I have a laptop with Windows 7 Enterprise. If I leave alone for an hour then the laptop freezes. I have checked all the power options so that nothing kicks in (like hibernate, etc.) after an hour. I finally just checked my event log after it happened again today, and there is only one entry, about an hour after I stopped using it:
The disk defragmenter successfully completed defragmentation on System Reserved
Could that be the culprit? If so, what should I do to fix it? If not, what else can I try?
In case this can help someone else, I was able to disable defragmenation on just the System Reserved disk. Now a defrag can still happen on my C: drive.
