It might be the Mac-VGA converter. I let it run Friday afternoon and it went to sleep (pulsing green power light). This was with a 4GB hard disk that had 9.22 on it.

Somewhere around here I have 2 ATI Rage 128 PCI video cards. One was in my Blue/White G3 before it became a G4. I bought a Rev 2 motherboard with 400mhz processor and video card, the old board was boxed up. The second one is a Rage Orion video card (I think).

If I can find either of those I'll try them out on Monday.
