My G4 Mac always freezes on boot after gpu upgrade.

My Power Mac is https://everymac.com/systems/apple/powermac_g4/specs/powermac_g4_400_agp.html.

It is fine with original card “rage 128”, I upgraded card to “ATI 9000 Pro for Mac”, but after that, always freezes after boot.

Here is picture. I can’t do anything, but I can move mouse cursor.

Do I have to anti-upgrade patch like powerlogix or newerTechnology?

Have you tried booting up in safe mode by holding down the shift? It could be an incompatibility with a system extension.

Did you install the specific Radeon 9000 drivers?

Generally speaking, this is required for proper operation. There’s 9.x and 10.x version on that image if I recall.

Oh, thank you so much!!!! I didn't know that... I installed ATI driver first and I plugged the card, it finally works!!!!!!

Oh that is good to know! Thanks! I was watching this thread because I had ordered the video card for my G4 Cube. I will download the drivers to keep handy.
