System Crash while using Browser Camino

[jcapp1]

I have a PowerMac G4 using system OS X 10.4.11 while in my browser Camino I ewill have a system crash after about 20 minutes of use. I will restart and then a continues crash every 5 minutes. There is no error code.
I am running Camino 2.1.2. Same thing happens when I am running Safari. Any help would be greatly appreciated.

First thing I'd look at is the RAM. How old is it? Does the system report the correct total RAM installed? Can you remove one of the sticks of RAM at a time (with the Mac off) and see if it crashes?
