Screen went black. when restarting the computer screen shows desktop for one second and goes black again

Does your monitor go black because it went to sleep, does it turn off? Do you have any lights on the monitor to indicate what it is doing?

Also I would boot into safe made by rebooting the computer & tapping F8 when the bios appears. You should be prompted with several options, one of which is "Safe Mode". Choose this & report how the monitor behaves.

try to boot in safe mode.To do that.
restart your computer continues press F8 key it will show the option select safe mode
and you can work with that and change the reasoluition and restart the computer work with normal mode..

Ok try this, at boot up press F8, when the Menu comes up, choose Safe Mode, but this time instead of going to the desktop, choose System Restore, follow instructions, and when the Calender type window comes up, simply choose a time BEFORE, the time it went faulty. This should completely restore you to working again. As long as there are NO other problems.

Unplugg any external device and restart the computer. If still not, Click on F2 as soon as the computer restarts.. It will open BIOS, press F9 & then F10. Restart the computer.

Right click on your desktop go down list to properties and left click under the screensaver tab click the power tab and turn off the power saver in other words change settings to always on and no hibernation

Press F8 continuously while starting the computer. When black screen appears eventually (right before Windows loads), choose Last Known Good Configuration.

Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.

reinstall windows ur screen resolution is not accepted by monitor

oboy, One thing to try is the flashlight test. and get backto me with your findings. Tell me, does this lcd show a nice display only for 1-2 seconds and then a black screen when connected to a fully booted PC with Windows desktop displayed? Shine a bright flashlight 1-2 inches from panel and tell me if you see the WINDOWS START Button at lower left of screen even though screen is black! Get back to me if you can. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.

the resolution set by default when you load your graphics driver is outside the range of your monitors capability.

try starting in safe mode then adjust your resolution to 640 by 480 then restart.
if this works, adjust upwards to 1024 by 768
then up again till the screen blanks.
when it does, dont panic, wait 20 seconds and the settings will restore - you then have the optimum settings for your monitor.

good luck
