The other day it was taking a good 15-20 to boot. I did defraged, disk cleanup & used the anti-malware/virus tools suggested in case that was the reason.
Boot time has improved from 15-20 mins to 2-4 to boot, but still experiencing skipping/garbled audio, slow overall, still lost Admin priveleges & can't reset those (even in safe mode)?
I'm at a loss at this point...and way over my head. Your tech know how is needed greatly.
