IMac G5 Screen and Startup Problems!

I purchased my iMac G5 in August 2005. I have had it for 4 years now and have never had problems with it. Last week, while the screen saver came on, the computer suddenly froze. I shut it down manually by holding the back button and turned it back on. The fans run loud and fast and the screen remains blue. It doesn't load to the home screen. I have restarted it, shut it down numerous times and nothing happens. The screen display glitches and makes weird, distorted color patterns. It doesn't respond at all. It does this each time. My computer seems like it broke! I have a lot of pictures, music, and important files on this computer and cannot access them at all! My warranty has expired also. Need help!!!!

Mine is doing almost exactly the same thing, and it also froze the first time while the screen saver was on. I suspected a software issue, and have gone so far as to wipe the hard drive (erase, plus zero all blocks w/disk utility), and reinstall the OS fresh and it still does it. The hang occurs just as I get to the blue startup screen, but before the "Loading Mac OS X" box & progress bar shows up. I also get the display glitches from time to time, but not all the time.
The one small bit of relief is that I am able to consistently get the machine to boot completely in safe mode, but not "normally." Any advice on what may be going on here?
To College Kid: try starting up your iMac in safe mode - hold down shift until the "gear" starts rotating under the Apple logo on the startup screen. That was how I was able to get mine started up to get the data off before I wiped the drive.

Please Help: iMac black screens after startup logo + spinning wheel no cursor).

Hi, guys.
I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
I've tried rebooting over & over again; the results are the same.
The steps that led to the problem occurred thusly:
1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
2 - One particular process I quit was 'launchd' which was functioning under my profile username.
3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
Thank you I'm advance to anyone with advice on how I can go about fixing this.

Gray screen appears during startup

IMac 20" sound and other problems

My dad has just bought me a 20" intel iMac for my 18th birthday, and has let me have it 2 weeks early, and I love it!
But yesterday i ran into various troubles. I turned my mac on, hearing the usual startup chime,but there was no sound at all coming from the internal speakers as soon as I got into Mac OS (fully updated as well as firmware 1.01) e.g. playing a song on itunes. Absolutely nothing.
When I plugged in my usual external speakers into the headphone jack, the sound was unusually low, and when turning the external speakers up there was a very distinct crackling sound along with the music that was playing.
This, I thought, was just a minor problem that could be easily rectified. That was until my screen went a dark transparent grey with a multilingual message telling me that I needed to restart my computer. So I did, and mac os booted up again telling me that Mac Os had encountered an error. I sent a report to apple at this point too. Then the screen went transparent grey again telling me to restart.
This continued, and I decided to quickly back up my files to a nearby pc (I'm recently converted to Macs), and I inserted my Mac Os install disk. I knew what I was doing as I'd formatted a few days ago due to accidently erasing my mac partition whilst trying out bootcamp . I did a full erase of the mac harddrive, and started the install process, when the grey screen happened again! This led me to beleive it wasnt a software fault. I restarted and attempted to install again. This time no grey screen, but a horrible noise came from the under the bottom left of the screen like a violent clicking. I turned the mac off straight away. I booted up again and installed Mac OS without any errors.
Still, no sound and still the grey screen popped up. I finally decided to phone Apple up with the number from the applecare box. The man on the other end guided me through various diagnostic procedures, getting me to hold applealt+RP, and got me to reinstall mac os, at which point we hung up.
Mac OS worked fine this time with no grey screens, but the sound still didnt work. I phoned applecare up again and a woman showed me the sound pane in system properties. The Output listing didnt show internal speakers at all and just showed Line Out. Well all in all my mac is in the same state right now, apart from I keep getting more and more grey screens, and it seems to be really unstable when trying to install software updates for example.
The woman on the phone arranged to have it repaired, but I was wondering whether anyone had any clue as to whats going on with my mac.
I'd really appreciate any ideas or comments about it. I'm sorry about the length of this post too!
iMac Intel 20" Mac OS X (10.4.6) 2x 512mb ram

hey rob,
if your machine was okay, up to the point of your 'experiment' with installing windows, it looks like your problems stem from a dodgy reinstall after the bootcamp attempt [i did the same thing, duing the formatting prep for windows, erased the os x partition bahhh]...i reinstalled and i haven't had any problems since[trying to find a slipstreaming scheme with the older xp pro disk i have].
importantly, though is this clicking sound, not good.
i'd like to know, through looking in the apple system profiler what brand HDD your machine came with. there would be letters designating western digital, seagate or maxtor.
it may be, that this component is faulty. imho i'd prefer one brand over another that apple uses, other threads on the subject have different opinions about that...; ^]

Blue Screen and Sound Problems, In Desperate Need of Assistance

About a week and a half ago, my computer officially stopped showing anything on the display when I tried to start it up. It had been doing it on and off for a long time, but I would eventually get it to display. Not this time...
My husband and I took our 30" Cinema Display and G5 tower to the iStore. The display was tested, and it worked fine. The associate said the problem was the video card.
After doing much research, I decided upon the flashed GeForce 7800 GS, per the suggestions of japamac on this forum. After I received and installed it, the display worked again and everything seemed great! It came with a CD with a patch on it, saying it was for *10.4.9 or later*, so I installed the patch and ran the permissions command. I had to go on a business trip immediately as the permissions command was running, so I left the computer to do it's thing, knowing it would sleep after a while.
When I got back home from my trip, I eagerly hopped on my computer. I attempted to awake it from sleep, however it froze. I was not able to tell if the permissions command ever finished completely.
I restarted the computer and everything seemed fine. A few hours later, my husband hopped on the computer about to test the new card on a game, but it froze before he could do anything. We restarted the computer, and that's when the blue screen issue started.
I tried resetting the PRAM, starting it up on the install disc (which didn't work), I tried holding down the S key (which also didn't work), and I tried holding down shift for Safe Boot.
The Safe Boot works, in fact I'm on my G5 right now. I did the permissions command again, thinking that it must've not ran all of the way and the permissions were broken. When it finished it gave me a massive list of "permissions differ"s with 10 "Warning: SUID file "____" has been modified and will not be repaired" messages at the end.
I contacted the seller on ebay, who ended up telling me the patch was only for Tiger, despite the file saying "or later". I really thought I messed up the permissions badly from that and tried running the permissions repair, but that did not help.
Thinking I had no other choice, I backed everything up and I reinstalled Leopard (choosing to Archive). After it finished reinstalling, the computer restarted and it booted up normally. I thought my problem was solved! However, once I let it sleep and came back later, it was frozen. I restarted and had the blue screen problem all over again, to my disappointment.
I tried restarting, the PRAM, the permissions (which did not list those SUID warnings anymore)... There was once that I restarted and it gave me the blue screen, I tabbed twice, hit enter, and entered my password though I couldn't see anything. I heard the computer moving like it was logging in. I pushed the power button on my display, and magically the screen displayed my desktop with the "Are you sure you want to put your computer to sleep?" window.
However, this only happened once, and afterward I noticed an issue when I tried to wake the computer from sleep. It would try to wake up, then go back to sleep, try to wake up, go back to sleep... So I contacted the ebay seller again, explaining what had happened and that it made me think it is an issue with the card itself, not permissions. (Fearing that if it is permissions, I would have to reinstall the OS again, but choose to erase the disk this time.) I asked if the seller knew anything about this.
The seller contacted me back saying, "Hello again, yes, wake from sleep is a common issue of many modified cards for Mac , so you better turn it off if you are not use it, its better for both the video card and power supply of your G5,
hope you understand about it , thanks". Well, that really would have been nice to know in advance... but regardless, the more important issue is the blue screen on startup.
On top of all of this, when I tried to watch a video tonight I noticed the sound was not working. I made sure it wasn't muted, I made sure the optical cable was connected, nothing. I restarted, nothing. I did not have any problems whatsoever with the sound before this, and I'm not sure if it has anything to do with the card (I wouldn't think so), or that something needs to be reinstalled since I reinstalled the OS. The System Prefs > Sound, Is not finding any devices.
I've restarted the computer so many times since the initial failing of the video card, I really hope all of the restarting hasn't damaged anything. As old as my Mac is, it's been working perfectly normally until the graphics card went out. After that, it's seemed like everything is falling apart. Thank you for reading my long history of difficulties, and I hope someone (maybe japamac?) can help me!

Hi-
I understand why you would suspect the latest hardware addition, and the conflicting/misunderstood advice given by the seller isn't helping.
I don't know of any cards that have "known" issues with sleep from the flashed realm.
Of the 10 different makes and models that I use or have used, flashed by myself or others, I have never seen an issue with sleep.
This includes 2 different Geforce 7800 GS cards.
The most common reason for a blue screen at boot is an incompatible Login or Startup item.
These are disabled during a Safe Mode boot.
http://www.thexlab.com/faqs/startupitems.html
As for the Geforce 7800 GS, there was a patch for OS 10.4.9 only. This was to allow for the proper reporting and use of the appropriate OpenGL engine.
After 10.4.11, and in Leopard, the OpenGL engine is properly selected for the card.
Since this is simply a reporting issue, and not a performance issue, the patch is not a mandatory thing.
There is an issue with the ROMs used in some Geforce cards that causes a boot delay (a blue screen) for up to 6 minutes.
Most guys don't use those ROMs anymore, but I guess that someone may not have bothered to get the new ROM.
Removing the AppleHWSensor.kext from /System/Library/Extensions will correct this issue.
This, however, is historically a G4 issue only.
There are a couple possible scenarios that I think may apply to you:
1- The card is overheating, thus the occasional success or Safe mode only boots.
Check that the fan is spinning.
2- The auxiliary power is not connected, or has a poor connection.
Sometimes the pins on a Molex adapter (the female side) are so tight that they push out, rather than allowing the male pin in.
Conversely, a stretched out female pin would not properly contact the male pins of the graphics card.
Double check connections at the optical drive and at the graphics card.
While inside, reseat the graphics card.
3- If the card was prepared for use in a G4 by cutting the traces of pins #3 and #11, this can cause problems in the G5.
Most cards work fine, but some Geforce cards complain.
As well, if the pins were taped, the tape should be removed for use in a G5.
http://themacelite.wikidot.com/pins-3-and-11
If the traces are cut, return the card.
If the pins are taped, remove the tape.

7.0.3 battery and startup problems on ipad

Since I did the 7.0.3 update, two problems have arisen on my ipad 4.
The first is that my battery drains fast when not in use. It used to be that if my ipad were left alone, unplugged and on but not in use, the battery barely drained. But now it drains like I've been watching movies on it all day. The first day after the update, it sat on the counter most of the day unused, and it shut down because the battery completely drained out. It's been like that since. I have to turn it off now, when not in use.
Also, when I turn my ipad on, it takes forever to start up. It just sits with the apple icon on the screen and it's like that for so long, I think it's locked up. Eventually, it comes up. This happens every time.
Since I never had these problems before, I'm assuming that it's a result of the update. Prior to the 7.0.3 update, I had done the previous version 7 updates and have been using it with no trouble. So this wasn't an update from version 6 to 7. Please let me know if you have any ideas, thanks.

Two things that might help. Reset all your settings and reset the phone. Use the Settings app to reset all settings. Settings > General > Reset > Reset All Settings Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that helps.
As far as the battery usage, check your settings. The iOS 7 update adds new features and turns them on. You may not need all of them to be on. There are many threads in this form with suggestions for reducing battery usage.

Intel imac G5, Safari and Godaddy problems

I have an intel imac G5 with OS 10.4.5 with Safari 2.0.3 and can not access my GoDaddy hosted website directly or with forwarding (on or off)...
I can however access the GoDaddy hosted website with my imac G5 (non-intel) with the same version Mac OS and Safari and with a Windows computer.
I can only assume this is a problem with my intel imac?
Another weird problem...my site is still on an SBC webhosting.com hosting server and I can only access the SBC hosted site with Safari not the Godaddy site. SBC has not cancelled the account and has not taken the old site down as of yet.
I have tried clearing the cache, Firefox, and pinging the godaddy site ip address.
Any advice would be appreciated. Thanks.

very strange...right after I posted, I received an intel mac security upgrade...installed it and the problem was fixed...wow...
sorry for the post...

Black screen and applications problem on iPhone 4S after upgrading to iOS6

I've upgraded my iphone 4s to the iOS6, all the applications suddenly stops while I am working on it, then the phone shows a black screen and after some seconds shows the main menu screen. When I open the application again after that, things I was doing were lost. Even if I am making a call, the black screen appears, the call is muted to me for a while until when the phone shows me the main screen again and I have to tap to the call. If I am playing music, suddenly the phone shows the black screen and stops the playback, after of it, I try to recover my playback but there is no playback. And happens with everything: facebook, mails, sms, maps, among others. When I was using the iOS 5.1.1. phone was working well.

i looked on the right there is no solution to my problem.i charge my phone to 100% after 2 hours with no usage at all of the phone with 3G off with wifi off with all applications shut down all notifications and locations off battery goes down to 50% when it was running on the older ios never had this problem in my iphone.when will this problem solved

IMac Glossy Screens and Calibration

I talked to an Apple store rep the other week and when I asked when Apple would ever get a matte screen for their iMacs, she replied why did I want one? I replied that I do photographic work and the glossy screens were difficult to work with. "What? I have a friend and they love the gloss screens" They saw no need for the matte screens. I have to occasionally use my wife's Dell laptop 17" with a gloss screen and it drives me nuts.
Found some support.
From Martin Evening's Photoshop CS5 book (pg 89) - "Meanwhile Apple's passion for glossy displays means that their newer displays are actually worse than the old ones. I have found it impossible to calibrate the new iMac displays and makes them unusable for Photoshop image editing. The only viable solution has been to run a secondary display off the iMac I take on location, which kind of defeats the reason for having an iMac in the first place!"
Has anybody heard of any hope of Apple bringing back the matte screen? (also the 24" iMac which was the perfect size.)

There are screen films that you can apply, but lots of folks here have reported mixed results.

IMac, gray screen and beeping.

5 or 6 year old iMac running leopard. Don't know version, but always updated. I downloaded skype last night. Everything working fine. This morning, while going through Skype info and buttons, got a mask saying "need to restart" or "need to refresh" (not sure which). I had no mouse or keyboard controls. Held power button down to shut off. Restarted, then gray screen and constant beeping. Tried several times, same result. Unplugged from power then restarted, same result. Help?
(working from my laptop)

Sounds like you got a kernel panic. A kernel panic is usually, but not always, caused by hardware, with memory a leading cause. Once you're able to reboot, if they continue, see this kernel panic FAQ: http://www.thexlab.com/faqs/kernelpanics.html
On the gray screen and beeping, if your iMac has an Intel processor, see this Apple note: http://support.apple.com/kb/HT2341?viewlocale=en_US . If it has a PowerPC processor, see: http://support.apple.com/kb/HT1547 . If you're not sure, Intel-based iMacs were introduced in early 2006.

Computer, black Screen and reboot problem

I have problems with my computer black screening and rebooting randomly recently. Tried a few things like downgrading the nvidia drivers and only using one monitorscreen.
I was using version 347.52 but downgraded to 344.11 but still got the problem
The times this happens can be anytime but happens most often while i'm playing games and at the moment i'm only playing on normal graphics while my graphics card should be well good enough to handle ultra graphics.
I used this program "WhoCrashed" and got this crash report:

Graphics problem at lock screen and startup

I am using a Macbook Pro 15" from mid 2012, with the most up to date version of Yosemite. I'm placing this question under the Yosemite category because the problem started directly after I updated. The weird screens appear at every startup/reboot ("[Update Needed]", pictured) and lock screen (sort of pixelated mashup of the various items on my desktop, not pictured). Everything is up to date, and I've tried safe booting.

My Mac won't boot past white screen and startup keys won't work

Hello. I have an iMac not sure what year.
So about a year ago it froze and wouldn't restart, so I neglected it for a year. Now that this my only fixable Mac I have been researching to fix it. I was able to boot into safe mode about a week ago for a little bit but then it froze again. Ever since then none of the startup keys work, even resetting the PRAM, I heard the second ding and then it just brings up the cursor on the white screen with no disk options.
I have an external disk drive connected to the USB I'd like to boot my Mountain Lion from but since the start up keys don't work I don't know how to do that.
Any help would be incredible, I do not care about saving anything from the computer I just want it to work. I hate dealing with the "geniuses" so that's not an option.
Thanks

When you hear the startup tone hold down the Option key and you should be able to boot into the Recovery Partition if you have Lion, Mt. Lion or Mavericks on the internal HD. If even the Option key does not work then your keyboard may have dead batteries or be defective and in need of replacement.
If you have ML on the EHD as a bootable clone then you should be able to boot from it.
My best guess is you have a failed HD though, my advice is to take it in for professional diagnosis to your local Apple Store or AASP and get a quote on what is wrong then decide how you want to proceed.

IMac Blank Screen on Startup, No Chime

Hi,
I have a 2.0 Ghz Intel iMac (20") that had a crash during a game of Age of Empires (just about to win as well.... ). I tried to turn it back on again after a force shutdown and the hard drive whirred but there was no chime and the screen remained as black as it is when its off. The white power light on the front stays on solidly but after leaving it a few minutes, nothing happens! (Ive tried taking out all USB/Firewire devices except from the mouse and keyboard too)
Any suggestions before I take it to the nearest Genius Bar would be greatly appreciated.
--Lee

I'm used to opening up macs and changing bits and bobs and always take the necessary steps to avoid damaging components through static or other means regardless of if manuals have the warnings or not.
Edit: I haven't opened up my iMac though (nor will I). I can guarantee I was not the cause of the problem I was referring to the old G3's and such I have lying about the house.

Black boot screen and startup manager on mid 2014 rMBP after upgrading to Yosemite

After upgrading to Yosemite I'm experiencing black booting process. Moreover, I noticed that the startup manager, which we access by holding the option key, has the black background too. I didn't like the Yosemite, so I downgraded back to Mavericks, but I still have the startup manager with the black background and the initial screen during the startup sound is black too, and after that the grey screen with the Apple logo comes up, which is typical for Mavericks. I want my startup manager to have the grey background as before. And also, before there was the grey screen during the startup sound, not the black one. How to revert all this to the previous state? I'm experiencing all this on my rMBP, 13-inch, mid-2014.
I want to revert because after downgrading back to Mavericks my rMBP started freezing terribly, especially on youtube, ebay and app store. And it's not just the web browsing, it's freezing when navigating in finder too. I know there are many experienced users here, so I hope that somebody can help me with this. Before upgrading to Yosemite my machine was running flawlessly.

IMac - Slow load and wifi problems

I have lion installed on my macbook pro and on my iMac. My macbook pro works GREAT...no problems. My iMac - I am ready to toss out a window. Here are the problems:
INCREDIBLY slow boot up time - 5-10 minutes from off - 5-8 minutes from sleep
The hard drive is constantly working. I can have nothing open and it sounds like the hard drive is constantly spinning
Half the time my wifi hardware is not found on boot up and I have to reboot with slow load times - sometimes taking 20 minutes before I can get logged in to a 'working' computer
A lot of my programs have become slow. Safari can be slow responsive but others that are not apple that have done 'lion updates'
I have my activity monitor running and nothing seems to be hogging resources. My iMac specs are:
2.8 intel core i5
12 gb ram
2 TB hard drive with about 1tb free
I ran the lion update that came out and it did not seem to do much for me.
Anyone have a solution? Anyone tried a clean format and did this work? Lion works great on my laptop and I just need it to work on my main computer as well.
Reba

i think part of the boot up time issue is the amount of windows you happen to have open when you put it to sleep
other is lion upgrade slows it down due to this auto save function
my wifi is also spotty and acts like it can't find itself at times
and this is a brand new imac
