you mention power pack, is this a laptop or a PC ?
Smell the power supply (if its a pc) does it smell cooked?
Open the side of the computer case up.. you see all the circular/prism shaped metalic things all over the motherboard.. do any of them look
are there any small green/red lights on the motherboard?
have you tried a different power cable (kettles usually have the same power cable) or even the monitor cable. make sure the cable is cactus.
also, there's usually a little black switch similar to a light switch on the powersupply. if you see this, flick it and try again.
short of that mate you could be in with a stuffed PSU or mobo!
