I had a similar problem with a B&W upgraded with xlra G4/450. After many frustrating tries I removed the Ultra wide SCSI PCI card, disconnected the ZIP and second HD, replaced the USB keyboard with ADB keyboard and mouse, and removed all RAM except the most recently purchased stick. I then held down the two buttons on the mobo for 30 seconds each. The system booted fine though I had to reset date & time as expected. Started replacing things I took off - putting them back one at a time over the next week, turning the unit off and rebooting several times after each reinstall. Everything went great until I started reinstalling the memory. Turned out on memory stick was bad and one memory socket was bad. The computer would boot with one good and the bad memory stick in good sockets (Profiler didn't show bad memory), but it acted exactly like yours when either a good or bad stick was in the bad memory socket. I'm just not going to use that socket in the future. I still haven't replaced the USB keyboard and I have not used the second USB socket on the back since pulling everything off.
