Question Help! Facing issue with random crashes

[kido0523]

Hi,

Been having issues with my PC for quite a while. Wondering if Only the motherboard is the issue

Issue:
PC hangs and crashes (mostly wattman has been restored) when running chrome youtube and gaming.

Noticed before it hangs, CPU core spikes beyond 6ghz up to 8ghz. (did not set any OC , even tried disabling turbo boost) but still issue persists

Specs:
i5 4690k stock
Gigabyte Z97P-D3
Thermaltake 750w toughpower rgb - (Recently changed as I thought PSU was the issue ) old corsair 750w still works fine
2x 8gb Kingston hyperx 1600mhz
MSI RX 580 Gaming X 8GB
Cooler Master Vertical GPU Mount
WD 500 GB ssd
Samsung Evo 500 GB ssd
Custom Watercooled

Already tried the following but to no success:
1. Reinstall windows 10
2. Tried windows 7
3. Change GPU to my old MSI 7950 still problem exists
4. Tested RX580 on friend PC and works fine
5. Test all amd drivers from 16 to 19
6. Reset and reload bios on motherboard
7. Re-set CPU, RAM, GPU from slots

Right now only thing i haven't tested is Motherboard and RAM as don't have spares to swap

Should i just replace the motherboard?

Hoping somebody here had experienced this issue and help

Thanks in advance

What exactly does your system do when it crashes?

Is it shutting down (and staying off) or rebooting?
Are you losing all power (no lights, fans, etc), or is only the display going dark?
Are you getting a BSOD?
