So im helping my friend build a new comp. We put in a 2.6 p4 and a p8p4x mobo from asus. We get everything hooked up and power it on and...nothing. So i take everything down to bare bones video card, 1 stick of ram and proc. We tested the ram so we know thats good and the video card so thats good. We start it up and once again nothing displays on screen. It doesnt even count memory or anything and there isnt any speaker beeps.

So we figure that we must have fried either the proc or mainboard but we decided to test a old 1.4ghz p4 with the same ram and vid card....same result. The only thing i can think of is that it is a defective power supply. He got the cheapest case on newegg under 400w power supplies so i dunno what do you guys think

i dont have another handy or else i would the only one i have is running this comp i tested the atx power_ok pin with my voltameter and it read 0.00 tho...so i dunno thats with the p/s on it should be around 2 i read right..
 
pull the board and psu out of the case, and do the following on a static-free counter of some sort.

install only the cpu with its heatsink and fan, and a single stick of ram. have a cd-rom drive hooked up to the power supply, but not into the board.

you can short out the pins that the power switch hooks up to using a screw driver or a paper clip or something, and turn it on that way.


do so, and see if the system powers up. you'll get no video, but you can see if it's actually a component issue this way, and then work your way up to installing all the components outside of the case. then if everything works fine, doublecheck the studs (wrong word, i know, can't think of the right one) in the case, and make sure nothing's shorting out.
