It means your system display card settings are too high for your monitor. Try to change the refresh rate of your monitor

It does indeed sound like a backlight problem. Generally speaking, the expense in finding a new backlight and having it fixed isn't worth it considering a new 19" monitor can be had for $150.

If the monitor was dropped, most likely you damaged the internal components that provide the picture, whether LCD or CRT. Try connecting it to another computer. If this doesn't work, check the monitor's display settings or operating system display settings for contrast or brightness. NEVER open up the monitor, because there is a high voltage capacitor that stores voltage even when the monitor is off and could kill you if it discharges.

SOURCE: Make sure Resolution is 1440 x 900......

did your monitor support 1440X900 resolution. if yes then go to desktop properties then change the resolution to 1440X900 then play the game.
if not support then remove the game from your pc.

The PC is sending out the resolution that is too high for the monitor to handle, you need to set the resolution of the PC to be the native resolution of the monitor and set the refesh rate to be at 60Hz.

You can change this option in Display option in control panel.In the display proreties dialog box under settings tab,click on advaced on Moniter tab.there you can find screen refresh rate option,change it to 60 Hertz.
This would solve your problem.

How do I repair my 19in LCD monitor, it receives video signal, but goes black screen?

Connect the "bad" monitor to the VGA-out port on a notebook/laptop computer, to see if it works normally when connected. If not, then the monitor is "dead".
If it works fine, check the "screen-resolution" of the computer's video-card, to see if the values exceed the capability of the monitor.

It seems from the begining you have had nothing but trouble, if under warranty return the item, because it will eventually fail, it is a matter of probability.

Blue screen with error

You'll need a system repair disk or operating system disk to fix this problem. Put the disk in the cd drive and boot from it. You want to get to a dos command prompt (black screen with white letters) so that you can type in the following command: chkdsk /r
Check Disk will run well over an hour so be patient. You will even see the percentage of completion going from high to low but that is normal. Just let it run to completion then reboot.

In windows xp you get to the command prompt by doing a repair when you see the options come up from the system disk.

In vista you get there from the recovery console and you will see the dos command box at the bottom

If Check Disk does not solve your problem you'll need to reinstall windows. You can do a repair install which will preserve your docs, music, pictures and videos. A clean install will wipe out everything.

Also System Recovery wipes out everything and sets your computer back to the state it was when you first purchased it.

My PS2 Slimline goes black or freezes or skips during gameplay.

No you prolly dont have a warranty at all. I dont on my refurbished disk. As far as the game not playing it has to do something with the Cd. Alot of times the people that sell the disk send it through a certain kind of scanner and it erases or screws up the CD somehow. U might wanna take it back and get it replaced if its not to late.

Monitor goes black suddenly

nvdia 6600 requires a minimum of 450 Watts of power to ensure that everything works properly. So if you want to continue using your nvdia card, an upgrade will be necessary.

If you want to test to see if it is the nvidia card, you need to remove the card physically from the system, then boot with the onboard video. This action will eliminate any conflicts between the two video cards. Before doing this you may need to go into device manager and make sure the onboard video card is not disabled.
