RE: The ground wire connection to the P24 ground did it

Welcome... and same to you!

Your BIOS instability does not surprise me. I noticed something similar on stability when I went to the fully-linear supply from the Pico-PSU-based linear-hybrid one... I could run a step or two lower in voltage.

Also on the grounding, when I was tracing out the USB power connection last night, I noticed that the ground pin on the USB cable side of the Molex plug had pulled out (I HATE those connectors... I bet there's a good sonic upgrade available in replacing them!) and was not making contact. I pushed it back in and made sure my wire dressing and component placement (especially HDD) was right... and when I re-booted the system, the sonic 'robustness' through the lower midrange & sense of dynamics & 'bounciness' that had been missing for a couple of weeks and that I assumed was due to Alan Maher CBT's & AC filter chokes breaking in came back. They were (and still are) breaking in... but it was not just that.

I definitely need to setup better ground routing on my 'dirty' connections... I did it very haphazardly back then.

Very glad that the grounding fixed your USB mouse issue.

Later!
