Let's say I was not in a very good mood afterwards.
I put my DENEB into the machine and when I wanted to mount the USB backplate for the external connection accidentally dropped the little screw on the motherboard, somewhere near the mouse ports. This has happened to me before but never with an effect like this. I have cleaned motherboards in my sink and they work fine afterwards. But this, $%(@#(#@(#$@
I'm on the lookout for a replacement motherboard but they are harder to come by these days, or extremely expensive...
