Can System Restore Damage my pc

Basic restore feature isn't suppose to damage the OS, other than to bring it back to a prior date. HOWEVER, if you have a real problem either s/w or h/w its not necessarily going to fix it. Maybe, a s/w one but certainly not a h/w one. I don't know why you needed to even do a system restore which maybe the crux of your problem. Any restore point is just previous stored data on given data, which sits until used. That of itself shouldn't be a problem but if it so happens to become corrupted by some process just sitting there then that relates outside of system restore. If the access of system restore point becomes corrupted *during* the process that suggest yet another problem. For now, you didn't state why you wanted to do a system restore. I *ASSUME* you're using the OS system restore point as well not one provided by some 3rd party s/w. However, again some 3rd party s/w may start a system restore point using the OS based one. For now, you haven't provided why you wanted to do a system restore and I refer to the beginning on my post for possible source of error.

In my experience OS system restore does work, provided no "hard error" or such is present. Often enough some wayward install or user induced task caused a problem. The whole purpose of the restore feature is to return prior to such errors. This isn't a super magic trick but it is one that can be relied excluding what I explained above. Again, I don't why you needed to do a restore in the 1st place. I didn't gleam any info on why from Yahoo answer post.

However there is a lot of malware that can corrupt the OS and most of today's users can't recover so in effect that's a damaged PC for them.

And so far, I've yet to find system restore to damage a hard drive. Given the malware and how iffy power supplies or other hardware issues can exist it would be possible, some day, some where to run system restore and at the same time for the existing conditions lose a drive but on it's own? No.
