PPT cannot find cameras

[tavaksai]

Hello Guys,

I recently had to have the motherboard on the DELL tracking
computer replaced (we have an old PPT system) because some
of the capacitors were defective. Ever since that was done, the
PPT software pops up an error message: "Cannot find cameras:
Error -42". The device driver listing shows no conflicts or problems
and the cameras themselves seem to be working fine because I can
receive video streams on the tracking computer using pre-installed
software called Matrox Imaging Products - Intellicam.

Any suggestions on getting PPT software to work again?
