Hi!

I have a problem with my computer.

I have a new component:
Ryzen 5 3600,
mbo Tomahawk max 450,
hyperx HX432C16FB3AK2/16 (2x 8 3200 CL16) and
gpu powercolor rx 5700rx red devil.
I bought this on July 2020.


Psu is old 6 years RM750i

Everything worked great until a week a go when computer suddenly turned off with no reason when I was playing a Warzone.

Then problem begin.

When sometimes I want turn on red light on motherboard turned on (Cpu,Gpu and Boot). I need to force turned off with power button on Psu because with power button on the case doesnt off the computer.

I took out and reconnected all the cables and took out the gpu and put it back on. sometimes it works sometimes it doesn't.

When I do that red light stay red on cpu.
I turn it off and on psu and suddenly the computer starts up. All red light are gone and worked great until the next computer startup.
and that is not the rule. sometimes everything is fine sometimes red lights are on again not necessarily everything for example just cpu.
