Dont necessarily blame P5 immediately, XP itself has some issues with processor use. Try going (if you havent already) to the microsoft site and having it evaluate your system for necessary patches, upgrades and service packs. In particular get the WinXP SP1. Dont get the driver upgrades, get them from the OEM sites (Microsoft may be behind a bit). Solved a number of my problems that I had been blaming CL for. Scarab<-"give blame where blame is due"
