Hi, all USB ports disabled for keyboards and mice. Both work in both HP diag and BIOS, but when windows starts ports don't work. F8 isn't working for safemode so I can't get to the device manager.
Any thoughts or suggestions?

Are you trying to install W7?
If so, you can only use a W7 USB installer, and you need to run this utility to put the USB 3 drivers into your W7 USB installation flash drive.

You're very welcome.
Sounds to me like it lost the USB 3 driver.
The only other suggestion I can offer would be to install the latest chipset and USB 3 drivers directly from Intel.

That's an odd one. One immediate idea is that the controller driver(s) is /are not loading, and there may be seperate issues relating to the chipset and USB controller If you have the Windows restore media, an OS repair installation might correct it,.
If that does not restore the drivers, it's possible that the USB controller has failed- but that's something I've never heard of happening.
It is very difficult to accomplish much without a keybord and mouse.
I'd thought to try and install a PCIe USB add on card with it's own on board controller that would at least give easier access to the system for troubleshooting. I've heard of these cards cards not needing drivers- just plug and play, but if drivers have to be added, It may be possible to copy the installation files drivers and *.EXE from a CD made on another system to an internal drive and then RUN from the prompt run from a recovery disk to install/initiate the USB add on card.
Have any BIOS settings been changed recently?
Those are my best wild guesses!
