Hello ineedhelp2012 and welcome to Seven Forums.
It's dangerous to use registry tools. They can cause more damage than they fix. First thing I'd try is using a system restore point to return my computer to a date/time prior to when the hibernation problem first appeared. System Restore
If that doesn't work or if you don't have any system restore points I'd run a System File Checker scan from an elevated command prompt (option two, this tutorial.) If any problems are found run the scan 3 times rebooting in between each scan. SFC /SCANNOW Command - System File Checker
You could also try turning hibernation off, rebooting, then turning it back on. Although if you don't use hibernation you could leave it off and gain some additional hard drive space almost equal to your installed memory. Hibernate - Enable or Disable
