I used MSI Live BIOS.
That was a mistake! Came up with 'Verify Error', computer restarted and beep, beep!!!!!
The MSI live BIOS has been very good untill now, previously updating flawlessly from 1.8 to 1.9, 2.0.
So this time I had to send it back to my dealer for them to reprogram it to version 2.4.
Hmmm, looking at what version 2.4 fixes, it mentions: -Fixed use winflash flash itself error. Maybe the problem is now fixed??!!
