Urgent computer (building) help

[Shadowknight]

My brother had a new build that wouldn't start up. Turned out the RAM was bad. Try replacing it with different sticks.

The only PSU I could try that with is my home computer's ... which is a 350W and I don't think could handle the hardware plugged into his mobo. I could do it the other way around though... Take his PSU home and plug it into my comp. That would have to wait until tomorrow though and I hate to leave a friend hanging like that.

Dead comp, half open, parts strewn across the room, boxes everywhere, 2am, etc...

So, thoughts on culprit? PSU would be the easy way out but it seems I'd rather blame a mistake on my part.

Don't plug his PSU into your comp, incase it's a murderous PSU, like with a short to mains on one of the lines.

Do you have a power cord connected to the power source?

Yes. 🙁

RAM was some nice Corsair XMS sticks... could give it a try by sticking it into my mobo I guess, but I doubt its that.

Re: Tick... yeah, but I dont know what else to do anymore. Still feels like my fault, somehow, even though a faulty PSU is outside my control. Bleh.

Just use your 350 watt in his comp. It will at least cause the fans to spin up, which will help you diagnose the problem. Or take it to a local comp. shop and let them test it.

you might get a vacation for this.

Asrock 939 is NOT a 24-pin mobo. You don't use the +4 part of the 20+4 pin connector. That is a bozo no-no. There is a separate 4-pin 12V plug for the 4-pin socket about an inch away from the main 20-pin along the top edge of the board.

Muahaha, quintuple 7900GTX 512 MB SLI, dual quadcore Opterons, eleventy billion GB of RAM, and one Super Jigga Byte of hard drive space. LCD = 89263491263 cd/m2

Boot the mobo, cpu, and one stick of RAM outside of the case (on something non-conductive of course, cardboard box or something). Make sure the main mobo power (24pin) is connected, as well as the 12V 4pin connector (though probably not necessary for this quick test, no reason not to). Lastly of course make sure the CPU fan is connected. Use a screwdriver to short the two power pins where the power button connector would go. You just need to tap it. Tap it again to shut it off.

This is bare minimal. If it doesn't start up still, use your 350 W which more than likely would power his full system, but even if not it would easily power this minimal setup just to verify what is working and what isn't. My first guess is PSU. but some mobos arrive DOA and would exhibit the same symptoms, but a quick PSU swap is easiest and first thing to try.
