My CPU crapped out. And the wire leading to the thing that goes ‘beep’ when you turn on cpu was broken.
In trying to diagnose the CPU issue, I had to turn computer on and off a lot.
Somehow, doing that on and off repeatedly corrupted the hard drives. So raid doesn’t protect against problems like that or power spikes that fry things.
Its a little cylinder with 2 wires leading to the mobo. Not for error codes but for the ‘beep’ that happe is when you turn on computer. Is that not a thing any more?
