The Indexing Service seemed to have calmed the issue, but it looks like you have some power problems.
It looks like we are going back to the
post where I said that Sleep Mode delays interaction with the desktop, which could mean a Sleep mode failure.
Have you ever had any 'serious' malware, viruses, or spyware on your computer? The reason for knowing this is because the host process for Sleep mode may have been modified and not fixed IF you have had severe threats in the past. If this is the case, then a minor fix can be instituted.
Other side of the tracks, we will diagnose and solve Power Options. I am sure we can change a few settings and may be that was the issue.
Let us not confuse ourselves, go ahead and let me know if you had any past severe threats and we will then move on!
Edit: Please see this page for the potential first fix. The issue I have saw here is that sleep mode may have been disabled if Hibernation is in a reduced state. It seems as if the hiberfil.sys has reduced its own file size on your machine. We need to turn hibernate back on all the way.
