Solving a Computer Monitor Problem: No Power
Mar 31st 2011Richard Everettlaptop computer
Sometimes not all of your computer starts to malfunction - the keyboard may not work, or the mouse, or the speakers, all on their own accord. Among all the components that turn off for no reason whatsoever is the PC's monitor. A monitor can shut down in a snap while the PC is working, which is annoying since the monitor is where you'll see the PC's output.
What do you when a monitor doesn't turn on even if the PC seems to work? Well, the following troubleshooting practices below can be referred to in case you're having a huge problem with your monitor:
First off you should do the routine tasks of checking the wires. Why should you do so? Well, for the singular reason that almost all monitors the abruptly turned off had their power sources removed or had been plugged off from the power source. What you should do, therefore, is check the power cable, and then the VGA cables. Ensure that the monitor is plugged correctly into the power source, may it be a socket in a wall, or in your AVR or UPS. It is best to do this while the computer is off, but it has been customary to do this even if the PC is on. You should also make certain that the VGA cable are snugly plugged in.
If doing this wouldn't cut it, it is most probable that something is wrong with your monitor or your PC. The best way to check this is to use your monitor with another computer, maybe a co-worker's PC or a test computer. If it doesn't work for the first time, try replacing the monitor's cables. Connect the monitor again using the new cables. If unfortunately it won't work again, it indicates your monitor should be repaired or replaced immediately. Otherwise, if the monitor does work on another computer, using the same cables, then your video card is having an issue.
To fix problems with your video card, you must remove the video card from the PC case itself. How do you exactly do that? Well, before anything else disconnect your PC from all kinds of electric connections so that you will not be a victim of electrocution. After that remove the case, and then locate the video card. The video card is shaped like a motherboard and has its own fan. Pull it out carefully, and then check it for physical defects. If it's too dirty, dust it off, chances are this is your main problem. Test your PC again, and hopefully your monitor is good to go.
