code 32

Hi, So my PC has been randomly shutting off. I will be using it and doing any task from watching youtube to playing Warzone 2.0 and the screens will just go black and so will the rest of peripherals (mouse, keyboard, etc). The PC will sometimes boot back up normally but it will usually boot up...

I have been using my PC for like 5 years with no issue but recently, I booted up and nothing show up, can't even access the bios. I have 1 stick of 8gb ddr3 ram installed; I tried switching the slots and it booted up with no issue. I shut it down and power it back on and the same issue happen...
