Alrights guys, first off I hope this is in the right spot. This site has changed quite a bit from the last time I was on it. Alright here's the issue. My gf computer just randomly shut off last night and wouldnt boot back up. So this afternoon I decided to open her up and see what was up. I was figuring the power supply was the issue, but now I am lost. To begin with, when I plug it in the wall, the PSU fan does not turn on, the green led on the back of the case is on though. As soon as I push the power button on the case, the green led shuts off. No beeps or anything.

I cleaned up everything, made sure everything was connected correctly and in the right spot. I then pulled out my multimeter and tested all the mainboard connector. They all read the right voltage when on both before and after the power button is pushed. I tested the Power_ON, green wire, reads, 4.5 when on the once the push the power button, it drops to 0 volts as it should. I did the paper clip test, when that is done the fan will turn on the PSU and it seem it runs fine. So at this point I assumed it was the power switch being faulty. So I bypassed it and jump it with a screwdriver, the cpu fan click on for about 1 second then everything goes dead again.

What could be the problem? I pray to god its no the CPU.

Thanks in advance for the help guys.

First things first what hardware is in this computer. Second try taking every component out of the machine including the RAM leaving the CPU in the board. Try turning it on then, if it turns on then install one ram module at a time then move on to other hardware like Hard drives and DVD-RW etc.

A second thing to try is unpluging the computer and removing the CMOS battery, or shorting out the CMOS jumpers. Please make sure for both of these procedures you unplug the machine or you could damage the hardware.
