Not sure if motherboard is dead

[SkizzyA]

First let me put up my Pc specs
-Cpu Amd x4 860k quad core 3.7ghz
-Gpu gtx 1050Ti
- Motherboard FM2A58M-VG3+
-Psu 500w EVGA
- Ram 1 pair of 8gb


Yesterday i was using my pc as normal watching a youtube video, when all of a sudden my screen completely froze not in the normal sort of way in which you might suspect it is loading something slowly, it literally froze.

So i decided to switch it off by holding the power button and since then this would occur, i switch on my pc and my monitor will display "Monitor going to sleep"

I have done all these steps to resolve this

- Switched of pc by holding power button 30s taking out all plugs from sockets and walls then restart 5mins later
-Use a different monitor, same problem occurs
-Swapped hdmi cables
-Used dvi and vga cables
-Removed graphics card downgraded to an older one(Gt 730)
-Did a cmos reset by taking out battery for 5mins and putting back in
-Take out ram, start without ram, move ram to second slot and back to normal slot
-Also for some odd reason my pc doesnt shutdown by simply pressing the button it needs to be held for 3seconds for a complete shutdown

So far this is all i have done the, pc always turns on normally with my Gpu fan and cpu fan running at normal speed, lights on etc

But for some odd reason it seems it's not really on or starting up or stuck in some odd mode, or if it's actually my motherboard that's dead.

Thanks for taking the time to read this!

Are you 100% sure that's its not a faulty cpu or even my psu
i forgot to mention before this occured ever since i got my new gpu i would on random occasions, which rarely happened
when gaming my screen would stop moving, freeze and make a horrible buzzing noise through my speakers, which i always fixed by restarting.

Otherwise if it's actually my mobo and not cpu and psu i'll take your advice and get a completely new one
