"No signal" on monitor when booting up computer
My brother is having problems with his computer. When he turns it on, the monitor will say "No signal". We tried hooking up a different monitor, but still had the same problem . How can we fix this?

The computer most likely is not able to produce a video output to the monitor- to test this, connect the original monitor to another computer to see if it can display video.....

You have already done the other test,-- connecting a different monitor to the suspect computer.

The video device may be an onboard chip, if it is, you might be able to install a new video card in a slot.... wouldn't get my hopes up just yet as it is often the case that the motherboard is burned out when the video will not display.

If you already have a video card in a slot, try a different video card.

If you could post the computer brand and model ID it would help a lot. Also, take a look at the motherboard area around or between the PCI slots....

Did he by any chance upgrade from integrated graphics to a video card before this problem started?
