I was using the computer for a short time, just reading news on the internet when it beeped three times and the monitor went blank and the mouse and keyboard also stopped working. I had to do a hard shutdown with the power button and tried to restart it. It turned on a couple of times without the monitor, keyboard, and mouse working then finally started back up. I was trying to have it run in repair mode and it did the same thing again. I again had to do a hard shutdown and attempted to restart. When it restarted again I had windows boot normally and went to run the norton virus scan (was up to date and previously run day before). It ran for about 2 minutes before the same problem with monitor, keyboard, and mouse. Again a hard shutdown and now I just get a continuous loud beep when trying to start it up-nothing from monitor, keyboard, or mouse. What happened to this computer--it is only about 2 years old and gets all the updates, etc via internet. Has always had virus protection--never had any problems before

Push the power button and wait for 10 seconds.

Go to Control Panel, (top right View Small Icons). Then look for Power Options. On this page, you'll have the option to leave the monitor on. You should also check "Advanced Power Options". Don't be afraid of the word, "Advanced." It only means "customizeable"

If your mouse isn't waking your monitor, try the keyboard's space bar. I found it works better than the mouse at waking a sleeping computer

Hello

If this is the first time to turn you on your computer check first the power supply of your computer if connected to their proper connector. Check your memory if clip properly in there memory slot. If you are using Video Card check it if it is properly connected to the connector. Then connect your VGA connector at the back of your computer when you have video card connect the VGA Cable of you monitor to the video card VGA output if does not have connect it with the onboard VGA output. Then press the power switch if the unit is still no visual in monitor try to search or hear a beeping sound in your computer by its on board buzzer. Find which beep you hear from your computer.

No Beep- No Power, Loose Card, or Short.
One Short Beep- Normal Post,, Computer is OK.
2 Short Beep- POST error, review screen for error code
Continues Beep- No power, Loose Card, or Short
Repeating Short Beep- No Power Loose Card or Short
One Long And Short Beep- Motherboard Issue
One Long and Two Short Beep- Video (mono/CGA Display Circuitry) Issue.
One long and three short beep- Video (EGA) Display Circuitry
Three Long Beep- Keyboard/ Keyboard Card Error
One Beep, Blank or Incorrect Display -Video Display Circuitry

Hope this help with your problem. Keep on touch in fixya

One beep during startup is "good", but THREE is not good.

Three beeps means a hardware fault -- probably that the video-adapter on your computer has failed.

Connect the monitor to another desktop/laptop, to confirm that it still works.

Turn the computer off, and disconnect the power-cord.
Remove all the RAM, and then re-insert just one stick.
Reconnect the power, and try to boot.
If you still get THREE beeps, turn it off.
Disconnect the power-cord, and reinsert the remaining RAM sticks.

If you still have the problem, then it's time to replace the video-card on your computer. Take the computer to a computer-store, so that they can sell you a video-card that will be compatible with your motherboard.
Hopefully, if you buy the video-card from them, they will install it for a modest fee -- ask them.

I wm having this same issue. Dis you ever get this resolved? [email protected]

3 short beeps means Base 64K RAM failure.

try to replace the RAM.

try to remove all external device connected to your computer. just leave the keyboad, mouse and monitor connected.
restart computer.
if still a blank screen
remove everything connected to your computer (mouse kyeboard and monitor) restart if nothing happens
open your computer and remove all devices (hard drive, optical drives, memory... restart,,, you should be hearing beeping sounds indicating motherboard is looking for memory. try putting back 1 memory at a time and checking all mem slot. to identify if one of the memory could be causing the blank screen. if both memory will not work try to use known good working memory. if you dont get to hear the beeping sound using a known good working memory. your memory is the problem.
give me more info

Mikolan,

That is so crazy.
You say you previously was able to see the POST screen and now you can't?
You say you switched monitors and card outputs to no avail? Is the card an ATI with an aux Molex power connector?
Is the puter actually going into standby or hibernation?
Have a boot disk? or a PE?
How about a Linux self-install distibution CD. Just kidding about that last one. Not really, you can see if the puter does respond.

Don't rule out a faulty power supply. Video card fail is usually one long, two short beeps at POST. or 8 short.

rset ur memory card thats all

The beeps are probably BIOS beep error codes. Through a series of long and short beeps the computer communicates computer problems that occur early in the startup processes. It's likely the problem isn't your monitor but something in your computer box itself. If you can tell us what the pattern is we can start diagnosing your problem. We'll also need to know the manufacturers name, the specific model computer you have and what operating system you are running.
