Hi all. I'm running OS X version 10.4.11 (Tiger). It's a 13" Macbook, two years old, from August 2007. I've recently been having a bunch of problems with it.
First, it drops its wireless connection a lot. Most of the time this happens while I'm playing World of Warcraft, but I've seen it happen even when I'm not. Everyone else connected to the wireless will have absolutely no problem with it, but my Airport icon in the upper righthand corner of my screen will go grey and then connect again, then go grey, connect, etc. I also experience a lot of latency in my connection when others don't (example with WoW... someone else will have 98ms latency, and mine will shoot up to 2500ms or so). Most of the time when this happens my entire computer seizes up. My game skips, my iTunes skips, my mouse skips or won't even move, I can't type or click, etc. Additionally, I've had it happen even when I'm connected to the internet with an ethernet cable with Airport turned off, and my internet connection will die completely until I restart my computer.
I've had problems with this computer in the past as well. About two months after I bought it, it wouldn't boot up and I had to reinstall the operating system. Then a year after I bought it, my motherboard crashed, and they couldn't really tell me why it might've happened.
Second, I've had two kernel panics in the past two months. The first one was July 18th, 2009, and the second one happened just about half an hour ago today (Sept 4th). The panic.log is as follows (both dates are included):

I have absolutely no idea what any of that means. If anyone can help me, that would be great.
I've already run memtest, and I've already run the hardware diagnostic test that comes on the CD that came with my computer (both the short version that takes about 30 min, and the extended one that took about 3 hours). The memtest said everything was fine, and Apple's hardware test came back saying "No problems detected." ...Which I don't believe for a second; clearly there is a problem.
This combined with the problems I've had with this laptop in the past have caused me so much frustration with this computer that I finally just bought an Acer laptop a few weeks ago. I'd still like to figure out what's wrong with this one, though.
Any and all help/insight anyone could give me on these problems would be greatly appreciated.
