Yesterday was odd, was running OneNote the full program and it sit for about 15mins. When I came back to it, the whole screen was frozen. Couldnt touch it, nothing. Had to hold the power button for about 30 secs for it to shut down the machine. Never had any freezes ever and wondering if this is the machine or OneNote that most likely caused it. A friend of mine told me that One Note the full program has a tendency to lock up, is this true? If so, then ill stop using it and just stick with the app. Also, because I did a hard shut down, is the SP3 like regular computers where if you do this, you need to run a disk check on the drive and check for errors?
