Having problems with your Dell Dimension E510 PC Desktop ?

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.

Answers :

Could be a monitor issue. Are you able to test the computer on another monitor or have another computer to test the monitor? If the monitor tests ok then I would check cables and make sure the cable is fully seated. Then try running windows in safemode or low res mode and see if the problem continues. To get the selection screen for these options continously press F5 as the computer startes to boot up and that will bring up the windows boot menu. If it boots up in low res mode or safe mode than it could be a video driver or hardware issue. Make sure the video settings are not out of range for the monitor. If th refresh rate(Hz) is too high that can also cause this problem.
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.
