Upgraded to pro CCleaner, pc frozen

Just upgraded to CCleaner pro. I run Windows 18, 64 bit, HP ENVY laptop, i7, ssd, 32gig ram, etc. Can't remember all the specs and can't get into pc for the info.

Pc has been running for 3 hours (hour glass). I've hard restarted 2 times, same thing. It will occasionally flicker. But I still cannot access ANYTHING!!

It won't recognize my external monitors, now.

HELP!!???

Sorry, windows 10. Forum won't let me edit orig post.

Did you use the Driver Updater?

Did you use the Registry Cleaner?

I used the driver updater.

Can't access anything to attempt any type of repair now.
