My PowerMac G5 won't recognize the monitor that goes with it

When we try to turn the desktop on it sounds like its starting up, but the monitor stays black and the power button flashes 3 times and then goes solid for 10 seconds or so before flashing 3 times again, repeatedly. It's not responding to anything and won't turn on completely. Any ideas as to how to fix this issue? We were able to find out that the flashing possibly mean the desktop does not recognize the monitor as compatible but it's that monitor that came with the tower so we're not sure how this would have happened...

Check your video cable ends for bent pins or debris, then make certain that they are plugged in straight and tight.

SOURCE: Apple PowerMac G5 Mac Desktop

Yes, that is a major factor. Because the files arent actually kept on the desktop, so when you boot it, the machine has to" remember" where that content is actually stored. You should also defrag the hard drive with DISK UTILTIY.

MAIN DRIVE/APPLICATIONS/UTILITIES/DISK UTILITY

You can also check the space left on the drive. It should state at the bottom of the window when that volume is selected. Or you can also click on it once and hit the apple and "I" key..

APPLE+ I also know as "get info" from the top file menu. If you do a considerable amount of downloading, or if you have a massive itunes folder and you are saving that to your internal drive and not an external, you operating system has to weed through all that information. If youre getting spinning beach balll as well, I'd recommend install more RAM modules.

Hope this helps, keep me posted.

SOURCE: My eMac doesn't like to restart after being put to

I know emacs have had there times and this might be the cause for yours as well. Do this: turn the mac upside down take off the memory cover from the unit using a screwedriver now you will see 2 round capcitors there check to see if there buldging at the top or leaking for the bottom. Now not all caps leak they just buldge. If this is the case you have a couple options here 1. repair it yourself 2. take the logicboard out of the system (a lots of work) and log on to www.badcaps.net this dude will repair it for $75.00 plus shipping Thanks

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

SOURCE: PowerMac G5 with dual 2.7 processors powers on but no video

There are seven diagnostic LEDs near the memory banks of this model: six in a tight line between the edge of the logic board and DIMM bank 1, and the seventh just underneath DIMM bank 1 and slightly more inboard. Please tell me which of these LEDs are on and I will tell you what they mean.

SOURCE: power mac g5 shows terrible

None of the parts are usable in any other machine.
The coolant from a liquid-cooled G5 PowerMac is toxic. If your G5 is leaking, disconnect the power cord IMMEDIATELY. Flush any skin exposed to the fluid with water for at least 15 minutes.
If you want to glove up and extract your hard drive from the machine so as to save your data, do it carefully. Other than that, my recommendation is to bag up the unit and handle it responsibly as toxic waste, using the same guidelines your area uses for antifreeze.

Video jitter on youtube on power pc

Try using the browser Google Chrome, it has flash built in and it is a bit faster.
If this doesn't work, you'll have to kill some programs to get more processing power. Press and hold the command key, and then tap tab while still holding command to cycle through your running programs. Let go to stop on one you kill, and then press Command + q to kill it. Do this with as many programs as you can to get better performance, you can always start them up again later.
If none of this works, you may need to upgrade your graphics card...sorry.

PowerMac G5 doesn't eject

Your DVD wont show on the desktop unless a DVD is inserted. Which means that the DVD is either upside down, or simply isn't recognized by the reader. There should be an eject button on your keyboard. Hold that for 3 to 5 seconds and see if it ejects. If not, look for a tiny hole in the front of your case and insert a paper clip and push in until the DVD ejects. Some Macs have no hole and require a shop to extract the DVD for you. Another trick is to start up the PC while holding down the C key during bootup, which will make the PC try to boot off of the DVD. At which point the DVD should eject as the system asks for a proper boot cd.
