Hibernation stopped working after prog install & PC freeze

After working flawlessly for a couple of years my hibernation now doesn't work: when I choose it, the screen goes blank and there is some hard drive activity but then it stops and just returns me to the screen I was on. Sleep still works perfectly.

Two things happened before this: I installed a backup program called ShadowProtect (since uninstalled) and I had a couple of PC freezes due to a bad piece of software, which meant I had to a hard reboot.

I ran Chkdsk at bootup to make sure the drive was all OK, which it was. I've also disabled and then re-enabled hibernation. I've looked at Event Viewer but I can't find any actual errors, and am not familiar with the program.

Where do I go from here ?

Did you try system restore?

Try a Repair Install.

If I run powercfg after a failed hibernate attempt this is all I see:

C:\powercfg -lastwake
Wake History Count - 0

Repair Install

I'd like to explore other options before doing that ...

I'd try the repair install as recommended by quickdraw2011.

Some other things you can try:

• Make sure you do not have an un-saved theme.
• run "powercfg -energy" CMD and analyze the report.
• Make sure something in BIOS did not change preventing Hibernate.
• Re-install drivers, especially the video driver.

If you don't have backup images consider using those going forward.
