emac takes craps

hello all,
i am very new to the mac thing. my friend recently donated his troubled 800mhz 1st gen emac to me and i have been giving myself a crash course (literally) in non pc computerland. i was wondering if anyone could help with my issue of abrupt safari closeouts. In fact I had to reload this forum 4 times due to the browser closing down on me. i installed a clean 10.4 os on it and it has improved other issues such as not being able to shut down the computer and some lockups, but i still have the browser issue and occasionally will get a fatal error w/ the kernel where i get info blasted and locked up on the screen.. please help! i really want to love macs!/
