Oh dear what have I done. I had a 'working' system. I had small USB boot issues but my Rift DK2 has been playing up - not being recognised etc. fixed by removing the USB and reconnecting so I took the plunge and updated the BIOS. Others reporting booting issues improved without some of the USB issues etc.
22c as posted by gigaman won't boot Windows, page fault in non paged area, and I can't get in to the BIOS via DEL, system just locks up. Fortunately I could still get in to Q-Flash so put the latest 22g, from the Gigabyte website, into the system.
At least that boots into Windows and the BIOS but any changes I make to try and overclock the system result in a reboot and the MB reporting the settings don't work.
I'm a really amateur at this and have no idea how to go about systematically working through stuff to find the problem.
I have tried putting the F1 BIOS back in (I'm pretty sure that's the one the board had from new) but Q-Flash tells me it's too old and refuses to load it
Any help gratefully received!
