Safari 2.0 crashing after Tiger installed.

Question

I recently installed Tiger OS X 10.4 then did the Software Update to 10.4.8 Combo.
Issues:
I had downloaded and installed an IP blocker and "list manager" called PeerGuardian2 which, while it provided security, was so bad it even blocked Google and amazon. Perhaps I wasn't using it correctly and that's another issue. Anyway I experienced problems with the mouse and erractic behavior on the browser which showed up on the screen as "bits and frags", then usually followed by a frozen mouse and system crash.
My first solution:
I deleted PeerGuardian2 and did a reinstall of Tiger and reinstalled the update.
So far so good. Until today I had another crash using Safari. And after reinstalling Tiger, I noticed logging online with Safari was very slow to no go. But once I got it going, it loaded normally the next time. Then later on I had another crash.
I am currently using Firefox to start this thread, which, sofar, runs smoothly.
If anyone has had any experiences like the above and have solutions, pertaining to Safari 2.0 crashes, I'd like to read them. I am investigating the possibiltiy that my hardware may be too old, or slow. That I need to install more RAM, and maybe a fast processor upgrade card from Sonnet. I'm running my G4 with the processor it came with that ran on system OS 9. Until the Panther and Tiger releases it worked fine. I haven't needed that much memory or speed, but with new OS rollouts, I may now.

Hawaiian_Starman,
It would appear that the Knowledge Base article trumps the comments in the article that I cited, and due to my limited indirect knowledge of the repair process I will defer to Apple.
but, I also remain confused...What repairing permissions does and whether you should do it, by Dan Frakes says: When you use Apple’s Installer utility to install software (such as Mac OS X itself or an OS X update), the installation package (the .pkg file you double-click to begin installation, or that Software Update downloads in the background for an automatic installation) generally leaves behind a receipt—a smaller Mac OS X package that includes information about every file installed, including the permissions each file should have. This receipt is placed in /Library/Receipts. When you run the Repair Disk Permissions function, it examines the receipts in the /Library/Receipts directory of the disk being repaired...
Thanks for your Safari expertise.
