Could updates be my problem?

I am having trouble with a new install of XP. Everything works just peachy

until I install the updates. When I try to go to all programs under my start

menu I get an error that says explorer needs to close. I send the report and

the same thing happens each time I try to do this. I restored my machine to

the original date of the install, before updates, and everything was fine.

This problem is also effecting my ability to see my digital camera. It will

not load the drivers even if I go to the Sony web site and download them

there. Anyone have any advise on what this could be and/or how to solve it?

Thank You Sean
