No video signal or USB -- not power, monitor, cables, ram, cmos reset, or MOB (Pegatron Pittsburg)

[DYOUNGDFY]

Hello, running out of ideas!  Envy Phoenix 810 running Win 10 (64).  Following regular Win 10 maintenance update, system suddenly started running fan at ultra high speed and lost video.  Geeks said replace M/B.  Swapped in new Pegatron Pittsburgh board - exact match with original build. Now fan runs at normal speed BUT no video or USBs. Did the usual: checked monitors, cables, power supply,  graphics card, popped battery to clear CMOS, reset jumpers for bios and password, swapped ram, disconnected HDDs to try boot, same issues.  So my sense is the BIOS is corrupted, but with no video or active USB slots, no way to see or do anything (MOB has no onboard video, obviously USB & wireless keyboards wont work) -- WHat can I do??  

Thanks
