New PC won't POST

post #1 of 10
Thread Starter 
Hi guys, I'm currently helping a friend of mine build his PC (via skype since he lives 5000 miles away) and his PC refuses to POST for some reason. The fan on the CPU heatsink won't even spin up.

CPU is an i5-3570K, mobo is an Asus P8Z77-V Pro, GPU is an MSI GTX570, and RAM is 8GB of Corsair Vengeance. We tried booting without the GPU and using the internal instead, which didn't help, booting with only one stick of RAM didn't help either. I'm sort of at a loss here guys. The light on teh motherboard lights up green so I assume that means the mobo is okay as well, which basically leaves the CPU as the culprit. Note that we are tre trying to get it to POST while outside of the case, so it can't be shorting out on the case either.
There's no bent pins in the socket as well, so I suspect it may be a faulty CPU.

Any suggestions guys?

edit: tried clearing CMOS, that didn't help either.

Is the 4 or 8 pin ATX Power connected. It supplies the CPU with power. Because both the HS/F and CPU refuse to power on, it probably isn't a faulty CPU.

yup, the 8-pin power is in.

Its the cpu
post #5 of 10
hey wc_eend (;

three logical possibilities cpu/mobo/psu
he could try disassamble the complete rig and assamble it again.. he should look for a mobo holder / cable / something conductive on the wrong place making contact to the mobo and preventing it from booting.
he should try another psu if above wont work. and if its not due the psu i guess its a dead cpu then..

his first time build? he should try to remember if he used too much force somewhere or something other screwed up :/

hope he didnt put in the cpu without taking the plastic socket protection out :/

Dissasembling/reassembling is one of the first things I recommended he did, which made no difference.
As for the shorting out, that seems unlikely as the motherboard was resting on the motherboard box, which is cardboard.
Trying another PSU is somewhat difficult since he doesn't have a spare PSU, and because the standby power light on the motherboard lights up, I'm inclined to say the PSU is fine.

As for using too much force, I told him that it should be handled genly (especially putting the CPU in the socket), and the plastic thing was out before the he closed the CPU retention bracket.

rather interestingly, despite powering the motherboard light, the PSU failed the paperclip test
