Hi,

Computer turns on but no display. This issue is commonly caused by electrical static on the motherboard. Try doing a power drain.

If this computer is a laptop:
1. Turn the computer off by pressing the power button for a bout 5seconds.
2. Take the battery out of the computer.
3. Unplugged the ac adapter.
4. Press and hold the power button for about 30 seconds. (without any power source)
5. Put the battery back in and plug the ac adapter back into the computer.
6. Turn the computer back on.

If this computer is a desktop:
1. Turn the computer off by pressing the power button for a bout 5seconds.
2. Unplug the power cable from the computer.
3. Press and hold the power button for about 30 seconds. (without any power source)
4. Plug the power cable back into the computer.
