Hey guys, just finished my first build but im having trouble getting it to work. It won't even POST, nothing at all on the screen. Here's my specs:

- Corsair 500R graphite case
- corsair CX600 psu
- ASRock extreme4 z77 board
- Vulcan DDR3 1600 mhz ram 2 x 4gb
- core i5 3570k
- WD 250gb hdd
- some ssd i found laying about
- keyboard, mouse, etc...
- new dell IPS monitor 23 inch

I first installed a corsair h100i as well for cooling, but after the system wouldnt boot i switched back to the stock intel cooler. When i switch it on, the system case fans and cpu fan spins up for half a second like its trying to start, then it suddenly dies like the cord got pulled? Then if i wait a few seconds i can hit the power button and same thing happens again... Nothing, not even a flash comes up on the screen.

So I've already tried many of the troubleshooting threads out there, and have gone through the checklist of things such as plugging in the CPU power, using standoffs (built in on my case), and I've actually already RMA'd the motherboard so this one is brand new the last one had bent pins.

Everything is new other than the CPU which was gently used in a friends build and supposedly worked well. The last mobo had bent pins could it have damaged the cpu? I don't have any other motherboards and power supplies to use to swap out things and test, otherwise i would. I might pull the psu out and use a multimeter to test that out in a bit if that could be it... I don't think these are usually DOA though?


Oh and also I have the system breadboarded right now, and I think my mobo doesnt have a case speaker built in.... i get no beeps, ram or no ram installed. Right now i have it setup out of the case, just mobo with processor and heatsink, one stick of ram (tried in all slots) and the psu. Same symptoms. Let me know if you can help!!


Thanks
Shane

You said the CPU is from a friends system that he says works fine.
Never assume that a used part works fine!
Since you already RMA'd the previous mobo, and the new one does the same I would guess that if the PSU passes it's the CPU.
Do you have anyone that can test that CPU in another mobo?

No unfortunately I don't know anyone that I can swap parts with, and I might try stopping by best buy tomorrow and getting a new psu to test on my setup and return afterwards haha. But yea thanks for responding I hope my friend didnt screw me over here! Any chance of an Intel warranty if the chip is bad?

Unfortunately the system only comes on for a split second and the dr debug doesnt even display anything in that time!

Thank you!! That sounds great! (Well not so great because the PSU is new, but I can RMA). I'll buy a new one to test it out Im just praying its not my chip!

Would the board potentially power on normally and give errors without the CPU in just to test if the PSU can power that?

Have you tried "breadboarding" your build? That would go a LONG way to figuring out which part is causing the lack of a POST since you can take it step-by-step.

Well I bought a CX600m from best buy and it turns out the psu doesnt seem to be the problem - im still getting the same strange non booting computer :(

Any other ideas before i order a new cpu? anyone have a good idea on how to test cpu or something?
