What "main cable" on the motherboard are you referring to?
The VGA (video) cable or something else?

Not only "what main cable?" but what monitor and what motherboard?

Please provide makes and models when discussing hardware problems.

I'm assuming that the whole system is failing to start, in which case it has nothing at all to do with the monitor. If the rest of the system is dead then the monitor itself can't possibly show you anything.

There are two possibilities:
1) the PSU is faulty, and is not resetting after shut down. If the fans etc do not power up then this is almost certainly the case, but could still be the problem even if they do.
2) the motherboard is not resetting after shut down.

Even when the system is shut down there is still a standby voltage sent to the motherboard. When you remove the power lead even this voltage goes away, which forces both the PSU and the motherboard to reset.

If you have a spare PSU that's the easiest thing to test first.

My money is on the motherboard though.

Maybe that's the problem.
Loose change on a printed circuit board could cause a variety of shorts.

BTW you'll get the computer to start right back up if you unplug the power supply from power or turn it off from the switch at the back.
Just so you know, so you're not risking breaking something by unplugging wires inside your computer.

I'm pretty sure that's what he meant he has been doing, but maybe he'll come back and clarify.

If I'm wrong, then the chance that the problem is in the PSU are almost negligible.

And if he doesn't respond soon we can assume he's already broken something. :O
