Yeah, the only wear and tear that would happen is if you pressed the quick restart button on the case, completly resetting the PC straight away since Windows woudn't get a chance to save settings.
Going to Start, Shutdown, and then to Restart Shouldn't bother it, unless something is actually wrong with the hard drive before hand, which shouldn't be a problem.
If you are that bothered though, go to Start, Run, and type:
This will scan for any possible errors on the machine that might have built up
EDIT: I forgot to mention the final step. I dont think it'll fix errors unless you tell it to. This can be done by typing this in run as an extra
this will set Windows to fix what it finds. Also if the computer is running tasks it needs, it'll ask if you want to run it after a restart since no processes will be running then.
