I have fast boot enabled so shutdown and subsequent boot takes very little time like it should however when I restart my PC, the subsequent boot time is enormous, sometimes 20 minutes+. It keeps showing the Windows logo for a very long time, then shows a blank screen for a very long time and finally shows my lock/login screen.
I have Windows 8 Pro US 64 bit
Lenovo Ideapad Z580 with NVidia Optimus and Intel Graphics 4000 and 16 GB RAM.
Things I have already tried: Doing a clean boot with only essential services on and all startup items disabled. I don't think it has anything to do with start up items or system services.

ok, I also think you have HDD issues. I checked the traces and the high CPU usage is caused by the
CI.dll (Code Integrity Module)which hosts SHA functions. Windows calls those SHA functions to verify the code integrity of System files.This is during boot. During shutdown the same happens again. This causes other delays (GPO, Offline File cache, stopping Google Input helper at shutdown).
So download the diag tool for your Hitachi Travelstar 5K750 750GB and look if the tool detects any kinds of issues.
