My computer's not working!! power supply

[kastro33]

My computer stoped working a while ago, iv'e got a laptop now so i havent missed it much but i want to get it sorted as soon as i can cause there is a lot of stuff on the HD that i would like on my laptop.

It all started when it wouldn't turn on, i pressed the power button and it comes on for a split second, the fan lights up and rotates once or twice, all other lights come on for the same amount of time then it just cuts out.....
i went to buy another power supply thinking this was the problem. i put it in and everything was working fine for about 30-45mins then it cut out again. i tryed turning it on again and the same thing happens, it will look like its working for about 0.5 of a second then its dead.

Any help would be very much apprieciated

Welcome to the forums.
What happened before this computer stopped working?
What make and model is it?
And do you want the PC up and running again, or just the data from the HDD?

Sorry just a quick message

just want to make clear the power does come on but only for a split second, like by the time my finger is off the button the power cuts out. but the power supply must not be completely dead cause there is power there its just not staying on.
i think its the power supply cause i got a new one and it worked but after half and hour that one went too.

If they are cheapo $25.00 PSU's this could go on for weeks.
Do you know someone who has a known working one you can borrow to determine if this is the issue ? ?
