jcortes, If you have a Dell Dimension system having
a factory installed Creative Labs Audigy2 sound card try this:
Open the MSCONFIG utility (Start/Run type in MSCONFIG click OK) and deselect (uncheck) the /l:ENG entry from
the STARTUP tab, click Apply, click OK and restart your computer.
The link below expains the /l:ENG entry.

If none of the previous suggestions solve the problem go to the link below and download & run the "System32 Folder Opens Upon Boot" Fix. It's Number 260 in the right side column. It has worked for others.
