Why is there no longer a signal to my monitor?

By jeffrey.bradley ·
When I shut down my PC yesterday Windows XP Pro had updates that needed to be installed. After installing the 6 updates the computer shut down normally. When I went to start the computer a few hours later my monitor is saying it's not getting a signal. I tested the monitor on 2 other computers and it works just fine. I'm out of ideas as to what the problem is. It was working just fine untilthen.

If the cable is good, and connected properly,

you may want to check that the graphics card, if you have a separate one, is seated properly and not overheating.

Do you have more than one video port? Perhaps try the other one.

Do you not even see the BIOS boot screen? Likely a hardware problem of some sort then.

If you do see the BIOS boot screen, you may need to roll back the video driver (an updated driver from MS recently trashed display settings on a computer I was called to work on).

Try a couple of things...

As long as when you disconnect the cable - the screen says check cable, you know the screen is good.

As the other poster says, if you have a graphics card installed, try the onboard graphics - it that is available....

another thing to try is booting into safemode, or vga mode if available...

this will give you a chance to rollback, prove that the system is still working, kinda
