Troubleshoot Faulty Hardware


You get a blank screen when you power up your computer.

Possible Causes

You have installed a faulty PCI card or hardware. Or a hardware component has failed.


Here are a few methods to resolve the problem.

  • Check and resit the graphic card, memory and cables
  • If you have recently installed a new hardware, remove it and try to restart the computer
  • If you do not hear the usual sound that emits from the hard drive when you power up your computer, check to see if the power box is fused or damaged
  • Ensure that you have not over-taxed the power box. This happens when you have too many peripheral devices that are unable to draw sufficient power from the power box.
