motherboard noise, won't turn on

[wabbitinspace]

Hey all, thanks for taking the time to look.

I was trying to overclock my cpu 8350 with hyper evo 212 following a guide using only multiplier since I've been told it's bottleneking my 295x gpu . I have a msi 970 gaming motherboard, 16gb of ram patriot viper 3, raidmax rx-1000ae 80plus gold.

I got to 4.6 with 1.580v, cpu/nb 1.24v. Was running prime95 for stability small FFT. On test two motherboard shuts off and makes a weird hum. Cpu temps were at 56c but tmpin1 showed 90c, dont know what that means though...Turn off and let it cool for 30 minutes, when trying to turn back on, sounds as if power tries to go through it but motherboard doesn't turn on, makes that weird hum again for about 2 seconds and that's it. I pulled cmos battery will wait a but more here. I live down the street from frys electronics so I will take my psu there to check if that could be problem, but I was wondering if it could be motherboard it self? I could smell some type of burning kind of, think it came from mobo...I just bought it a few weeks back, could it have gone that quickly? :c

Just got power supply tested, everything works

Hey all never got an answer :c
something else happened here, so after a couple of days without touching the mobo, haVing everything removed. I decided to plug in mobo power and cpu power from psu, the mobo lit up, turned on, it had no cmos battery. I put in cnos battery, the ram, and hard drive, still turns on, video card gets powered. So I put in my cpu...moBo goes back to making a squeak, doesn't power on, took out cpu, it turns on...is my cpu dead or is it the Northbridge? Sos :c

Bump...?

1.580v on cpu voltage?I don't think so that is a safe voltage with hyper evo 212 air cooling.

Maximum safe voltage for FX-8350
"1.55v is officially the max, use more than that and you risk killing the chip, even if you have it @ 1.53, voltage fluctuations can take the voltage well beyond 1.55 and you will risk damaging your CPU , keep it @ 4.5 it's not worth killing your CPU over 0.1ghz. If you want to overclock more and you've got either a gigabyte or an Asrock board go into the bios and use the "disable on core per module" setting, it will disable have the cores, leaving you with a quad core, but you'll be able to overclock more & you'll have noticeable IPC improvements. "

So would this mean my cpu is dead if my motherboard doesn't power with cpu out of socket, but will power without it?

I'm not sure , maybe cpu or motherboard dead ,try to RMA that board would be the best and quick way to solve this problem I think

Okay I'll just have to try frys to see of they can test them then, just didn't want to pay that fee..Tha KS again, could use this as excuse to upgrade to 9570 and a cross hair motherboard
