Hi, so today I have turned on my PC, but the monitor did not detect it.
I have unplugged and re-plugged all the cables and it still did not work.

I have then tried a different cable and monitor to but again it did not work.

Finally I decided to unplug my graphics card and plug the monitor into the integrated graphics card but once again it did not work.

The monitor does turn on and so does the PC but the monitor does not detect it being plugged in.

Any ideas on what can be the problem? (It all worked fine yesterday)

Thanks

Try this instructions are for a laptop but will work for a Desktop too: Black Screen Issues and Troubleshooting

did you take the discrete video card out of computer when you hooked it up to the integrated video

The monitor still worked, it wasn't black screen, it just did not detect my PC as in it said No VGA or DVI signal.

I did not pull out the video card either.

Sorry for the late reply, the computer is working fine right now.

It pretty much fixed itself because after few hours I decided to turn it on again and it worked like nothing happened
