Your backlight might be dead. Try using a flashlight to see if you can see a screen
when it turns black. If you can, its a backlight problem. What model of screen do you have?

When i turn on it goes start to pc entering power saving mode


Are you sure it isn't the monitor entering powersave mode?
An unhooked monitor (especially flatscreen DELLs ) will go into powersave mode if it isn't getting a signal but is getting power.

First unplug and then replug your monitor. Both ends of the cord, the end in the back of the monitor (if it comes out at all) and the end that plugs into the computer.(unplug it from the wall first)

Reboot computer.

If that fails...(and you do have a video card)

Unplug everything from the computer, open the box, ground yourself by touching the metal frame of the computer case and reseat your video card....you may have to undo one screw to get it out.
DON'T drop the screw into the case!

Put it all back together and try again.

If that all fails Boot Windows (windows right?) into safe mode and change the power settings for the monitor...perhaps something got changed or broken by an update.

If that fails....

Get Linux.

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.

Screen goes black. the power light is on, but the picture goes out. if i turn the power off, then on again it comes back for about 5 seconds, then goes black again.


Check to see if this problem follows in safe mode. Reboot and when the Dell splash screen comes up tap F8 until you see the multiboot options. Scroll to "safe Mode with Networking" let the machine boot up and see if you have a screen. If you do, right click on the desktop and set the resolution to 800 X600 and reboot normally. Usually when a screen goes blank in normal mode but shows up in safe mode means you have an incompatible resolution for the monitor or graphics adapter. This may be a driver issue or hardware. If the screen boots up in normal mode at the lower resolution, then try and go to properties again and bump the resolution up a bit, if it blanks again, try to go online and update the driver for the graphics chip.

Monitor turned black when i change the resolution to 32bit


press f8 when the computer starts up before windows boots and select start in vga mode or low resolution mode. after you get into windows change the video settings again but if the screen goes black, dont touch anything...it will revert back to what it was before. most likely, the resolution you picked isnt supported by the monitor. you also want to make sure that oyu have the video drivers installed properly aswell.

Randomly lost display on my pc.. and its not a faulty card.


Try to set your PCI-E card as a first one in BIOS. There also should be an option to turn off onboard video.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

Monitor won't stay on. Error message comes up that says "no input signal", then monitor goes out.


Problem with the monitor, monitor cable, or video output. For monitor, if you have more than one input, make sure it's set to the correct one. Try a different cable. Try a different monitor. Check your video card settings--if you see the BIOS bootup screen while it's coming up then the Windows splash screen, then monitor blanks out, it's a Windows display setting. Boot into safe mode, then change settings--
  • Turn the computer on or Restart the computer
  • Start tapping the F8 key. The Windows Advanced Boot Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
  • Ensure that the Safe mode option is selected (the top option)
  • Press Enter. The computer then begins to start in Safe mode.
  • When you are finished with troubleshooting, close all programs and restart the computer as you normally would.
