Problem with my build, help appreciated!!!

Hey all, thanks in advance for the great community opinions that yall give

I'm in dire need of some advice/help at the moment.

My friends computer (that I am trying to fix), is an older sckt 775 system just ran into problems today. After turning it on one day it just wouldn't turn on, or died after boot (during windows load) and then turned off. As my friend persisted in pressing, jamming, and holding the power switch on his case it eventually stopped going as far as the previous attempt (in terms of how far along the comp had turned on) and stopped turning on at all, which is what is going on now.

Now initially I had thought the switch on the case had become loose, however I tried jump starting the comp by shorting the power switch pins on the board but its not turning on. The green LED on the mobo is ON, which means the powersupply is connected and working but after that, nothing. No fans start spinning, nothing.

Any ideas what could be wrong? Since the light is on, on the mobo, that should mean the board and ps are working right? What else could it possibly be?

Any ideas, please,
thanks in advance!!!

Power supply might just be dead, but be sure to check connections with things like video cards.

I was working on a friend's newly-built PC, and sometimes it would turn on and sometimes it wouldn't. And when it did I didn't get a signal on the monitor. I put in a new PSU and sure enough it worked just fine. I'm thinking it's more a matter of the PSU being dead, but since it would sometimes power up with the old one and yet not give a video signal, it could have had something to do with how that was hooked up.

But most likely its a dead PSU.

My light was on after my PSU failed as it is most of the time I've seen failed PSU's. Usually the -5 volt rail is the culprit, and everything else is fine but you need all of the rails to pass the check to turn on.

Some shop will test it for your for free or a small fee. Everything else is fine.

Try without the video card.
Try with ine stick of ram.
Reset cmos when you change something.

Does it have onboard video at all?
What video card do you have?
Can you try a different video card?

my case may be a little screwed up, i accidentally cut the power switch cable and i had to rewire it, however for each attempt i tried using a screwdriver and tapping it on the power pins to get it to start but nothing. is that the correct way to do it?

well theres 4 sticks, shouldnt the computer at least start even without ram though?

perhaps my power switch is broken...

how do you turn on a comp without using its case front panel connectors?
perhaps i am missing something

thanks guys, would be appreciated

no beeps and i have the motherboard manual. nothing but the freaky green light :\ if the mobo is dead though why is there still that light? to restart cmos all i have to do is remove the battery and put it back in right?

btw i've gotten lazy setting up the entire system so the entire time i've been testing this all i have is the power cord plugged into the psu and pressing the power button. it should still turn on if it was working right? (i would see the fans spinning)

also, this motherboard has a 24pin power connector however when i opened it up the power supply only had a 20pin and 4 pins were unused. theres also the 2x2 power that goes left of the cpu socket and this other "auxilary" have i been plugging it in correctly?

now this is interesting i noticed... with my old power suppy, when i turn it on nothing happens, then i turn off the switch on the back and the cpu fan slightly spins for a split second and the an led fan lights up for a second.

however with my new psu, it does nothing. any thoughts?

Hey Roadrunner i just wanted to thank you for assisting me throughout these past few days. I ended up replacing the mobo and cpu with new ones, and the machine is working now. however i have an extra psu now and its currently connected with the new one.

i wanted to know, the culprit on my old setup was the motherboard dying, did my old psu cause that? or did the mobo die itself? i am asking this because i wanted to know if it was safe using my old psu in another computer, or possibly to resell.

Hope some of you guys might know this one,
thanks in advance.

ummh nope, nothing leaky or buldging. how could i tell? it still works though lol tried doing the green pin black pin test on it, and it spins.

ended up getting a p5n-d, similiar board to my intel just this one supports dual core and dual ram, so more upgrades to come!!!
