Computer Hangs on Shutdown/Hibernate/Sleep

I have an HP 2000-2b22DX Notebook PC running Windows 8 64-bit. When I set my computer to sleep, shutdown, or hibernate, it won't actually do so. Programs close (if I'm shutting down), the screen goes black, but the wifi indicator light does not turn off, the fan doesn't stop running, and the computer doesn't turn off or sleep. The only way to bring it out of this state is to let it run it out of power or to hold the on/off button.
When it turns back on, a message telling me that my 'PC ran into a problem that caused it to restart' comes on and the following files are implicated:
C:\Windows\Minidump\013113-15453-01.dmp
C:\Users\AppData\Local\Temp\WER-56890-0.sysdata.xml
C:\Windows\MEMORY.DMP
It originally started doing this about 30% of the time, then maybe 60%, and now it's every time.
I have tried updating my BIOS and, while it helped temporarily, it didn't stop the problem. Kaspersky did not indicate any problems either.
