Someone unfamiliar with Windows installs this OS onto a laptop. They may not know about drivers for the laptop's motherboard or other tweaks the laptop maker made to get peripherals working. The clue in you post is "XP Pro" which is not the usual OS.
What I've found is the painless upgrade to Pro is to use the laptop's supplied XP Home install then let Microsoft upgrade it to XP Pro. This way I don't have to hunt down motherboard or other drivers.
In closing, some older laptops will need a BIOS update to function. Keep in mind that Microsoft does not check for either proper motherboard drivers or BIOS versions.

The problem I am having is that my Toshiba Satellite A75-S206 laptop freezes up after the external modem answers a phone call. The voice mail program senses a call, announces the caller ID, answers the call, but while the greeting is played the computer freezes up completely. I have to turn the computer off and cold boot.
I have tried several modems and voice mail programs with similar results. Using a modem with a separate power supply the computer froze up on every call. With a USB modem, it froze up on every other call. Since the computer doesn't have a place to plug in a serial cable, all efforts to date have been with the USB connections.
My guess is that there is a voltage spike that is causing the problem but another intelligent sounding person suggested, without providing a working solution, that there is an interrupt conflict. The operating system is XP Professional SP2.
I am looking for an explanation of why the computer is locking up and a known solution.
