I have restored the BIOS to default previously (after Steve left), strange how it has all gone back to default though ?! Does default not mean the same as reset?
On board sound and graphics now disabled and drivers deleted, Nvidia drivers 327.23 now installed for 24 hours without issue - yay!
However, I foolishly enabled ultra fast boot in the BIOS and whilst I can confirm it works excellently, it unfortunately disables the USB's from working until it gets to window, thus rendering the del / F8 buttons totally useless!! The only thing I can think of is to get a PS2 connector for my usb keyboard (i have 5 keyboards here all USB!!).
This is going to be one loooooong thread, I can feel it :)
