Question PC crashing/rebooting suddenly, what's wrong?

I've just started having issues with my PC where it randomly crashes and reboots every now and then.

The first few times it did it the screen froze and went black then restarted and now it also lags my game to about 10 fps for about 5-10 seconds then freezes with buzzing audio, then takes me to a very low res windows blue error screen saying something like "your pc ran into a problem and needs to restart".

Apart from the crashing and rebooting, performance is fine.

I've checked all the cables and RAM and nothing has come loose.

Should I swap out my PSU as I heard they can cause these sorts of problems?
Thanks
