Reinstalling MacOS does NOT fix the problem for me. I'm still searching a solution !

When turning on my imac, it loads to a blue screen with a turning wheel and never gets passed that. I have tried booting to safe mode and it still doens't work.

When turning on my imac, it loads to a blue screen with a spinning wheel. It never gets passed that screen. I have tried power up to safe mode and it still doesn't work. I have music files saved on the computer and I don't want to lose any of my files. Can someone help me?

Zap the PRAM and Reset the SMC, and see if that fixes it. BTW. detailed computer and OS info goes a long way to solving problems.

I have an iMac G5 stuck on the gray screen with spinning gear. I woke up to it being stuck on a blue screen, then force quit and now it's stuck on gray with spinning gear.

I have an iMac G5 stuck on the gray screen with spinning gear. I woke up to it being stuck on a blue screen, then force quit and now it's stuck on gray with spinning gear. Please advise.

If you have a G5 then it's a PPC (Power PC) based iMac, this is an Intel iMac forum. Try the Gray screen appears during startup link for troubleshooting steps. I suspect the HD has crashed.

Rental movie on i pad stops playing, then screen goes dark. any solution?

rental movie on i pad stops playing, then screen goes dark. any solution?

Quit the video app and restart. Go to the home screen first by tapping the home button. Quit the app by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on the video app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the video app icon to close it. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button. Try the app again and see if the movie is there and will play.
If that didn't work - Search for the movie. From the home screen swipe to the right and the Spotlight Search feature will appear. Type the name of the movie in the field at the top, if the movie shows up in the search, tap on the icon and hopefully it will begin to play. Let it play for a few minutes then tap Done. Return to the video app and see if it is in there now.
If that doesn't help - reset the iPad - hold down on the sleep andhomee buttons at the same time for about 10 seconds until the Apple logo appears - ignore the red slider - let go of the buttons. Let the iPad restart and try the video again.

Flashing Screen - with new installation

I recently bought a new 60gb video ipod. My roommate had been using my computer, Windows XP, for his ipod, but is no longer needs to use my computer. I uninstalled his itunes and quicktime software from my computer so I could start clean with my new ipod. I install the software that came with my new ipod with a complete installation I plugged in my ipod. Itunes appears to detect my ipod but I have been watching Do not disconnect flash on my ipod screen for an hour. I have tried resetting both my ipod and computer multiple times, and have reinstalled the itunes software a few times as well. I tried updating the itunes software, but all my effort still leads me to the same flashing screen once itunes in operating. I can successfully eject my software using the itunes shortcut, but once the ipod is plugged back in I get the same flashing screen. Any help would be greatly appreciated. Thanks.

I have the same problem: flashing screen, however with one variation, Itunes does not detect the iPod. So I cannot change from manual to automatic because the Itunes says "no iPod detected". I have tried reinstalling the software, resetting the iPod, and the iPod updater will not see the iPod as well, so I cannot update the software on the iPod. This seems to be an extremely arcane system! Can anyone help me please? Windows seems to grab hold of the USB connection and mount it immediately as a hard drive interdicting the iPod software. Windows explorer sees the Ipod hard drive and I can even transfer files to it, but the ipod software does not see the files! So I'm in the woods on this one. Can anyone help me on this, please?

Flash Screen with JWindow

Hi All,
I want to make a Flash Screen when my program start, and shows some information before hiding it and display the main window. I read from the forum that I should use JWindow to achieve what I want.
However, Forte doesn't have a JWindow template, I search for the site and cannot find much about how to use JWindow. Can anyone here kindly help me?
I want some sample code, or some resource about how to use JWindow.
Thanks

better try the following code

Imac G5 stuck on white loading screen with gray apple and spinning wheel

I purchased this imac from a rebutable seller on ebay. He obviously had it working before he sent it to me, and he has been helpfull the whole way through, so I am positive this computer is not junk. When I recieved it, I plugged it in and turned it on, at first nothing would show up on the screen and the fans came on. Then, I contacted the seller and he told me to hold the shift key while turning it on. That did work to some extent. Now when I turn it on, it is stuck on the white screen with the gray apple and the spinning wheel. He had just updated and installed EVERYTHING imaginable so I am positive everything is up to date. I am not sure what to do, I have researched this but I cannot seem to find an answer. Oh, and even know on the white screen the fans turn on. It is quite weird.
Well, I hope someone can help. Thank you.

Call AppleCare. You should not be having problems with a brand-new machine.

TS3824 imac g4 (2002) stuck on grey screen with apple and loading sign

my apple imac g4 2002 wont load up it stays on the gray screen with apple on the front with loading sign underneath. ive tried almost every way ive seen online to try to factory reset it but nothing works. i got it as a gift a few years back and really need it now. can someone help? please, thanks.

churpchurp22,
You are posting on the wrong forum, this forum is for Intel based iMacs. A 2002 G4 would be a PowerPC machine, please post on the correct forum. My guess though is the HD has packed up and crashed.

IMac 21.5" boots to white screen with vertical blue lines/bars then locks up

iMac 21.5" (mid 2010) Intel Core i3 4GB RAM with Radeon HD 4670 boots to white screen with vertical blue lines/bars:
Then it locks up after a few minutes, at which point the screen changes to white with these blue symbol things all over the screen:
If boot to Safe Mode, it still has the white screen with blue lines/bars, but eventually loads the login screen and I can successfully login and get to the desktop, but even that has the bars/lines.
Eventually, after enough restarts or hard shutdowns it will boot normally with no video/display issues. I've run disk checks, did the SMC and PRAM resets, checked logs (that I know of), and have even taken it completely apart, cleaned it out, reseated everything, put it all back together, but no change. I've read a few other posts about similar issues (but not quite the same video issue as this) where people had the logic boars replaced or reinstalled OSX, but that didn't always fix it. Any ideas? Has anyone seen this issue before? Thank you.

Is this a dead disk?
Very well could be.
If you can not startup from the Hardware Test, in Safe Mode or from > OS X Recovery as discribed in the Support article's.
Dig out the original Install Disc set that came with the iMac and do one of the following.
1. Attempt to Repair the Hard Drive.
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
2. Run the Hardware Test from the second Install Disc.
1. Insert Disc 2 and Startup holding the D key.
2. Select the Extended Hardware Test.
Then if you still can not get anything going, you need to contact your Local Apple Store or AASP and make a Service appointment.

If a reset doesn't work, try and force iPad into Recovery Mode:
1. Turn off iPad. Press and hold the Sleep/Wake button for a few seconds until the red slider appears, slide to turn off.
2. Connect USB cable to computer
3. Press and hold the Home button down and connect the docking end of cable to iPad
4. Continue holding the Home button until you see the "Connect To iTune" screen
5. Release the Home button
6. Open iTune (make sure you have the newest version of iTune)
7. You should see "iTunes has detected an iPad in recovery mode"
8. Use iTune to restore iPad
Note: You need to be patient and repeat the above many times to recover your iPad
