Hi everyone, first time poster here. Was in the process of a system restore to help fix a windows office 365 install problem. Windows told me I had a drive error that needed fixing before I could continue. So I accepted and the PC restarted, now it is hung up on 100% the loading symbol is still spinning. Do I just leave it and hope it finishes?? I have a Toshiba L850 that is nearly 4 years old.
