Q:
A: It's possible that your monitor may be bad. Try your monitor on another known working computer to see what happens. The other possibility is your computer is not working correctly. Is the computer fully booting up? Have you tried a different known working monitor on this computer? Could also be a bad video card or system board if a known working monitor does the same thing. Depending on your computer brand/model, there can be some built-in diagnostics that you could run. Best of luck.
