Tip & How-To about Computers & Internet

What to do when the computer powers up - but the screen stays blank

Follow these methods, each one at a time, to fix your problem:

A) Unplug the power cord from the computer. Press the power button of the computer (yes, without any electricity source connected!) several times; Reconnect the cable and power-up normally.

B) Double-check to see if ALL the rear connections are firmly connected.

C) Test your monitor with a different computer, to see if it works well.
Alternately, try a different monitor with your own computer to see if the problem persists. Also, try using other VGA or DVI cable (the cable that connects the computer with the monitor).

D) Open the computer case and look for any blown capacitors (these are electrical tube-shaped component. When they're blown/damaged their top is NOT flat), especially around the CPU area. If you find any - Your motherboard's DEAD. Sorry. It needs to be replaced! If you don't find any - proceed...

E) Clean dirt and dust! Pay special attention to the CPU heatsink and it's fan.

F) Remove, clean and restore the memory (RAM) modules (a rectangle electronic circuit, containing lots of chips on it; Usually placed to the right on the CPU) and the graphic adapter (if it's an extension card). Try using different slots for the memory modules, if there are any.

G) Replace/test another power supply (looks like big metal box with lots of power cords connected to it).

H) Replace/test with other memory modules. Make sure they fit your computer configurations, in terms of speed (Mhz) and size (GB/MB).

I) Replace/test with other graphic adapter:
* Remove the graphic card and use the onborad adapter, if there's any.
* Remove the graphic card and use other one.

If none of the above worked for you - your motherboard probably faulty. In that case, you'll have to have it replaced. It can also be a problem with the CPU itself - but this is very uncommon.

GOOD LUCK!

Clarification: These tips are for when NOTHING is shown on the screen at all ("No Signal" messages considered as "nothing" in that matter)! If you do see something on your screen, the analysis and the solution might be different!
