Windows 7: Can't Open my documents in W7

Hi
I have Windows 7 64bit and downloaded some updates today and Windows 7 SP3. Since then i can't open the "My Documents" folder i had on my Desktop. I don't get any messages. It just won't open.
Also on my taskbar i have a shoctcut that shows my Libraries.
I can access the Music and Video Libraries when this opens. But not the Documents or Photos one's. I get a click sound, but they won't open.
I also can't save any picture project am i am working on in the photo's libray. It just says i can't save there.
Any ideas??
Thanx

Well if you downloaded SP3 thats the problem; there is only SP1. Im only kidding, I assume that was a typo
Go back with a sytem restore a few days before the problem downloads.
System Restore

Then put each update in separately and test. Once you are sure that it is not the upadates, make a system restore and install the SP1, again, and test.
