Video Card or what else?

post #1 of 11
Thread Starter 
If I might ask a few questions about this, that would be awesome.

My G5 seems to have issues that may be the video card?

- The screen gets lines in it
- The screen will get blotches in it. The windows get distorted and weird.
- It doesn't always come up on start up. It appears to be running, but nothing on the monitor (30" Apple)
- Most of the time on restart it comes up, sometimes I need to do this 2,3 or even 4 times.
Less times, the longer I wait.
- Watching video's / movies online causes it to freeze
- Sometimes when working in any of the drawing applications, there will be blotches of colors showing up
that I can get rid of by resetting the window size. These do come back the longer I'm working in that application
and the longer my Mac has been on.
- Fast movement of the mouse or going into the corners can cause this to happen as well.

Your thoughts folks?

I had similar issues with a G5 iMac several years ago ... it ended up being the "logic board" that had to be replaced.
"They" would not tell me what it was on/about the logic board that was faulty. It does, however, contain most of the components of the computer, so it could have been any number of parts (In fact, I believe the video card was integral to the logic board on that iMac... so it could have been the video card.)

In short, if that's your problem, it's a pricey fix... I just ended up spending a few more $ and got a new C2D when my G5 acted up... (in 25 years of owning Macs, that's the only one that ever had problems.)

Now, if you have a MacPro G5, you can replace the video card by itself... maybe find one used/cheap online and try it out ... see if it fixes the problems.

Thanks for that. The only interesting thing here, is mine is a desktop unit, so the video card and logic board I believe are two different pieces that can be replaced as needed. That's not to say it still won't be expensive

iMac = desktop = video card soldered to logic board.

MacPro = desktop (floor? ) = video card easily replaced.

Since you've said the same, logical thing that I would say but apparently that's wrong, I feel obligated to correct you by saying that some iMacs have their GPUs on MMX (or whatever the frick it is) cards and those can be upgraded/replaced.

newer ones, yes ... but if i recall correctly, the G5 iMacs were not so constructed (at least I KNOW the G5 iMac I had had it soldered to the main board.)

Ok, so if it is the video card, is there an up-grade from the Radeon X1900 that I should consider?

If it is, you'll have to get a new computer or buy a logic board and swap it yourself, since Apple doesn't do repairs on G5s anymore. You can't upgrade from whatever GPU you have right now if you buy a new logic board, as only the logic boards that work with your model will, well, work with your model.

Ooops, sorry this is a desktop pro and the video card is replaceable by itself, and I'm hearing that, that is likely to be the issue.

So I'd like to know if there are better Video cards I should consider, seeing I'll be replacing it.

OH! You have a PowerMac G5. Sorry, got confused; King has the iMac G5.

Okay, um Hoo, I have absolutely wretched short- and long-term memory, but I recall the X1900 to be absolutely terrible in terms of the performance/power draw/price ratio. Am I right with that?

You cannot get a better card than that. All Mac Pro cards are EFI and PowerMac G5 cards were OpenFirmware. You can, however, flash a PC Quadro FX 4500 card (because they're cheaper) and use that in your PowerMac, but that's somewhat dangerous, sort of silly at this stage, and I don't know how its performance stacks up against the X1900 anymore

You'll have to check on the slot that the card goes into ... AGP?, PCI?, PCIe? (I just don't recall) ... find an appropriate card THAT ALSO HAS DRIVERS FOR WHATEVER VERSION OF OSX YOU ARE RUNNING! ... As long as it meets those two requirements it'll work ... so yes, getting something newer would be better ... finding drivers for something different than it shipped with would probably be the tricky part.
