Our computer screen just went black. Can't get windows or anything to start on the monitor. I hear the computer buzzing but it won't do anything. I tried rebooting, tried F8, looked at all power cords etc. Nothing. Could it be a virus? Hard drive? Motherboard????

Re: Monitor 'black' with blinking power light
It helps if we know what kind of computer you have, and the model. Go to the manufacturer's support site online. (HP.com, or Dell.com, etc) and search product support for your model # and then search for blinking lights or error lights + black screen or search startup problem and see if you can find the page that explains what the light codes for your system indicate.
Your power supply may have failed. See also link to startup troubleshooting here.

Doesn't start as in nothing happens when you hit the power button? Or are you saying the Desktop is black, but it seems like windows started and went through the boot process?
If nothing happens when you hit the power button: Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.
Have you tried another monitor on the computer to see if the computer is working? When you turn the computer on, do you hear the sounds of normal startup (usually a beep from the computer, then hard drive activity with blinking lights on the front panel, and finally the Windows startup sound through your speakers)? If you do, the monitor may have internal problems, there might be a broken wire in the cable from the monitor to the computer, or a bent pin in the plug at the end of the cable. If the monitor turns out to be the problem, just replace it. It's tough to find anyone to do monitor repairs, and the low cost of LCD monitors today makes it uneconomical to repair them anyway.
But if your computer is still having problems starting up, the monitor will come on, show you that LG logo and then blank out. It's not actually turning off. This isn't happening before anything starts; it's because nothing is starting. The computer's not booting up and there's nothing for the monitor to display. If the computer still at fault, contact whoever it went to for repair. Find out what they did and let them know it's still not right.
ope this helps you straighten things out. Thanks for using Fixya!
if the screen was fryed the fuse would of blew which means there would be no lights at all.. the best thing you can do is plug your screen into another pc to see if anything happens.. if nothing happens then yeah your screen must of messed up somewhere.. but if your screen works on another computer then your graphics card config cant be right somewhere along the line
If a monitor shows a normal screen at startup but goes bad after the Windows logo disappears, your Windows video setting is probably not compatible with the monitor. You can start Windows in safe mode to select a compatible resolution for your monitor.
