If your using Geforce 2, you might consider the "Frogmaster mod" When a geforce2 is installed in a p3v4x the agp slot is not provided enough power. It seems to be a voltage regulation issue on the mobo. I had some cold boot issues with my AIW Radeon after adding a dvd drive. Unplugged my second HDD problems went away. In my case too many devices for a 235 watt supply. Before taking a solder gun to my p3v4x, I'm going to upgrade to a 300 watt supply. Good Luck.
