Key point 0 ***is of adequate power***
I tried using a 250W PSU for a P4 3.2 GHz machine with an ATI x160Pro video card - it lasted all of 20 seconds

we tried to use the dells psu which is 250w but the cable had 12 pins ports what ever they are but ours is using 10, so the only other machine we had that works was an old pb but with only 100w we took everything but ram and 1 graphic card out but still got the same beeps. i have a mate that has a spare psu but is bumming about in america for the next couple of weeks. but i think more and more that it could be the motherboard.
still will post back when i hear from either person the psu or the tester.
i do how ever have another small problem but not connected to this do you think i should start another thread in one off the other forums or just post it here.

 That was close! I am glad you did not try to force it, as others have -  . I forgot there may still be old Dell PSUs laying around - they are evil! I apologize for not warning about making sure it was ATX (today's most common standard) compliant. For awhile there, Dell used proprietary non-ATX compliant PSUs and motherboards - Dell claims to keep costs down, I think to force users to use more expensive Dell replacement parts. Sadly, connecting standard ATX PSUs into a non-standard Dell motherboard was often not pretty. 
If you mean an old Packard Bell, then that PSU might not have been ATX, but AT and would not work anyway. AT PSUs have a "cable harness" - a cluster of wires - with the main power switch at the end that connected to the front panel of the computer. AT PSUs do not provide all the necessary voltages ATX motherboards require for normal operation.

If it is a different computer, then definitely, start a new thread. If same machine and unrelated to this problem, it is better to start a new thread to avoid confusing or conflicting advice, and so future readers searching for resolutions to their problems don't get confused.

thankyou i didn't know about atx and at, you learn something new everyday and i just have. yes i tend not to force anything a lesson i learned years ago lol. i will then get onto my mate and the other guy to speed up the process off finding out if the psu is the problem
thanks again for all your help will let you know the out come soon
i thought posting in a new thread would be best i will do that as soon as i can

The ATX Form Factor Standard ensures ATX motherboards, cases, power supplies, drives, cards, etc. are compatible - mechanically (shape, size, mounting holes) and electrically (correct voltages, cable connectors, and connector wiring). This way, you are not forced to order proprietary parts (as you are with laptops) and you can buy an ATX power supply from PC P&C and install it in an ATX case from Antec, and use it supply power to ATX motherboard from Gigabye, video card from XFX, and hard drive from Western Digital, and RAM from Crucial.
