How Can I Prevent This Kernel Panic?

I have encountered kernel panics during normal usage of my iBook G4. I figured out the kernel panic occurs whenever I select a new wireless network in my Airport menu of available networks. Upon restart, I looked at the log, posted here:

I'm not excellent with computers and hardly know anything about coding, but I'm thinking "ATI Radeon 8500", my current graphics card, is what is causing the kernel panic. Am I correct? If so, what can be done about this problem, short of buying a new computer or card?

Hello viper14400,
Still Panicking? If so here are a few things in no particular order that you can check.
See if your Airport Extreme card has a loose connection:
http://www.ifixit.com/Guide/Repair/Installing-iBook-G4-12-Inch-800-MHz-1-2-GHz-A irPort-Extreme-Card/154/1
Remove your 1 GB stick of Ram and see if it still panics:
http://www.ifixit.com/Guide/Repair/Installing-iBook-G4-12-Inch-800-MHz-1-2-GHz-R AM/156/1
From disc 1 of your original install discs run the Apple Hardware Test in loop mode:
http://www.thexlab.com/faqs/aht.html
I believe some programmer from Apple a long time ago put that ATIRadeon8500(4.1.8) in just to
reference a generic video card. Don't really know because I have never dealt with Kernel Panic
before. If you look top left of screen>apple>about this Mac>More Info>Hardware>Graphics/Displays
I believe you'll see you have a +ATI Mobility Radeon 9200+ and I hope that isn't what is giving you
problems because it is integrated to the Logic Board and would require a Logic Board Replacement/
Buy Another Computer Fix.
If nothing else at least my reply will move you from page 13 to the top of page 1 for a while where
someone like cornelius, Lyssa or Niel may be able to offer some help.
Good Luck and Happy New Year,
A

Gratuitous kernel panic on my iMac G3 running Tiger. How can I prevent this

Ok, I know I probably shouldn't have installed Tiger on my G3 iMac so you don't need to remind me. However, it runs pretty good and I hardly ever even see the beachball spinning when I ask it to do something. What I am shocked, shocked by is the ridiculous amount of frequency that I end up with a kernel panic that gives me the 'gray screen' telling me I have to restart my Mac. I have been able to keep this down to a minimum by pointedly only running programs and commands one at a time with a good sized pause in between but even with that I am diappointed with how often it happens. Call me a heretic, but I think it would have killed Apple to stick with their classic OS framework rather than go to UNIX. I would like some tips about things I could do to minimize this occurence above what I already do. It really ***** to have had to reinstall Tiger about 3 or 4 times since I upgraded and have to change up the screen position, dock, desktop, mouse, screen saver, and reinstall all my programs after my iMac has croaked and finally accepted another reload of Tiger.

I'll ignore the major portion of your post which comes across as a rant and try to stick with the title: "kernel panic on my iMac G3 running Tiger. How can I prevent this?"
Kernel panics are usually caused by bad or marginal RAM or RAM that isn't seated properly, or by buggy or damaged software or drivers. In the past, problems with marginal RAM for Macs has shown up when people upgraded to new versions of the OS -- which might fit your situation.
Although your CPU is slow, you have lots of RAM, so Tiger should run OK, if the RAM is not defective. You don't mention how much free space you have on your hard drive. Typically you're going to need at least 5 Gig free to give Tiger breathing room.
Running a system maintenance utility like Yasu would probably also be beneficial:

What does the hardware test for your Mac say about your system? This might help us determine if there is a hardware cause for the kernel panics.

My child accidentally rented a movie on Apple TV. Is there a way to refund the rental if we don't watch it? How can I prevent this from happening? Is there a way to password protect future purchases?

Did you try Parental Controls?
Apple TV: Understanding Restrictions (parental controls) - Apple Support
See if that does the trick: I think there's a way for you to request a password for purchases, but still be logged in.

Regarding Mail: When I return to my computer after it has gone to sleep, my accounts go offline, and are always asking me for the password. THis is very annoying. How can I prevent this?

Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Select the login keychain from the list on the left side of the Keychain Access window. If your default keychain has a different name, select that.
If the lock icon in the top left corner of the window shows that the keychain is locked, click to unlock it. You'll be prompted for the keychain password, which is the same as your login password, unless you've changed it.
Right-click or control-click the login entry in the list. From the menu that pops up, select Change Settings for Keychain "login". In the sheet that opens, uncheck both boxes, if not already unchecked.
From the menu bar, select
Keychain Access ▹ Preferences ▹ First Aid
If the box marked Keep login keychain unlocked is not checked, check it.
Select
Keychain Access ▹ Keychain First Aid
from the menu bar and repair the keychain. Quit Keychain Access.

I was installing adobe reader 10 and it timed out and did not install. How can I prevent this?

I downloaded adobe reader 10. It went through initializing, then started the installation, but it timed-out and was not successfully installed. Is there someplace I can change a setting that is causing it to time-out? How can I prevent this problem?

You can try downloading the full offline Reader installer from

Adobe Flash Player saves large numbers of empty "fap" files to my Firefox and Temp folders. How can I prevent this?

Whenever I go to pages where the Adobe Flash Player "plugin-container.exe" runs "FlashPlayerPlugin_xx_x_xxx_xx.exe" (x's being version number), it causes hundreds of empty "fap" files to save to my Firefox and C:\Windows\Temp folders. How can I prevent this?
Thanks!

Hey, that's great! Thanks for posting back that disabling protected mode in Flash solved the problem.

On certain web sites(with java applets embedded or rich content),sometimes browser hotkeys are beeing used with other functionality (eg.: youtube uses ctrl + tab for sliding between player controls).How can I prevent this?

I would only mention that your definition is incomplete for this -
Contextual selector A type of Style Sheet Selector that
and that it's most often referred to now as a Descendent selector, not a contextual selector. It's basically the same as the Compound selector that you have already defined....

I keep getting drafts of mail I send. How can I prevent this?

Just upgraded to snow leopard...In my mail, each time I send a message it duplicates a copy in my drafts folder.

Would also like to know. Getting annoying!

in Safari, certain
characters like hyphens and apostrophes appear as
black diamonds with question marks.
This has nothing to do with fonts. It usually happens when your encoding is set wrong for a specific page. Panther Safari did not show these diamonds, but just displayed nothing, so people get the impression something has changed, but it really hasn't.
In Safari, I'm using Unicode (UTF-8) as my default
encoding. Is this setting correct?
Not if you keep running into pages with black diamonds. It would be better to set your default to Western ISO Latin 1. The black diamonds will probably go away.

When I exit Firefox, it continues running in the background. How can I prevent this and keep it from happening apparently by default?

I know that Firefox continues running in the background because after I exit the program, I use CCleaner and it indicates programs are still running: Firefox. This happens every time I exit Firefox. There seems to be a default mechanism to keep it running. How can I prevent this?

I have been trying to work on my homework all afternoon, via NAU's blackboard system. I am continuously getting booted out of the system, with an error stating "Data execution prevention". How can I prevent this from continuing?

If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.
If there are specific tasks you need help with:

some sites that use flash (or other issues) dont want you trying to view the site in your browser on an ios device, because they know it will not be a good experience - they detect your device, and if it is an ios device they want you to use their app instead of your browser.

I use chrome on my iPad Air. When I open the ipad it often flashes a page that I had viewed for a second or two and then it is gone. How can I prevent this?

I don't know if you can prevent it at all. The same ting happens to me in other apps - not just web browsers. I realize that since it's a web browser, there might be something that you don't want someone else to see if they use your iPad, so If it bothers you that much, close Chrome when you are done with it.
Double tap the home button to bring put the multitasking display. Find the Chrome app preview window and drag it up off the screen to close it.
