Intel iMac G5, black screen during erase and install -- PLEASE HELP!

My sister's Intel iMac G5 seriously has been a lemon, it has had SO many issues. It's now 2 years old, and has been rather slow for the maybe the last year, but over the last month or so it has gone way downhill, and it literally takes an hour to boot up, and 4-5 minutes to do anything (open an application, look at a photo in iPhoto, etc.). So, we've been trying to "erase and install" with her install discs to hopefully give the computer a clean boot and see if it helps at all. She has already backed everything up.
She started the erase and install last night, and it was going ridiculously slow. This morning when she woke up, the blue progress bar had gone about half way across. Then she went to get her kids ready, and when she came back in it looked like the computer was rebooting itself (gray screen with apple), but then the screen turned black and she can't do anything on it. Has anyone seen anything similar to this before?
We have had so much trouble getting this to work (we tried an archive and install a few days ago, but it gave her an error at the end). For about a day we couldn't even get the computer to boot up at all, but then miraculously yesterday morning it booted! Please help, I've converted her to Macs but if I can't get hers fixed she may never get one again!!

Does she have the Apple Hardware Test CD/DVD?

I'm afraid that it's a contradiction in terms to talk about an intel iMac G5. What your sister has is an intel machine, and she will find good advice by posting to the [intel iMac Forum|http://discussions.apple.com/forum.jspa?forumID=1110].

Black Screen During Gameplay and not High Demand Renders?

Hi,
The computer I own has been having issues with games that it previously had no problem with. 20-30 minutes within a session the screen will go black and audio will continue momentarily. The only way out of this issue is to hold down the power button for a reset. I have updated my drivers and cleaned out any dust with pressurized air. But the problem still continues. The strange thing is that I use Photoshop and After Effects for my work and there is no issue. Need help!

Hello masinic2,
I understand that just recently you started getting freezing and a black screen during game play and are looking to resolve it. I am providing you with an HP Support document: Using Microsoft System Restore (Windows 7), which will walk you through restoring your computer back to a point in time where you did not have this issue. This will not affect your personal files, but it will affect any applications you have installed or settings you have changed between now and the time you restore back to. You will have to reinstall or redo the changes that are undone during that time frame.
Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!

Black screen during windows 7 install on 27inch iMac

My iMac turns to a black screen during windows 7 boot camp install. I can use the install disk on my wifes Macbook Pro so I know that the media is good.

Please re-post in the Boot Camp forum.

Black screen during windows 7 install on mac mini

I have a mac mini 2013. Trying to install windows 7 via usb iso file. downloaded iso file to mac mini desktop from windows supported site. This is a 30 trial that can be installed after 30 with a genuine key, which I plan on buying. 8 gb usb stick. dloaded latest updates for OS and bootcamp. Ran bootcamp. pointed to iso file. partitioned 200GB fro windows 7 home version. clicked advanced and formatted disk for bootcamp..( load driver was also available, what is that??)
checked ALL 3 options BTW. It expands and loads files every time and gets to install select lang...etc. then computer restarts and hangs at black screen. caps and num lock light up when pressed, no other response. I can boot to safe mode in Windows but it say it has to return to normal mode to finish install, which then returns me to black screen. I can reboot to white apple screen with disk options and choose usb drive and it says loading files, then goes back to starting windows, windows logo appears, then black screen and just sits there have waited 30 minutes and nothing. I have read this could be a graphics driver issue? If so is there a way to force the support drivers to load, and how? this is for my Son and we have tried for a couple months with no luck, does the trial version have anything to do with it? I would pay for a windows 7 iso file download but no luck.

Hi wb2009,
I haven't found that the TV would be an issue, but did find an article that states to not have extra USB devices connected.
Boot Camp: Windows installation boots to black screen with blinking cursor
http://support.apple.com/kb/TS4536
The Windows installation may boot to a black screen with a blinking cursor. This can occur if you use a USB optical drive or USB Flash drive for the Windows installation and another USB device is also connected to the computer.
There's another article that mentions Windows XP or Vista that may apply.

Imac Grey screen require erase and install

I have erased and rinstalled about 6 times now. Works fine then eventually falls apart (freezes, safarie quits, then dies) and will not start as ball spinning with grey bar filling then shutdown wh about 1/3 through. Apple store did 2 of the reinstalls and sold me a back up disk. This is great as now I can rease and reinstall weekly without much loss. Also replaced hard drive under apple recall. But now same problems. Cannot repair disk as it goes so far and tells me to erase and reinstall. Not sure but getting close to tossing the machine. Already spent $600 on repairs with no progress. Apple store said har drive was fine and we were installing bad software, but we dot havemuch more the basics plus MS office
Anyone else out there have this issue

That ***** you can Easley buy a new hd for about 60$ 1tb for the iMac on eBay or any tech site and replace it. I don't think apple will do it again u can always try again

Ipod camera black screen when opened and sync prob HELP!!!

hello i just went to open the camera on my ipod touch 4g and it just went black just a black screen when i press the home button it goes straight to the home screen everything else is fine i just open the camera and a black screen appears, it is working fine now but just wondering if it is faulty or somthing.
some times it does not sync i will plug it into the computes usb port and it wont charge i takes about 3 to 6 tries to get it to work any help thanks

Same thing just happened to me, found another solution though.
Plug the USB cable into your PC/base of iPod Touch.
Turn off the iPod completely.
Wait 10 seconds and re-power the iPod.
Now load up the camera; and the screen should be back to normal.
I have similar screen freeze issue with my Sony Erricson K700i Mobile phone, and plugging in the 'power' cable always resolves it, so it would seem to be of the same method used to resolve this iPod issue!!
Strange thing as you've posted, all other apps etc still work. Maybe support will get around to resolving this bug!!

My camera is not working, just a black screen, won't take pics please help

WWhy won't my camera take pics..just a black screen ?

CClose the camera app and reset the iPad.
In order to close apps, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Next, reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

HT201412 my iphone is not turning on its freeze on the black screen with the apple logo.Please help me guys iam fed up please its a humble request

my iphone is not turning on its freeze on the black screen with the apple

- Try a reset.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Then connect to your computer and try to restore.
- See if placing the iPod in recovery mode will allow a restore. For recovery mode see:
iPhone and iPod touch: Unable to update or restore
- If the logo still show all the time, let the battery fully drain. After charging for an hour try the above again.

Black screen but this is different please help!

Hello!
Yesterday when I booted my iBook the screen was black (not just no backlight - totally black). Then I connected it to an external monitor and BOTH worked, my iBook screen was back and the monitor was OK.
BUT afterwards I wanted to start it again without the external monitor and now the screen is always black again.
I had the inverter and the reed cable (?) both repaired last year. They should not be the problem.
If I understand it right it is not the logic board because the video worked with an external monitor.
(I had the logic board repaired years ago and I am out of warranty now.)
PR-ram, PMU etc. resetting didn't help.
Does anyone have any advice?

Usually when the graphics chip is loose, the video on an external monitor is just as bad as the iBook's own display. It's possible for the iBook to work intermittently, however, so that may have happened with yours.

WINDOWS BLACK SCREEN AFTER VM WARE DEMO PLEASE HELP

I tried installing VM Ware Fusion Demo. I could not use my wireless mouse and keyboard, now I can't even startup with Windows. I get a black screen. Please help!

Go into safemode and uninstall the Nvidia driver you have installed and after restarting the computer and allowing extra time for windows to install a default driver for the graphics, install the Windows 7 driver for your computer found in the Toshiba download page for your laptop.
If you have issues with the screen blacking out after doing that, follow the instructions found here and this will correct that.

Black screen after 10.51 update, please help!

Installed Leopard on external F/W drive , although could not repair permissions on drive.I installed 10.51 then, display went black,and would not come on. Forced the machine to turn off. Disconnected external drive, pulled all the A/C cords,etc. Finally got it to start on the old Tiger OS on the internal drive.
Just got off the phone with Applecare and they gave me the old "We do not support 3rd party hardware". My external drive is a OWC 911 chipset drive with Tiger on the partition so I don't get it.
Is there perhaps something different about Leopard that precludes you from installing it on an external firewire drive?
Does Anyone have any ideas?

If cd boot was okay and attrib bcd was not, then the the bcd is apparently missing. Bad news. Time to restore the hard disk to its original out-of-the-box contents using Toshiba recovery media.
Are there important files to recover first?
Even recovery with "0" is impossible, though it did work fine previous to this.
If the recovery discs were not created, you can obtain them from Toshiba.

BLACK SCREEN WHEN MBP WAKES UP, PLEASE HELP!

This has occurred before and I read somewhere on the discussion boards that if you install the leopard dvd again, then click on terminal and type something in and quit installer the screen wakes up, but I forgot where I saw this thread, can anyone help me?
thank you

I can't help you with the thread but what I say might be similar to what you are thinking of.
Startup from the installation dvd by holding the C key at startup until the Apple logo appears. On the first screen select language. On the next screen choose Disk Utility from the Tools menu. Select your hard drive then Repair Disk. If repairs are needed and completed rerun the Repair disk to check that no more repairs are needed. If DU is unable to repair the disk you might need a service call although there are shareware programs that might be able to resolve the issue.
If no repairs were needed use DU again but this time choose Repair permissions and repeat this if there is a list of repairs done.
Restart normally after all this and see whether startup proceeds as it ought.
