Did my PSU just die?? Please help. (Video posted)

post #1 of 26
Thread Starter 
Hey guys,

Just finished loading the operating system on this new rig im building for one of my engineers. I put all the drivers on yesterday, loaded up the samsung ssd magician software, and it was working perfect. Then i went to turn it on this morning, it loaded into the os and then just shut off, and refuses to power back up. If i hit the cmos button on the back of the motherboard or unplug the psu for a minute it will try and restart but it doesn't. Please help. Thanks. Its not overclocked at all yet. No BSOD either, just shut off.

PSU: PC Power & Cooling Silencer Mk III Series 850W Modular
Motherboard: ASUS Rampage IV Gene LGA 2011 Intel X79 SATA 6Gb/s
CPU: Intel Core i7-4930K Ivy Bridge-E LGA 2011
RAM: G.SKILL Ripjaws Z Series 32GB (4 x 8GB) F3-2133C11Q-32GZL
GPU: AMD Firepro v7900
Cooler: Corsair H100i

It is your RAM you have a bad dimm... When the RAM kicks in it is shorting somewhere. Take all the sticks out and start from the left and insert ram one at a time testing in between. If it doesn't start from the get go, insert one stick into the second DIM.

Try different sticks too, it could be a specific stick. If you attempted to OC That RAM you may have fried it that way. GSKILL does not overclock we'll in my experience.

Thank you for the reply! I tried booting with just one stick, switching the sticks out, and using the left, and second to left slots with the different sticks. Same thing, no change. mad.gif

I guarantee you that it is your ram.. If you would like me to walk you through some testing I am available right now. Let me know, I'll send you my number. I had this same issue with this RAM on another machine I was building. I could help you pin point it.

One thing that people do is they also over tighten the motherboard screws that attach to he case stand offs. Somewhere you have a short.

I'd second the idea that it is a short somewhere, not necessarily the RAM, but it is possible. I'd start at a bare bones set up. unplug all the drives, take out the GPU completely, all the RAM too. Then try and boot with just the CPU/MB/H100I cooler. It should power on, without turning off. and may even beep from lack of RAM/GPU. If it doesn't power on, then it is the MB/CPU that's shorting somewhere. (also try for a few seconds with the H100i unplugged, to see if thats bringing it down)

Also, you can check the PSU on its own with the paperclip trick. http://www.overclock.net/t/96712/how-to-jump-start-a-power-supply-psu-test-a-power-supply-and-components/0_50 This will check it can run without a load.

If it does fire up, then add one component at a time, that should narrow down the guilty party. :-)

If it doesn't, then you're looking at part of the motherboard shorting on a standoff, or something has wen't wrong with the board/CPU. Then it's RMA time. frown.gif

With no beep codes, I can only presume now that a short is present, not necessarily ram. I believed at first it was ram, but now it shows upon review that something else is going on
