That is just my signature. nothing wrong with the system info tool, but you don't have to download it if you don't want to. That link will help you just fine. System restore is fine, you just may have to redownload updates, etc. it removes what you've done up to a point in time (whenever the restore was created). Thought you already did that though?
Google is very helpful. I made a slight joke that if you don't want to search google, just ask sevenforums, as that is a way to make easy reputation on the forum. In other words, people who ask the easy questions often give easy reputation that we "experts" don't have to work very hard for.
