Like I said in my first post, and never got an answer to. Did you install any software prior to you noticing the system restore issue? Do you suspect your security software? Have you read event viewer for any errors?
If you have tackled all that, then my next course of action would be a repair install. Because at that point something is wrong with Windows. But before you do that try a sfc /scannow in the command prompt. Run command prompt as Admin.
