Im posting this thread for my friend who thinks his psu is dead.

I just put in some new fans, redid my power wiring and IDE wiring. I tried to start the computer. I got to post and everything is working fine and the computer just shuts off by itself about 15 seconds into the post.

I unhooked the fans and optional things like fan controllers and left the essentials in. The same deal, except it got about 20 seconds into the post.

I think his psu is dead or dying, but im not sure.

thanks

Hi,

seeing as you were working inside the pc I would first reseat everthing like ide cables, ram and any cards.

Make sure the cpu can connecter is on the correct header on the motherboard and is tight, this is the most likely suspect so make sure.

Make sure the heatsink is not loose and the fan is spinning.

If nogo post back.

I am not so sure its the psu, will the computer boot into bios and idle for 15 minutes? if so report the temps and voltages from there so we can have a look.

Can't do any harm to hang another power supply off it just to check.

If you are sure the cpu fan is spinning and connected to the correct header on the mobo then it could very well be the psu and you should try another one

fixed it. sort of.

the cpu fan wasn't making good contact, as we had just put some AS5 on it. well both of the retaining clips on his factory intel cooler snapped off so we tied it down with paper clips. yeah paper clips. so now we know it wasnt the psu. He has a new cpu cooler on the way. thanks for the help.

Yep thats the problem remember back in post #2 I said about checking to make sure the HS is not loose in any way.

I didn't think it was the psu.
