I do not find Hibernation to be useful to me so I disabled it.
If you do not use that feature at all, then this would likely resolve your issue. Click the link below which will direct you to Microsoft's support page. Scroll down until you see the two "Fix it for me" buttons. Click the one to disable hibernation.http://support.microsoft.com/kb/920730
This should also free up some space on your C: Drive. I forgot the exact size of the hidden hibernation file, but I think it was 2GB or 3GB. Regardless, the added benefit will be a little more storage space.
