Booted PC, loud pop, now it's dead :C

Gamer_Pollution · Apr 30, 2013

So, I had a half day today, so I came back from school and was booting up my PC, gonna do some work and stuff. But, after I pressed the power button, I heard this loud pop and it didn't boot up. I tried again, and I realized that it was dead. So, I opened up my side panel and started to investigate. I didn't see anything suspicious, nothing burnt or out of place on the motherboard, didn't smell anything either. So, since I was stumped, decided to ask the community.
Do you guys think that I the motherboard shorted, a blown capacitor or a failing PSU?

This PC is also only five months old also, so RMA shouldn't be a problem.

System:
CM HAF XM
i5 3570k 4.0 GHZ
CM Hyper 212 Evo
Asus P8Z77-V LE Plus
2 x 4GB Patriot Gamer 2 ram, 1600 MHZ
Corsair HX850
Crucial M4 128 GB
Seagate Barracuda 3 TB Hard Drive
Gigabyte Windforce 2X 670

Thank you!

If I put this in the wrong sub forum, my bad, didn't know where to post.

wow thats unfortunate. most likely the power supply. Which one where you using?

ur6beersaway · Apr 30, 2013

PSU time, hope it didn't take anything else.

Azn Cracker :

Which power supply? A Corsair HX850.

I am hoping it didn't. I'm going to try and borrow a PSU from a friend or bring it into the store I bought the components from to see if they can lend me a power supply to test everything.

Let us know how you make out.

Gamer_Pollution :

Im sure you will be fine, quality power supplies rarely take out other components when they fail

C12Friedman · Apr 30, 2013

Although that would normally be quickly associated with a PSU failure, with an HX850, I might also suspect the motherboard's VRM. Having access to a known working PSU is a big plus here for troubleshooting.

swifty_morgan · Apr 30, 2013

did you try another outlet?

Gamer_Pollution · Apr 30, 2013

swifty_morgan :

I tried another outlet, and another surge protecter, and another power cable. Still doesn't boot.

Gamer_Pollution · Apr 30, 2013

C12Friedman :

How would I check out the VRM without having access to a working PSU right now? All I got is my HX850, which looks pretty dead right now.

C12Friedman · Apr 30, 2013

You would need to remove the motherboard to look for marks on the underside of the VRM area. I might suggest using this guide http://seasonicusa.com/RMABeta/JumpStart/JS.pdf to check the PSU operation also
edit: ignore that it's from seasonic

C12Friedman :

Aight, I'll take out the motherboard from my PC as soon as I can and reply back.

Gamer_Pollution · Apr 30, 2013

C12Friedman :

Ok, I just removed the motherboard from my PC. I don't see any marks of any kind by the VRM, or on the backside where the VRM is located. Also, on my Asus motherboard, it is labeled Digi VRM, so I'm going to assume that is what you meant.

C12Friedman · Apr 30, 2013

Try the paperclip jump on the PSU (the seasonic guide), see if the PSU fan turns on at all

Gamer_Pollution · Apr 30, 2013

C12Friedman :

Nope, the PSU fan didn't turn. Nothing happened at all. Probably a died PSU.

swifty_morgan · Apr 30, 2013

check the switch on the back of the supply.

Gamer_Pollution · Apr 30, 2013

swifty_morgan :

Did, flicked that a bunch of times also.

jagui · Apr 30, 2013

If you have a multimeter check the 12V and 3.3V pins (orange and yellow cables on 20-24 motherboard pin connector) for voltages. Some PSU fans don't spin until they hit high temps. Also very important check the 5Vsb cable (purple one)

Gamer_Pollution · Apr 30, 2013

jagui :

Unfortunetly, I don't have a multimeter. Gonna see if the friendly neighbourhood Canada Computers might let me borrow one/test it for me for free.
*Edit* called them, said I have to pay for diagnosis. $50. Aw hell nah *Edit*

swifty_morgan · Apr 30, 2013

warranty....................

Gamer_Pollution · Apr 30, 2013

swifty_morgan :

I know I have a warrenty, but, I would have to pay for shipping it to Corsair, and if the motherboard ended up being the problem, I would of wasted $20+ bucks for international shipping (Canada to US) and up to 3 weeks of waiting. Then, I would have to RMA the motherboard. Better to figure out what is wrong first.

jagui · Apr 30, 2013

I forgot, in some motherboards USB ports receive power even when the computer is turned off, so you can charge a phone for example. And if you have Ethernet connected, you should see the green led lit. They receive power from the 5Vsb (standby) line. If you don't see any light on the Ethernet port or the USB ports don't receive power then the PSU is 100% dead.

C12Friedman · Apr 30, 2013

Gamer_Pollution :

With that information, you can safely pronounce the PSU dead - I'd say do the Corsair RMA

jagui :

I'll try that as soon as I get home, in about 4 hours. I'll reply back.

Booted PC, loud pop, now it's dead :C
