Explorer.exe application error memory could not be read

This thing has been bothering me despite having reinstalled Windows XP (with SP3). Here are some solutions from the internet:

Using the "Advanced>performance/settings>Data Execution Prevention" within system properties, click "Turn on DEP for all programs and services execpt those I select" then with the add button navigate find explorer.exe and add it, then test to see if you still get the error, [Source] 

This did NOT fix the problem.

I think Carbonite is causing problems after re-installation. It wants to keep restoring stuff when all I want it to do is to backup. I'm going to uninstall it.
