You have set the resolution or refresh rate of your display adapter to a value which is too high than what is supported by your monitor.
In order to fix this, you have to do the following:
1. Reboot your computer & press F8 to boot into Safe Mode.
2. Once in Safe Mode, open Device Manager.
3. Remove the display adapter device driver form Device Manager.
4. Reboot your computer again. Windows will boot up normally & will detect the display adapter. It will prompt you for the device driver for the display adapter.
5. Use the CD that came with your display adapter to install the device driver. Once done, your problem is fixed.

Hi keepintouch0,

Make sure that the power save settings are not set in the OSD of the monitor , and if they are set to switch off after some time , then you need to change the settings as per your requirement.

Hope this helps ...:) Let me know in case you have any queries.

My answer will help Windows XP and Windows 7 users.
When the computer starts, start pressing F8 button. After several seconds you will see the following menu.
Safe Mode Safe Mode with Networking Safe Mode with Command Prompt ---------------------------- ---------------------------- ----------------------------

If you have Win XP, there will be a menu item as 'Enable VGA Mode'. In Win 7 you will see 'Enable low-resolution video (640 x 480)'
Select this option and press enter. (XP users will have to enter again).
After the computer is ready, goto display properties and save the resolution.

- In XP right-click on desktop, select 'Properties', Click the 'Settings' tab (last tab on top), and click 'OK' button.

- In Win 7, Right-click on screen and select 'Screen Resolution'. Click 'OK' button.

(Ignore any warnings)

Restart the computer.

Set the screen resolution again to a reasonable setting.

- Be careful! If you set it too high (if the monitor does not support the resolution you select), again the screen might disappear! (Sometimes this happen automatically after installing a game)

Problem is not with Dell E197FP LCD Monitor, it happens sometime and the culprit usually is an empty battery on the motherboard. The motherboard battery is used when the mains power is off. When your computer detects an empty battery, it goes into a low-power mode.
The computer will then display as message, like "Power save mode - press any key on keyboard or move mouse".
Better to replace battery:-

• open the case of your computer;
• visually scan the motherboard for a button-cell battery (it looks like a digital watch battery, but a bit larger);
• remove this motherboard battery from your computer;
• restart your computer: it should now power up normally (you may get some warning messages but ignore them);
• set the date and time of your computer using the "Date and Time" control panel;
• you can now use your computer normally, but you will lose date and time settings when you disconnect the computer power cord, since there is no motherboard battery present to store them;
• replace the battery or buy new;
• install the new battery in your computer;
• restart your computer, and set the date and time again; the settings will now be saved using motherboard battery power.

Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computer has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.

1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
   
2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
   
3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
   
4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."
   

1 some time we can get same problem in cpu fan error . look your cpu fan fitting is lose or not? and change afan to check once time. thanks (nepal)

Try going into your Start Menu then going into your control panel...then clicking on your "power options"....then switching the options to 'always on'..if this does not work..(as it seems you may not be seeing this because the monitor is in power saving mode) try fiddling with the setup option on your monitor and find a possible powersaving mode enabled function and disable it. every monitor is different so I couldn't really help you here...if this doesn't yield results try another monitor to see if it's the monitor having the problems or the computers video card...the video card could very well be the culprit...

sounds like a faulty power supply unit

I have an LG W2261V, and an old Sharp LL-T19D1-H. The PC runs both just fine, and the PSU has plenty of power. Unfortunately the LG handles power save mode very differently, where the LG would not switch on after entering this mode unless reset (unplugged, PC rebooted, etc). Extremely frustrating, as the old Sharp never had any problems exiting its own power save mode. The LG would enter this mode based on the monitor power settings (in whatever power scheme you are using) in the screensaver tab in display properties. I fixed this by selecting "Never" for "the Turn off monitor" property. I guess this is a warning to those who may wish to buy a new LG monitor, but want to use a power scheme to turn off the monitor.
