Hello, Recently my daughter( 17) seems to have tried to upgrade her Win 7 to Win 10. She came and said that she got a blue screen with a smiley that would not go away with a WDF-Violation on the screen. She powered it on and off a few times and now she has nothing but a blank black screen. I cant seem to even F8 anything to come on the screen. She has none of the restore disks etc... Is there any known downloadable repair disk/fix for this that I can perhaps burn a disk and load it into her CD drive will boot and repair?
