I would suggest System Restore, (in Safe Mode if necessary), to before the audible install.

Option 2: Do a search for a folder called Watchdog and open the most recent file in it with Notepad (ie "Open With" and select Notepad, "Always Use"). Should tell you the offending driver, whatever. Then check your Device Manager. Uninstall driver, reboot, then reinstall latest driver (from Manufacturer) or let XP reinstall a generic one.

Thanks for your input Max.
Unfortunately, I tried to do a system restore and was denied. (I think I ran speed disc right after I installed the offending software.)

But I will try the watchdog trick and let you know how it turns out.

Thanks, and if you can think of anything else I should know, give a shout.
