[Fung]

When I press the power button, my computer display light lits up and nothing appears on the screen. Even the bios set up doesnot appear when I press the function key. Please help.

Can you test the monitor separately?
Or plug in a separate 2nd monitor?

Hardware troubleshooting through process of elimination.
Unplug the video cable from the monitor and power it on. It should show "No signal detected" or something similar. This is basically the built in test on the monitor, if you see the a message the monitor is probably fine.

LAPTOP
Unplug the power and remove the battery and hold the power button down for about 10 seconds. Plug the battery and power back in and test.

DESKTOP
Unplug the power and hold the power button for 10 seconds and plug back in and test

If you still get nothing let us know if this is a laptop or desktop to troubleshoot further.

If just a light flashes then it may mean that this is a Motherboard issue.
Do you get any Beep code with this problem?
What is the make and model of your system?
These things would help us better understand this problem.
