Situation:
I just built my new computer and switched it on.....seems ok BUT the monitor refuses to get a signal from the tower.

It's a TFT into a Radeon 9550.
The computer doesn't beep.
The Graphics card is seated correctly.
The Cables are seated correctly.
No light comes on the keyboard (num lock)
And the PC won't restart/switch off via the buttons on the front.
I have to switch off at the power supply.

Any ideas guys???
