no monitor signal after power surge

Expand Post »
My monitor is not receiving a signal after a power surge during a thunderstorm.
Both Monitor and cpu were plugged into ups.
Have power to both monitor and cpu. Cpu has both red and green solid(not blinking) lights.
Have tried another monitor and still not getting signal.
System is a clone. Running XP

Have been advised to try switching video card with another and if that doesn't work - do the same thing with mother board and then power supply.

Is this the right way(sequence) to troubleshoot this problem ?

Re: no monitor signal after power surge

Does your monitor have Onscreen Display? If that works, I'd bet there's nothing wrong with your monitor. Your short list looks about right to me. Good luck, hope you find the problem.

Re: no monitor signal after power surge

Yes, the monitor has onscreen display. I also didn't realize that my video port was connected to the motherboard, it's not a separate card. Does this mean that the motherboard would need to be changed in order to correct the problem ?

Motherboard ,with onboard video can also have an AGP video slot to upgrade the video to something better.You can also add a PCI video card ,You could look around for a old 2meg PCI card [a bout 5 bucks ] just to troubleshoot computer.,The onboard video will need to be disabled to do either of these .

If you have onboard video ,it could be that you toasted the Board ,or just the video chip .

Re: no monitor signal after power surge

Do the fans run when you turn it on? Do you get any beeps when you turn it on? Does anything happen at all? Any other clues to what could be causing the problem?

Re: no monitor signal after power surge

What's the difference between AGP and PCI ?
How do I disable the onboard video.
I'll look for an old PCI card. Thanks

Re: no monitor signal after power surge

Yes the fans run, but there are no beeps.
Nothing else happening that I can see or hear.

Re: no monitor signal after power surge

Take your system to a repair shop to have it checked. It sounds very much like the internal components have been damaged, and you will need to have it checked to find out what needs to be replaced.

Re: no monitor signal after power surge

Just got my system back. The mother board was fried. They replaced it. Everything's working fine now. Thanks for the help.
