Quake III will continue to run even into Intel and later OS versions with the UB update.
Your machine is limited to OS X 10.5.8.
Quake III is fine in 10.5x.
BTW, the processor upgrade could be the reason for the failure of the AHT.
I'd suspect graphics card and disallow the AHT results.
What graphics card do you have?
I have an ATI Radeon 9800 Pro Mac version vram 128 MGs of VRAM, Chipset ATY,R350.
I was thinking of trying to reinstall the ATI driver, or a more current version but I'm not sure they are still around, or where to find it.
So you feel that both Eudora 6.2.4 and Quake III will still function properly with Leopard 10.5.8?
Thanks for your input. (I think you've bailed me out of a jam a time or two in the past and I thank you in advance for your time and expertise.
I'd strongly recommend replacing the thermal compound on the Radeon 9800 Pro. It could very easily be a simple matter of lack of cooling which is causing your issue.
I have a tutorial here:
Use Arctic cooling MX-4 compound.
As for drivers or ROM updates, if the card is a flashed one, don't bother with the firmware. All ROMs are the latest firmware.
In Tiger, there is a retail driver update that you can try:
No updates needed for Leopard.
Eudora should be fine:
Quake is fine. This coincides with my observations:
The solution that you set out for me worked flawlessly.. (replacing the thermal compound on the GPU with Arctic MX-4)
I have had my Mac on for about 6 hours and not a hint of any artifacts or video noise of any kind...
Thank You one more time.. (before it would show up in 15-20 minutes)
PS: I did the repair myself too.. (not a big deal for most, but a big deal for me. )
I'm sorry to report that after a week or so and after working on my Mac for a few hours 4-5, I do find some artifacts sneaking back into my display.
My new question is, where can I find an equivalent or better Graphics (Radeon 9800 Pro 128 MG) card for my Quicksilver machine for a reasonable price from a reliable dealer or seller?
Or, if you have any other suggestions to try to repair this one I'm willing..
Like I said it works for 4-6 hours than it starts getting funky again.
I still feel that you were totally on the right track because for a couple of weeks or more it was smooth sailing..
Thanks Again japamac & others for you helpful suggestion.
Are you using the stock fan on the Radeon? Those things do wear out easily.
That would also explain the initial improvement and slow degradation.
A third party fan is of definite benefit. A Zalman VF700-Cu or VF900-Cu will cool like crazy.
Or, you could put the money into a replacement card.
eBay has some 9800 Pro cards, and your QS can use flashed 9800 XT, Geforce 6800 GT, or Geforce 7800 GS cards.
The 6800 GT has long been a favorite of mine.
If you can't find anything comfortable on ebay, contact me via my website as listed in my profile.
