If you are having lockups, blue screens, error messages...etc. Many times the cause is a corrupt driver. Microsoft has a tool already installed in Windows XP called Driver Verifier Manager. This easy to use tool will help you identify the cause of a driver problem. Here's how to use this tool:
1.Go to Start>> Run. Type in: verifier [Enter] or Click OK.
2.With the Select A Task page open, keep the default setting "Create Standard Settings". Click Next.
3.Choose the "Select Driver Name From A List" option.
4.Select the driver files that you would like to verify by checking the checkbox next to a driver file.
5.Click Finish, then Reboot your system.
If you encounter a Blue Screen along with an error message on restart, then one or more of the selected drivers are a problem. If your system boots normally, then you have no driver issues with the ones that you've selected.
