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

[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!!???
