Old monitor on new PC won't work

[Reyter]

I put together a new computer for a friend. Not my first but I am not an expert either. I made it at my place and set it up using my monitor. Everything worked as expected and there was no problem.

She took it and hooked it up to her old monitor but the monitor won't work though it works fine with her old PC.

Don't think it's an issue with the power supply as neither mine (which works fine) and hers are running the power separately from the computer and it is 750w regardless. Both mine and hers are quite old LCD monitors connected using VGA sockets.

Anyone have any idea what the problem may be?

Do you get any video at all during boot-up (POST)?

Apparently not though I wasn't there to see for myself. I am told it is just a black screen.

You or somebody should check all the connections again. One or more may have come loose during transit. This includes things like graphics cards in their slots.

Ok, I will check. I did a Google search previously and it seems this problem is quite unique. That is what it may be (something came loose during transit).

I'm really sorry and thanks to those who replied or considered the reply but couldn't figure out the problem. I went there today and it turns out she had it plugged into the wrong socket.....

All's well that ends well. :haha:
