Thanks, i will do that !
Any recommendations for a good Driver cleaner prior to installing the Blockchain optimized drivers ?
I know the Radeon software is supposed to remove the old ones but after installing about 6 - 7 driver sets i am sure it's not all squeeky clean.

i am even contemplating to format the PC and start over from scratch, but i would like to attempt a proper cleaning if possible to save a lot of time.
