So, here how it goes. From quite a time I had problem with my audio input. You need to press cable in certain angle to hear something from headphones. But, oh well, happens sometimes. But then there were bigger problems. There was random signals from bios five times, it means that there is a problem with CPU. But then, with some brilliant idea, I unplugged my speakers from output in the back and... well, it worked. Last time bios gave me a single signal that there is a problem with RAM`s refresh. So again, after pull one of the RAM and put in again... it worked. But again, there was low Vcore on my CPU (0.880, there should be like 1.2 V). So I tried to fix this in bios with option "fixed". After exit from bios... gone. No system working, all components were ok, but mobo didn`t even gave me a signal. So I needed to restart my CMOS settings with jumper. After quite some time it worked. But I have random problems like hard crash in F4, I think it`s due to low Vcore. Even now there is a problem with ethernet. It`s losing connection with cable, working in minute, disconnected, working again etc. Even know the light on my Z3 computer box there is like strange light on power switch and light indicates that HDD is working, even if it`s on 0% of use. I don`t know seriously what`s going on. It`s looking like the main problem is motherboard. So i ordered new and waiting, but I want to be sure. All components working fine, normal temperatures for CPU and GPU, HDD working I don`t know what`s the problem. The guy in some shop tell me it`s looking like a mobo problem, but I want to confirm this.

My specs:
CPU i5-4570 3.2 GHz
RAM DDR 3 4x4 GB Ballistix
HDD Seagate SATAIII
GPU Radeon RX 470 4 GB
Power: Corsair 500m (500W)

AND MY MAIN HERO: AsRock B85 Pro 4, socket: 1150, DDR3.

Sorry for my poor english, I`ve tried my best guys.

Thanks for anything that would indicates the problem.

to be honest, i think you've more or less diagnosed it yourself.

given you had to push the cable in at an angle, it's possible you've somehow damaged the mobo, maybe somehow shorted it, i can't be certain. I think getting a new mobo is the best solution, and all you can really do is see how you can on once it arrives and you fire it up.

Specially as you had so many random (but possibly linked) failures or errors on different hardware. it seems likely it's the mobo. i doubt it's your PSU, as it's a fairly good one. If that is, it's the CX 500m, you weren't very specific about the model. So i think your following the best course of action.

Give yourself the best solution :)

Yep, that`s the one :) All other components working like a charm, but mobo have problems with quite some time. Anyway, thank you for your answer, because you are like third person telling me it`s probably mobo. I will update this post to inform anybody with similar problems if changing mobo was the right idea (maybe it will help the others), but I`m 99% sure it`s the problem.

Thank you :)
