The drop seem having damaged the original video card, and/or its slot. (odd, because other things should have been more fragile...)

Any ideas? >From your pictures with the new card, it seem to me the hardware (card and slot) basically is working fine: if they were damaged, the screen would show a problem everywhere. Your issue, to me, seem in the software level: maybe the drivers, or the card's firmware, or its compatibility with your Mac and OSX. I mean: - In picture 1 (after replacing video card 1) only icons and menubar are corrupted - In picture 6 (dock), only Dock's icons and menubar are corrupted - In picture 5 (word), everything looks corrupted - probably because Word uses its own routines to redraw everything (this is usual Microsoft attitude) and it clashes with OSX. So, it seems something is wrong with a part of OSX system redrawing, maybe Quartz. Are you sure you new card is "made for Macintosh", and not a PC card re-flashed for Mac? (if it was cheap, it's likely it is). If it's reflashed, this could explain the odd behaviour, due to not complete compatibility with OSX redrawing routines. I don't know if you can update the card's firmware. If it's possible, you could try. > I don't think the video ram difference is > causing these thin black lines however I am no expert AFAIK, the 128 MB Vram should be fine. It's more than enough for regular 2D use. If the Vram itself was bad/failing, image problems would appear anywhere, not just in selected part of the screen. > Thanks to anyone who may have an answer, as it is difficult for me to > get help where I am now located. Better thing should be trying a graphic card from another (working) Mac, to be sure it's the card and not something else. But I imagine is not easy finding one. You should try to "reset" your Mac, I mean: - resetting the PRam (boot holding Apple+Alt+P+R keys until your hear three "bongs") - resetting the Cuda/PMU switch (when Mac is OFF), see: http://support.apple.com/kb/ht1939 http://www.flickr.com/photos/mac_users_guide/3540352097/ Also, as Dan said, check the card in System Profiler, and run an Apple Hardware Test CD check. After following these steps, you should find some info and/or improvement or meaningful hints. If the problem is stil present, post your findings here (together with your OSX version and exact G5 model) and we could have a better understanding. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
