Power Mac G5 Dual Core Screen Goes Black Randomly But Seems To Still Be Running. I have to Force Quit

I totally just typed way to much info in the title.
In any event, my G5 Dual Core's(late 2005) screen will randomly go black with out notice. Its happend while designing in illistrator and also while browsing google(primarly the use of my comp is graphic design). The fans stay on and it sounds to still be fully running however the screen will not wake up and if i tap the power button it doesnt wake up either. I reset the "PRAM" while booting up, i toggled my screen saver/power saver also so its "never".
I thought the HD was faulty cause it sounds like a light saber at times... I figured the OS was crashing(im ingorant) so I bought a new one and more ram as well. I've installed the HD and am waiting for 10.3 OS to get here in hopes that the new HD and OS will not crash(again that was my educated guess as to what the issue was).
Is it a video card issue? faulty cable you think(VGA to DVI 17" Samsung)?
Thanks so much in advance for any and all feed back along with the patience of a newbie to the forum/community world.

Hello,
Have you blown the dust out of it lately, especially the Video card, Power Supply, & RAM areas?

An advice for an used Power Mac G5 dual core 2.3

Hello.
I used a Power Mac G5 PCI-X (sett. 2003) 2.0 GHz, working with Photoshop. It worked great for yeras, but now, due to its typical logic board lack, it got broken and is unable to boot anymore (three times flashing power light).
Now, I use software for PowerPC CPUs, so I can't get new computers, because I should replace all the software too!
I'm going to buy an used Power Mac G5 dual core 2.3 GHz:
http://www.everymac.com/systems/apple/powermacg5/stats/powermac_g5_dual2.3.html
This is the configuration:
Ram: 5.5 GB
HD: 250 GB
SVGA: GeForce 6600 - 256 MB.
About 650 dollars.
According to you, is this a good product? do you know any issue or manufacturing fault?
Would you buy it if you were me?
Thank you!

I tried heating it (not with the hair dryer), after about 1 hour it booted and worked very well, as in past. But when I powered it off, it started again with the same problem: unable to boot and three times flashing light.
I need a working system.
Furthermore, I removed the hard disk (sata 160 GB), and installed it in a Mac Pro: but it recognized only the second partition (data). So I run the Disk Utility and gave immediately an error (wrote in red and big), writing that the hard disk had a serious physical problem, and that if the computer was able to see the disk, I had to make immediately a backup.
But the three-times flashing light error of the G5 was not given due to the hard disk, because I tried several times to boot it from the OSX DVD, also removing the hard disk, and it always gave the same problem.

Power Mac G5 Dual Core freezing

Hi,
Everything works fine with my G5 with 4GB RAM, except one thing:
Sometimes when I work for a long time, my mouse justs freeze,
The red light near the RAM slots appears and the fans start being noisy ! (LED 7—Checkstop: red—contact Apple or an Apple Authorized Service Provider)
I reboot and all just works fine until the next freeze
I ran Hardware test and apple diagnotics many times but all the tests including the ram test passed successfully.
It happens like 1 or 2 time by day. I couldn't identify the cause or the frequency of the problem (maybe Eyetv usb box, or a spécific app that causes the computer freezing ??? !)
Thanks for the help !
Power Mac G5 Dual Core 2,3 Ghz Mac OS X (10.4.8)

Curiously - we have two new Dual 2.3 G5s and they exhibit this same behavior. Suddenly freezing - and not necessarily while we have a lot of apps running. iTunes is always going in the background though. I'll start monitoring the temps on these machines and we'll see what happens. Does anyone know of a menubar app that might display CPU temp on the fly? Could be useful if we see a spike in temperature and then a crash.
One notable thing though, when it does crash, it crashes hard. Everything freezes, the audio (since iTunes is usually running) begins to skip on the last section of the track it was playing, sort of like a skipping record - only much faster. It also appears to have happened to one of the machines last night while it was asleep. I came in the morning the the fans were going crazy - and yes, the little red LED was on. What does that mean?

Screen goes black randomly

Hi everyone.
I have a very strange issue on 2 different PCs.
From time to time the screen goes completly black, and I have to wait about 2-3 seconds for it to restore the picture.
Both have NVIDIA video card, one PC has GF8900GT the second GF7200.
Both PCs running GNOME
In both PCs the screen is connected via DVI port.
One PC has Arch installed for about 4 months the second has a 3 days old installation.
I also have a laptop with Arch (about 4 months) but I didn't expirience any issues there.
I'm not sure what the problem is, but it really annoys me.
I'll be very gratefull if someone points me in the right direction.
Thanks in advance.

Hello dhruid,
Thanks for the question. After reviewing your post, it sounds like the screen goes black randomly. I would recommend that you read these articles, they may be helpful in troubleshooting your issue.

my iMac won't boot up. I hear the chime and the Apple symbol appears but there is no whirling indicator that appears and after a while the computer screen goes black and the whole cycle starts again.

Since you have Lion v10.7.4 installed, use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

Mac keeps FREEZING and screen goes BLACK!?!

My computer freezes up and eventually the screen goes black withe the rainbow waiting mouse. So I restart it manually by pressing the button, and turn it back on again. I login, the old programs come back on. I try to click something. The screen freezes andgoes black again with the rainbow waiting mouse.
This happens everytime.
Repeat. Repeat. Repeat.
-I left it off all night and tried it again in the morning. Didn't work.
-I think it started when I plugged my iPhone 4 in the usb.
-itunes wants to update but I can't do it.
-between restarts, I noticed that there was a software update sign, but my computer kept freezing and turning off.

Macbook 2009 screen going black randomly

My macbook 5,2 circa about autumn 2009 (white plastic) keeps randomly going to black screen whether or not the power cable is plugged in. I've reset the SMC but no improvement. It sounds like the fan is running all the time too - and when the screen goes black, it sounds like the whole thing has shut down. After a short while it appears to wake up again.

This could be a sign of a failing drive. Considering the age of the machine, it's not unexpected. I recommend that you backup your data as a clone to an external drive in case of failure.
Both of these applications can be used to create a clone.

I upgraded to Mavericks and my iMac monitor goes black randomly, but my attached cinema monitor stays active. I can fix it by putting it to sleep and waking it up again. But often it happens immediately after.

I have a 30in cinema display attached to my iMac and the iMac screen randomly goes black while the cinema stays active. I can put it to sleep and log back in which fixes it, but often it happens again immediately after. Sometimes it happens so quickly I can't even finishing logging in! I'd like to know if this is a Mavericks issue and I will roll my machine back. Thank you!

Wanted to update you on my situation with this.
So far 8 hours have gone by and I have not had a screen blackout.
FIRST I did the Hardware Test. TWICE on the extended test, the instructions on the KB Article explain. It took almost 3 hours, but while the test was running, both times, my computer screen did not go black.
I did get an error message, both times. Different each time. I looked up both of the error messages on discussion boards. Lots of conflicting info
One good thread said my first error was that my hard drive was bad and would probably fail.
The next error message I researched said that a fan was bad or needed replacement.
(information comes from other folks on discussion boards, not from Apple or technician)
Not sure what exactly those 2 error messages indicate but I followed a thread where someone found a solution by doing the following. So far it's worked.
After Hardware Test I did a shutdown and an SMC resest. Unplugged computer power source from wall and computer for about 10 minutes.
Finally after a restart I downloaded "SMC Fan Control" (CNET Downloads has a nice safe copy you can download)
There is a temperature monitor and from what I've read so far, keeping the CPU temperature under 50˚C is ideal. Making sure your fans and computer is in a well ventilated area/room too of course.
The SMC Fan Control helps you set your own speeds on the fans and so far everything has been going normal.

I have Sun Life Financial bookmarked and when I click onto it, as it is trying to get on the site, the https tool bar goes wonky. Then the pinwheel comes on and I have to force quit. This does not happen on our other apple computer only on my new one

I have not used this app before so please excuse me if I am duplicating my question. I am trying to get onto one of my books marks but when I click on it, it starts going all wonky in the https bar. Then the pinwheel comes on. When I force quit and then go back into Safari it comes up on that company website but a different section that is asking me to check the date on my computer and some other things that could be a problem. This does not happen on our other mac only my new lap top. This problems only started this weekend. Any ideas?

Thanks for the response.
I attempted to remove cookies, but I can not identify any of the cookies on the list with the PrimeVest web site. No PrimeVest, no PVs, nothing that looks like it came from them.
I have also reported the problem to PrimeVest and their tech did answer. He suggested erasing the browsing history (temporary internet files), which I did with no effect. He also had me check for the correct starting page address, which was OK. He stated that they are aware of a problem and it is on their list. No indication of how far down that list though. His only cure was to use IE for now, which I was already doing. Perhaps he can tell me which cookies to remove.

I have a MacBook Pro with Retina display, when starting up, I see the Apple logo, the bar underneath fills about 1/4 of the way, and then the screen goes black, the mouse cursor is still visible.

Boots to black in OS X mode (I believe 10.10.2? tough to check right now). I can boot into Windows 8 using Boot Camp without incident. I have booted to Disk Utility and run Disk and Permissions Repair. I have booted into Diagnostics, and no issues were found (ADP000 was the Reference Code given). I reset the PRAM, which gave a louder chime than I had been getting when failing to start up OS X, but otherwise no change. Feeling that my options were exhausted, I attempted to restore from Time Capsule, and it won't connect to Time Capsule, despite Time Capsule being the active router whose network I am connected to. Please advise.
(This is my girlfriend's computer, she tells me that she selected an option to perform an automatic update later, that night.)

Install or Reinstall OS X from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
      left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
      the Security button and set the Zero Data option to one-pass. Click on
      the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
           because it is three times faster than wireless.
This should install the version of OS X that you had installed.
Be sure you only work on the OS X volume, not your Windows volume. I cannot tell you if you will still be able to boot the Windows volume after the above. You will need to find a fix for that.

Mac screen goes black every 2-3 minutes, returns after 1 second, Mavericks

My MAC, updated to Mavericks, screen goes black every 2-3 minutes, for one second, then returns. Has anyone experienced this? How should I correct it?

SOLVED!!!!!
SO I did some more digging around and read ATI cards seem to overheat easily. I knew the fan was working, but after closer inspection I realised there was ALOT of built up dust on the card and clogging the fan and airflow. Blew it out with alot of compressed air, stuck it back in the Mac and BAM...no black screens. I tested it by streaming 6 video sources...doing 2 screen captures at once as well as watching a HD movie in fullscreen. Did all this for 30 minutes and no crashes. I also downloaded an app to monitor the temps inside the computer and the expansion bay stays at 41 degrees. No clue what it was before but obviously it was hotter than that. So my problem is solved! Funny that 10.7.5 made the card work harder. I wonder if its off loading some CPU stuff to the GPU for processing more than 10.7.4 so its just working a bit harder and so it heats up faster....

Screen goes Black - Mini Display Port!

Hi!
I've just started using 'Dr. Bott Mini DisplayPort to HDMI Adapter Pro with Optical Audio' today on my 13" MacBook Pro, and it was working fine, that is until now! Every time I take the Mini Display Port out, my screen goes black! The computer is still on and running, and I can adjust the brightness, but I can't see anything! I have to put the Mini-Display Port back in for the screen to come back. Have tried restarting, and the white screen with Apple logo comes up, then just blackness!!! Until of course I put the Mini Display Port back in!!!
Please help! Am freaking out that I've had two faulty MacBooks in a row!!!

Dual monitor for Power mac g5 dual 2.3ghz

I wanted some advice on which monitors to get for a dual monitor setup and if its even possible to setup on my G5 or do I need a different video card?
Here's my computer spechs:
Power mac G5 dual core 2.3 ghz (late 2005)
Model: A1177
Memory: 2GB DDR2 SDRAM
HDD: 250GB
OS X 10.5.8 Leopard
The only thing I run on this is logic studio 8. I wanted to expand my setup but not sure how.
Any advice is greatly appreciated! Thanks
< Edited by Host >

It depends on which video card you have installed, though not much. Whichever card you have installed, you should have two DVI outputs available. With the minimum 256 Meg VRAM, you should be able to support two 1920x1080 monitors without a problem, and the "HD" monitors are getting very plentiful and dropping in price. Were I to buy today, I would make sure to get an LED monitor, as that flavor should have a longer overall life than a florescent panel monitor. You can find monitors in 23" dimensions for under $200 a pop, and more 27" monitors are showing up at a slightly bigger bite.
