For the last one week my windows 8 laptop doesn't shutdown or restart.
I tried chkdsk, it says no issues. Tried SFC, But no luck. It just said 'Windows Resource Protection found corrupt files and successfully restored them" - But still No shutdown or restart.
This happens the second time - even after I completely formatted C drive and a fresh install of Win 8.
Because the problem's so recent, and because so many things could cause this issue, a Windows "System Restore" would be the first thing I'd try - have a look here for full instructions. Don't worry about losing e-mails, photos or other personal files as they won't be affected.
