Cannot save anything

Ever since I got the free upgrade package to Windows 7 home premium 64bit I can no longer save anything from anywhere even if im just typing up a word document and hitting save as. As soon as I do Windows says the program is not responding and restarts it. I would post a screenshot of what it looks like but I cannot even take those since it tries to save them and then closes down. I was wondering if anyone else is having this problem at all and knew of any solutions?

%windir%\system32\eventvwr.msc /s

Copy and paste to start menu search box, hit enter. Check for anything of interest.

I copied and pasted like you said, and it came up with no critical errors only a warning from microsoftword that happened within the last hour so it was most likely when it stoped responding after I tried to save my school paper

At the bottom of the error is a link to look up information about it at Microsoft. Sometimes it proves helpful.
