Hi there
Check the leads from the PC to the monitor, if they seated well try to boot up into safe mode by pressing F8 on start-up, if you can get into safe mode and see the monitor uninstall the graphics drivers and restart the pc, hopefully the machine will boot properly and reinstall the drivers for you.

Kind regards and post back if any more problems

You have the power cord plugged in, but you don't have the monitor connected to the computer.

Monitor is switching off immediately after system is switched on. Again when monitor is switched on, images appear for about 3 seconds and again monitor switches off.pl give the solution.


You need to determine if you is turning off or going into standby mode. When your monitor shuts off, the power light will turn orange if it is in standby or the light will turn completely off if the monitor turns off. If your monitor goes to standby, that means that your monitor is losing signal which indicates a problem with your PC. #1 Make sure cable is firmly secured and both screws are tight #2 Check your video card make sure that it is firmly in its slot. Take it out and put it back in. *as long as your computer is open give it a good cleaning with compressed air* If those things check out it is possible that your video card has failed and needs to be replaced.
If your monitor is powering off #1Check plugins- try something else (i.e. lamp) in the outlet #2 Try your PC's power cord in your monitor

Try start up in Safe Mode press F8. Choose Safe Mode, when at the choice window, to select either Safe Mode Desktop, OR System Restore, chooses system restore and choose a time before you had the "Problem" and follow instructions. This should get you back.

Black screen with AGP video card update


you really didn't need a new psu for that videocard, but it can either be a burned videocard or the monitor can't support the refresh rate the videocard is outputting.  although, the card really should default to its lowest setting upon installing in a new system, try connecting another monitor.  if you get a screen, thats good, if not, try booting into safe mode holding f8 right before the windows loading screen appears.

Monitor not supported


Well the monitor not being support is not the issue. the issue is the video card cannot produce a signal that is supported for the monitor. Its doing this to let you know also to lower your resolution because the monitor will pop if the resolutions is to high. the monitor itself does not matter if you had Vista as lond as the monitor agree with the signal your cool if it don't it will do this. Try lowing the res using another monitor then put the orginal back on and you should be good.

Thanks

On my 997sd lcd the screen after about a second goes blk but the power light stays on also stays on on the power cord when unplug and plug back in again stays on for a second then goes blk


It may be going into power save mode or its not getting a signal from your comp.

Check this by using the monitor control menu on the monitor.

Does it give you a message at all?

Also, if you have a VGA video card and its a DVI monitor and you have a converter, you may need to switch it from DIGITAL signal to ANOLOGUE or vise versa depending on your setup.

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.
