How to troubleshoot your computers display issues

First go through all the usual possibilities in the display properties, check your resolution and color depth if you can log into windows normally.

The next thing you are going to want to try is last known good configuration. It does not always work but for the 1 out of every 100 it does it makes it worth trying. To get the option to do this just Tap F8 as your computer is starting.

If that does not work boot into safe mode that way you can attempt a system restore. Try restoring the computer to before any recent updates, software installations, or random problems started occurring.

Next try updating your graphics card driver on the Internet using safe mode with networking.

If your display is still not working then go back into the device manager and uninstall the graphics card driver. Reinstall the original driver that came with the device in case you are having a compatibility issue with the newest driver.

If you get nothing on your monitor screen at all so can not get into safe mode try another data cable. If the problem is still there use another monitor. If the problem is still there with the other monitor then you need to replace the graphics card. If you still see nothing then it is time for you to test other things as well such as the ram and motherboard.

If your computer beeps when you turn it on count the beeps. Then check your motherboard documentation to find out what the beep code means. These beeps usually indicate an error that can tell you which device is at fault.
