears?). Now the manufacturers assume that computers sit in air-conditioned comfort all day. So they have reduced the power of these fans that are used to cool the hardware. Follow these procedures to see if that is the problem. 3. If you have just installed the computer and nothing seems to work, it could a bad monitor or a low power supply. 4. Recent Hardware Changes. Corrupt drivers for any recently installed hardware can crash the system. To get rid of the corrupted drivers, do the following: 5. Bad video/graphics card. At this point, if your computer is still under warranty, its time to call for help. If not, you can get a computer geek to come to your house (it is cheaper to take your computer to their store) or try to fix the problem yourself. 6. BIOS – the Binary Operating System may be corrupted – Use of Safe Mode to boot system. 7. BIOS – the booting software may be corrupted – Use of Recovery Console to boot system 8. Corrupted Operating System. – Try an upgrade of the current Operating System. 9. Hard Disk Crash. This is one of the major reasons for black screens.

Backups are handy in case we need to re-install or replace a hard disk. To check if it’s the hard disk, do the following: 10. Motherboard Problems.
