Loss of video signal with Geforce 2 Pro - Help

[Fuelrod]

I have a Geforce 2 Pro 64 Meg I am trying to use with an Abit BH6 motherboard. When I start a 3D application the monitor will lose the video signal and go black. I have to reboot the machine to get it back. I'm thinking I don't have enough power on the AGP slot to drive the card. Has anyone else had problems with the BH6 and the Geforce 2 cards. Also, does anyone know how to increase the I/O voltage on the BH6. I'm thinking this could help the problem.
