When I open the python window in either ArcMap or ArcCatalog (ArcGIS 10.1) as soon as I press a key it freezes the entire program and it crashes. It doesn't produce any warning, error, or pop up with info afterwards it just crashes. I tried searching for similar problems through the forum but none of their solutions worked. I installed Service Pack 1 and that didn't solve the problem. I can use IDLE and/or PythonWin to import Arcpy but some custom python tools won’t work. Some of those tools crash it in the same way. Has anyone experienced anything like this or have any idea on how I can get python window to work for Arc 10.1? (I have also tried uninstalling and re-installing ArcGIS 10.1)

I recommend checking whether you have another version of Python installed, besides the one installed by ArcGIS for Desktop.
From the Comments it appears that you did have another Python installed on your computer i.e. Python 2.7.5 installed in addition to Python 2.7 for ArcGIS, and once you uninstalled that everything began to work perfectly.
