BIOS beeps when using 3D w/ Gainward TI4600

I posted this thread on the mobo and OC forums, thinking my issue was memory or mobo related. But since it only happens in 3D games, demos, or Direct3D/3DMark2001SE tests, I figure it might be video related. Any ideas?

In the interest of making this thread useful later, I have decided to post the solution to my problem (in case someone else reads this months from now). If you have a low 3.3 Voltage level like I did (2.9-3.0 V), then you'll probably need a higher rated power supply. I put in an identical 420 watt unit and saw no improvement. I doubt I had 2 defective PSU's, so I assume my system demands more power than any 420 can offer. So I threw in a 500 watt PSU and my 3.3 line jumped to 3.28-3.04 V. That did the trick, my BIOS stopped beeping, and I can play 3D.
