Ran memtest when I first set it up, 48 hours and no errors.
Bios is at most current version.
Bios settings have been tried a few different ways, most recently is default settings, minus turning off all "wake from" settings (this made no difference), and turning off all LAN ports except 1. (I know this port works, it's the same port I used with Windows, but I also tried port 2, still didn't work).
So far no change to the bios has made a difference. If there's something specific I should check, definitely let me know.
I tried 3 different USBs. 2 different cruzer fit (32GB) and a regular cruzer (128GB). I've done manual setup and using the tool, on all 3, made no difference. I do plan to get another usb stick and try again but these are what I had on hand.
The windows install I did to test was done with the 128GB cruzer.
