ArcMap 10 SP2 causing crash on startup after using arcpy

We just installed ArcMap SP2 onto all of our computers two days ago, and it was working fine for a little while. Then it would crash once in awhile, seemingly randomly. After testing more scripts in ArcMap, most MXDs would crash when attempting to open. The only MXD that would open properly was the one MXD that I had been testing my scripts on. Now it has gotten to the point where no MXD will open without crashing, not even a blank MXD. Is there a known solution to this?
