CPU not getting power...?

[Kiwi2703]

Hi there 🙂 Let me be brief:
- I changed my PC case and CPU cooler.
- Couldnt boot it, so I swapped back the old working CPU cooler and reassembled it outside the case with just the bare minimum of things.
- It should work now, but no, it powers on, everything spins for a few seconds then it turns off. I have to cut the power or hold the power button for 10 seconds or so before each try.
- Found out that the CPU is cold to touch and not getting warmer even after 15 and more seconds of being on.
- The 24-pin and 2x4-pin connectors are reading good voltages, so the problem is somewhere between those connections and the CPU.
- This leads me to my question: What is most likely to be the faulty thing here? Motherboard, CPU or PSU? Thanks!!

To me it sounds like the board as you are getting power on and no beep codes. Having said that, make sure you have a speaker plugged in (if there isn't one on the board) to be sure there aren't any.

CPU would be far down the list, simply because a faulty CPU is so rare.

Thanks for replying. That's what I thought, too. But I need to be sure before I buy a new component.. Is there any way to test it? I have a multimeter but I don't know how to measure the motherboard directly..
Also, unfortunately I don't have a motherboard speaker...

Get a speaker. There could be a beep code telling you EXACTLY what the problem is.

There probably wouldn't be any, right? Because as far as I know, when the problem is something like this, with the CPU, it doesn't beep at all..

Depends. Dells beep 7 times to indicate a bad CPU.

What it comes down to is the fact that we will be grasping at straws by not know if there is a beep code, at if so, what it is.

Yea, you're right. Anyway, faster than getting a speaker will be to have it taken look at in some PC repair shop. I will go there tomorrow.
I just needed your opinion what you think is the most likely culprit. Thanks!
Although I still don't understand what could have happened to a perfectly fine motherboard during a careful swap between cases...

what are all your spec.sometime clear cmos do the trick

Denis, trust me, I've done everything. Battery taken out, CMOS cleared, I even flashed the BIOS with a new version... No luck.

MoBo: Asus P8Z77-M Pro
CPU: Intel Core i5 3570K
GPU: ZOTAC GTX760 OC
RAM: 4x4GB 1600MHz Corsair Blue Vengeance
PSU: Corsair TX650

HA! did you try with onboard gpu

Yes, with and without, numerous times... I've already spent around 20 hours total just figuring out what's wrong.

And how did you flash the BIOS?

Well you really did everything so far.so as ketchup mention,get the speaker for the beep codes,
