I haven't touched the hardware of my computer for three or four months now. Last thing I replaced was a failed/broken Corsair H60 water cooling unit with a fresh one. It's been running like a dream since then. I have been playing heaving games on three screens pushing my computer to the max many times in the last few days.

I was just playing Rust mining a node when my computer reboots itself. The screen is black and I get 5 beeps. For my processor (link below) that means a CPU error. I waited for everything to cool down and it still has the error. Is my CPU dead? Should I try to take it off and reapply thermal paste after 3-4 months? The water cooling unit still works fine.
