[G4] Video card conflicts

[Kevin Willis]

I have a 400 Mhz Gigabit G4.  When I bought it (used) I put a PCI ATI 
Radeon 7000 video card in it.  I left the 16 mb AGP card that came with 
the system in it, although it is not being used.  I haven't had any 
problems with the system until now.  I installed a 1 Ghz Sonnet Encore 
card last weekend, and I have been having a lot of trouble keeping this 
thing up and running.  I keep having apps. lock up, kernel panics etc.  
I am wondering if there might be a conflict with the CPU dealing with 
the 2 video cards in the system.  Could that be the case?  Should I 
pull the AGP card and leave that part of the case open until  can 
afford a good AGP card?

BTW, I am running OS 10.3.5 with 1 Gb of RAM.

Thanks--
