Hi, David, The only wired connection is an audio line out to a stereo amp, unplugging makes no difference. Printer is WiFi, internet is WiFi. External USB drives mounted or unmounted, no difference. No PCIe cards are installed other than the Radeon 5770. No alterations to machine except two additional internal hard drives for backup, which were installed as soon as I bought it. It worked fine for several months. Ejecting them, no change. Problem started out with just a few dots here and there. Over the course of a month it got to where it was hard to read text. Read my original explanation again. Decided to start fresh. Main hard drive was backed up, erased, reformatted and OSX 10.2 was reinstalled fresh from DVD (no change), then updated to 10.5 online (no change). No modifications to Apples installation were made. Booted from a Diskwarrior CD (no change).The dots do not show on the Apple logo during start up (ROM) but do show up at the log in prompt. Only SafeBoot removes all signs of problem. (SafeBoot does not load QuartzExtreme, I am told) I would buy another vid card, but I don't want to spend money on guessing. I have been running Macs since 1987 and have tried all the obvious things. It's either a faulty video card or a faulty Mac, but whatever the fault is, it does not appear under SafeBoot. I can send you images of the problem. Max
Yes it was a typo, I meant Lion 10.7.2, updated to 10.7.5. I have to leave for work right now but I will try the firmware tonight and let you know. If this does not resolve the problem, should I go ahead and buy a new video card? If so, same card or upgrade to Radeon 5870? Are there any Nvidia cards that are OK in this machine? My G4 had a Nvidia card that never gave me any issues. I also have very light video requirements, images and movies only. I do not play any type of games and only have one monitor. I believe simpler is better. Max
The firmare update said it was not supported by my system, for a mac with 10.6.4. I searched for 'Mac Pro EFI Firmware Update for 10.7.5' and I found none! The highest is version 1.5 requires 10.6.4.

Have fun with that!
I have three screenshots I would like to send to you. I think if you see what it looks like it might help. The upload page said click the paperclip, but there was no paperclip. Right now the cursor is blinking and the dots are changing in time with it in the browser text and on your avatar image. Also the menu bar and the dock icons, but only parts of each. Lanes in the vid card? Just guessing. I have no idea what lanes are, but have heard them mentioned.
Going into System/Library/Extensions and removing all ATI Controller kexts and all ATI Radeon kexts and bundles fixed the problem without buying a new $225 card. I was sure that all I had to do was disable whatever files that were not loaded in SafeBoot mode. The problem was finding them. Thanks! Max
Right, I agree. Those .kexts and .bundles were not faulty (fresh reinstall), and I expected the card not to work without them. But for whatever reason, there was some interaction between the card and the files that went away when the files were disabled. And the card still works without them, maybe not full capability, but good enough for camera images, flash videos and websites. Go figure.
