the disk structure is corrupted and unreadable

Hi, I'm using Windows 7 on an SSD. Since last (2/20) Windows update, the system has been acting strangely with logging mouse clicks. Processes are low, doesn't look like anything running in the background. When I tried to do a system restore to before the update, it told me that "the disk structure is corrupted and unreadable". When I tried to fix, since it's the c drive, it said I had to schedule it, which I did, and nothing happened. Rebooted myself, and doesn't seem to have tried to do the restore.

Any suggestions?
