Bad SSD board usually has another symptoms but give it a shot if anything else fails.

So I ordered 2 of every board brand new and then rolled a machine next to it and swapped parts. The good machine always work with ever board. Dead machine no go. Which leads me to. Believe I have a bad power cable somewhere. All icp on the baseboard are good and no blown fuses lol. Now here's the catch it does not seem as if my switch is getting 5v so I'm thinking maybe the wiring for the switch

Just to be clear was this a new machine or one that was working and then one day dead? I would be very surprised if there was a wiring issue. But who knows with the crap K/M is putting out there!

Well it was working and was in the shop. It had a jamming ossie. I fixed the problem and asked someone to put it back together. Back panels ect after I replaced a board. When u came back to shop it was dead and they were like I'm not sure what happened. So I asked the obvious question did you unplug the machine before you put it back together. I got a laugh then of course so I'm not sure lol

I guess a wire or the CPUB. Try several time to reseat the CPUB an clean the contacts.
