Thanks for the info Dark Mantis, I did use the @BIOS utility. I worked out the disabling of the splash screen and disabled it, rebooted and my troubles started all over again, and again to get back into Windows I had to remove the CMOS battery again and I then was able to restore to a last know good start up. It appears I cannot make any changes at all in the BIOS as whatever I try causes this problem.
I will use Qflash as you described. One question, can I re-flash to a lower revision. I went from F4 to F9 and thought this new revision might be the cause, I only need F7 to be able to install the E8400 CPU.
If you feel it would make no difference then I will stick with F9.
