need help

[jhill1]

i just put together a new computer for my friend, and we just got the last part today. now after all the parts are hooked up when we turn the power on, the computer stays on for about 1-2 seconds then just shuts off for about 3 seconds, and repeats until you cut the power. i havent run into this problem before, and have no idea what to do....

okay, how much thermal paste did you put on the processor, before you put the HSF on? what is the make and model of the motherboard, and PSU?

 

[jhill1]

i put the correct amount on, the little dab in the center of the processor...

the motherboard is an ASUS P5K-VM
the psu is a HIPER 580W

okay, you made sure the 24 pin and 4 pin 12 v rail plugs are properly connected?
I see that PSU has a lot of bad reviews, did you note that when picking out a psu?

the thing is, i had the same exact problem when i used my old power supply.... i got a new one because my old one didnt have enough power. unless its a weird coincidence i doubt its the power supply

I would rule out the PSU for now.

Make sure everything is properly seated. Unplug all drives for now.

well, it's a power issue, what happened between the last time it ran fine and when this issue started (before you replaced the PSU).
