[SOLVED] My Pc will just freeze Randomly

[Fublayyyy]

My Pc freezes with a horrible buzzing sound, it usually happens when playing ARK: Survival Evolved, but I have had it happen while watching youtube, or even Microsoft Word. I have re-installed windows to see if this would help but it went back to doing it. When it freezes like this I have to hold my Pc power button until it shuts down.

Pc specs are;
i7-7700K
AMD Radeon RX 580
ASUS H11OM-A
1 x 8GB corsair
1 x 250 GB samsung SSD
1 x 1tb
will put my power supply when i find the box

Try running Windows Memory Diagnostic Tool, constant crashing could be a sign of bad memory.

I have, it says there are no problems, would it be worth taking it all apart and then rebuilding it, in case one of the wires have been loosely connected or something like that?

sounds like the PSU has failed to me. If you take the side panel off and see if you can hear if the buzzing noise is coming from the PSU
