Start the computer.
After the ios info page/motherboard page is gone, start to press F8 a few times.
If you still get to the point that you see the Windows Logo loading screen, then press reset and try again.
If you have done it correctly, you will get to the Windows boot page.
Select Safe Mode and start Windows
Go to the video properties page by right clicking anywhere on the screen and adjust the video mode to 640x480 (or as low as it will go)
Restart the computer and see if that solves the problem.

If not, then do the same procedure, but go into system properties and unistall the video card.
Restart again, and install the drivers if needed.

Hope it helps.=)

When i plug up the L1975NW lcd monitor what should show up ?

"no input" means that there is no signal from computer or the monitor cable is unplugged. When you first turn on monitor it usually does a self test and then looks for signal. Not connected to PC will give a no signal. If it is connected but PC is off (not unplugged) then it should go into standby as you vid card will be sending a standby signal to any monitor connected. Sometimes the Plug and Play monitors need to register before it will recognize a standby signal from PC, so plug it up and boot up PC. Then shutdown normally, your monitor should go into standby when the PC shuts down.

When i turn it on it says no signal? Does this

The no signal can either be "no signal" or a signal that is out of range. Check first by connecting the monitor to a known good video output (ie another computer). If that works, then the problem is with the source and not the monitor. Sometimes the source computer has its resolution set too high and the monitor will not be able to process that resolution. The no signal message will occur then as well.

Signal outof range

  • Make sure the pins on the video cable are not bent or damaged.
  • Make sure there are no extension cables or switch boxes attached to the monitor.
  • Verify that you have the proper drivers installed for the video card.
  • Verify the problem at all possible resolutions and refresh rates.
  • Make sure the refresh rate does not exceed maximum value for any resolution.
  • Test the monitor on a different computer.
  • Contrast is recommended to be set at a higher range while the brightness should be set at middle range. This helps to increase the text clarity while reducing the bright background.
  • If your monitor is equipped with moire control, adjusting this may improve the clarity of the text. Moire is a wavy distortion pattern caused by interference between the dot pitch of the CRT and the picture signal. The pattern may vary depending on the screen amplitude, contrast, brightness, and other characteristics of the input signal.
  • Monitor's performance may be affected by the Earth's magnetic field. Try rotating the monitor to different directions to improve misconvergence.
  • Most video cards offer a software utility that changes the frequencies and sync polarities for all resolutions. If the setup does not match with the monitor's characteristics, an incorrect signal may be displayed on the screen. Sometimes, the image may also appear blurry.

    What does F1 indicate? My oven seems stuck on Broiler and a signal keeps flashing F1 with beeping signal. What could be wrong?

    F1 is a common failure on a lot of ge oven controllers. Although sometimes it is caused by a keypad failure. The test is to disconnect the keypad, power up the oven with the keypad unplugged ... see if you get an F1 ... may take a while ... 30 minutes or so. If you still get an F1 then the problem is with the oven control board. If so, we can repair the board for you.
