My computer is booted but monitor will not turn on

What is on the monitor when you power up? Does it boot to a login screen. No screen (solid color,etc)? Does Windows boot? Need to have a bit more information.

The boot process goes through various display modes. Each time it switches, the monitor has to set itself for that mode. This causes the monitor to flicker while it's adjusting. Perfectly normal operation.

First try to do monitor self test.Disconnected the blue cable VGA or white colour connector from monitor to the computer. Turn on the monitor and check if you are able to see colours or line on the monitor.Indicating self test monitor is working fine. If you are using Video card on computer connect monitor directly to onboard video and check. Good Luck.

no signal indicates a couple things... i suspect your computer isn't even booting up. reboot the computer while tapping the F8 key.... you should see writing on the screen... boot to safe mode. after it sucessfully boots up... reboot again... should be fine.

also is that an add on video card ?

Hi,
Try to see the video card and fell if it is hot, if the fan is running when turn on. There is a part of your computer that is hot, that when reach to that temperature it trun blank or off.
Thanks

Press F8 when you boot your PC, Then boot on SAFE Mode...

Right Click on Desktop>>Properties>>>Settings>>>Advance>>>Check the Apply the New Setting without restarting.

Click Apply then OK

Rebbot the computer to a Normal Boot

Your second step in troubleshooting this problem (after you check the connections) is to plug in another monitor to your computer. If you are having the same problem it is related to your computer. If the second monitor works fine then your original monitor is probably shot.

You can email [email protected] and provide your telephone number... he will call you to assist.

First, narrow down the problem to either the monitor, or to the computer itself. Either try the monitor on a spare or friend's computer, or try a known working monitor on your computer. I'd guess your computer is where the issue is at- it isn't booting the Operating System (MS XP or whatever O/S is present on the hard disk. if the computer is the issue, try booting from the CD which came with the computer, (assuming you have that CD). Or, you could see if some computer tech savvy person has a bootable floppy diskette. Basically a "no-boot" problem, can point to a number of problems: hardware issue (bad hard drive etc.), or an operating system problem.

hi the problem isnt in the screen its in your configuration in the bios or your OS go insdie the bios menu and choose the default option and save it good luck
