Power Problem

[Frankie]

Well to narrow it down i would suggest disconnecting everything, harddrive, dvd, cdrom, remove soundcard, and Graphics card, so all you have left is the motherboard, ram, cpu and heatsink and fan. I would then boot the computer to see if it stayed on. If it does stay on then i would shut down and add one thing at a time, like dvd ect. If however, it shuts down with only these few thing connected then it is one of these things causing the problem.

i have a new PSU ( i needed a new one anyway cos it wasnt high enough voltage)

ok so i got it today and connected evrything (as far as i know)
i disconnected everythin (inc main HDD) and tried to turn it on,
it lasted about 30sec before starting to make quiet noises then turned off.

please note, i did NOT apply thermal paste as i dont have any (is it essential?)

i am absolutley stumped and i am despairing about it.

Just a note.
i sent my computer to a repair shop.
they told me that they cudnt do it bcos they said that the heatsink had been removed with force and that he wudnt boot it up for fear of the CPU dying.

i got the computer back and he had bent the feet of the heatsink as if the "pirate" had tried to force it back into place

i took it home and bent the feet back and applied more thermal paste and put the fan in properly

and HEY PRESTO!!!!!
it lives!!!!!!!!

thanx so much for all ur help guys, its much appreciated!!!
