Dr. REBOOT Problem, my Blue & White G3, 350Mhz I think, is connected to a Dell 19" flat screen monitor. Has been working fine until I needed to use it this week. I,m now getting a message on the monitor saying I have no VGA signal. To test the monitor I hooked a pc to it and came up fine. Am i correct in assuming the most likely problem is the video card? The G3 powers up, at least I get the start up Bong, but I have nothing else. Is there anything else possibly wrong? I don't want to spend $$ on a new card just to find I have other issues. Will the video card from a PowerMac G4, M8493, fit & work in the B&W G3? Need to keep the G3 running as I use it for all household finance & tax info
The video card for the G4 is probably an AGP, you need a PCI for the G3. See the pic below.
Does the monitor blink or click or do anything doing startup other than no VGA message?
To test the G3, boot it up, give it enough time to finish. Alternate hitting Command-Period and then the Return key a few times to dismiss any dialogs that may have come up that you can't see. Next either push the power button on the keyboard, or hold Control and hit the Eject key and release. You should hear the computer Bonk or whatever, then hit Return. If the computer shuts down it is successfully booting up and it's probably just the video card. Those key combos bring up the shutdown dialog, try it on the working G4 to see what it does.
Well, tried what you suggested. When I hit the power button to power up the G3 I got the usual boot up Bong. Heard drives spinning up, etc. After I let it sit for several minutes & I hit the Control period & enter several times alternately. Then hit the power button & Nada. never got any further sounds other than drive noise Tried Control period enter some more and then Power button again. Finally had to force shut down. ????????
Do the Command-period and Return before hitting the power button on the keyboard. That is just to make sure that there are no dialogs on screen. Then after that hit the power button then Return.
Did you try this on the working G4 to see what happens?
I've run across Macs that wouldn't boot because of a bad battery. It was running okay but then failed to start the next time they used it. The UPS has nothing to do with booting if it has a bad battery BTW.
Also try pulling then reseating all of the RAM, video card, and any other add on cards. I've seen older machines not boot because of oxidized connections.
