Black rectangle on startup

I removed all the cables from the back of my Blue and White G4 (10.4.11) to do a spot of spring cleaning. On trying to restart I get a chime, the apple logo with spinning ball, then a black rectangle appears and the ball stops spinning
I have:-
1. zapped the PRAM
2. started from the install disc and repaired permissions using Disc Utility
3. started in Safe Mode and run TechTools Deluxe
Any help would be much appreciated.
Thanks
Tony

Hi-
I assume it may also be accompanied by a grayish screen.
This would be a kernel panic:
http://support.apple.com/kb/HT1392
Since you just did some plugging/unplugging, I would remove all cables again, open the tower and reseat the graphics card.
Reconnect monitor, keyboard and mouse only, and try starting again.
If still a no go, I would open it once again, and reseat the RAM.
While you're in there, make sure all other connections are tight.
Reconnect and try starting.
If that doesn't do it, you will have to look deeper:

10.4.9 Startup Prb. No blue progress bar: gray screen +4 black rectangles

Hi everyone,
Machine Name: PowerMacG3series

A few weeks ago I updated my OS to 10.4 and last week to 10.4.9.
Has been running OK until today. When I started up, I got the
light gray screen with the gray Apple logo and dial-thing. Then
instead of refreshing into the blue screen with the startup progress
bar (the one before the login screen), the computer refreshed
into a light gray screen with four black rectangles (bricks) across
the top of the screen. Haven't seen this described before.

A few days prior, I had installed a Flash Player update.
Permissions were fixed following update and restart was
fine. Restarts on subsequent days were also OK. All
peripherals were disconnected one-by-one
(USB CD-burner and Firewire external HD) but computer
restart failed as already described.
I did experience a Kernel panic a few days ago - but
restart was OK as were at least 4 subsequent boots:

Any ideas on what might be the problem?

Update:
Reinstall of the 10.4.9 updater using 10.4.0
partition as startup disk resolved the issue,
but Safari crashed whenever it encountered
secure website "https" and it did not do
that with the previous 10.4.9 installation.
10.4.10 did not resolve the problem, but
now running the new Safari and 10.4.11
things seem OK so far.

10.4.9 Startup Prb. No blue or login screen - gray screen 4 black rectangle

Hi -
I originally posted this in the Tiger forum but
other than buying a new computer and updating
Tiger to 10.4.11, which is not a current option,
there were no suggestions.

G3 B&W, 450 Mhz, 704Mb RAM, DVD-ROM Mac OS X (10.4.9) two internal HDs - one running 9.2.2 - other with 10.4.9 and 10.4.0 partitions

Grant:
The four bricks on gray background is a Display/Driver problem of some kind.
What display card are you running?
My first thought was a display problem - but the card seems OK (info below)
because tartups from any disk other than the one running 10.4.9 are OK.
If the driver were bad would one expect to see the
Gray Apple start-up? Do you think reinstalling the 10.4.9 Combo
is the best first approach to resolve the problem?
Thanks so much!

B&W G3 gets Black Rectangle on Boot - Hangs

My B&W G3 will not boot OS X 10.4 anymore. It worked fine before. Now when it boots I get the Apple logo then I get a solid black rectangle in the middle of the screen and it hanges.
I put the 10.4 DVD in the drive and pressed C on boot. It starts to boot from the DVD then bang I get the solid black rectangle.
I took all the cards out except the video card. I droped the RAM to 1 stick (256 MB). No help.
It is booting from an Apple 6 GB IDE drive.
It is a revision 1 board.
I replaced the battery, pressed the CUDA ect.
I put in OS 9.2 CD and tried to boot from it as well. No luck. It hangs as well.
No network is connected.
I tried USB keyboard & Mouse and ADB. No help.
Why am I getting the solid black rectangle on the screen after the Apple logo?
Thanks!
Tony

Black rectangle top right

A semi-transparent black rectangle has appeared top right, just below the menu bar, about 3 inches by 1.5 inches. I cannot drag or resize it but can click throught it to items underneath.I think it appeared as I was upgrading Stuffit Expander to 10.0.2. I have voice-over turned off. A restart has not cured it. Any ideas?

Hi, Richard.
Since you've indicated that VoiceOver is off:
1. If you see a single black rectangle that follows the mouse around, you have enabled the Preview Rectangle for Zoom. The Preview Rectangle appears if you have the following System Preferences > Universal Access > Seeing preferences set:• Zoom On and...
• ...in the Zoom "Options" sheet:• "Show preview rectangle when zoomed out..." selected; and
• have set Maximum Zoom anywhere above the minimum setting, i.e. >1.
If Zoom is not required and On is selected, select Off.
2. Have you used a third-party utility that enables the hidden "Minimize desktop to a box" feature of Exposé? In prior versions of Mac OS X, enabling this hidden (and not ready for prime time) feature could create dead spotson the screen in the region of said "box."
3. An errant Startup or Login Item maybe the cause. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem.
4. I also suggest following these general iMac G5 troubleshooting steps:1. See if your computer's serial number is in the range specified in the "iMac G5 Repair Extension Program for Video and Power Issues" document.
2. Rule out potential hardware problems. Run the Apple Hardware Test that came with the computer. Instructions for doing so will be found in the hardcopy manual that accompanied your computer. For additional details, see my "Apple Hardware Test" FAQ.
3. Check the diagnostic LEDs, a feature of your iMac G5. See "About the iMac G5 diagnostic LEDs."
4. If your iMac G5 will not turn on, see "iMac G5: Troubleshooting when your computer won't turn on."
5. See also the iMac Service & Support site.
6. Check the iMac G5 Discussions for similar reports from other users.
7. As a general check, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
8. If the computer is either under warranty or covered by an AppleCare Protection Plan, don't hesitate to take advantage of your warranty and contact AppleCare.Good luck!

Black rectangles after 10.4.5 Upgrade?

Help! I just did the automatic update to 10.4.5 and now I have black rectangles around many of the field windows, desktop icons, etc. It's especially annoying while using Quark.
If I open a window box, the black rectangle superimposes itself over my layout.
Is anyone else having the same problem?
Can I uninstall 10.4.5 and go back to the former version?

katarina,
Welcome to Apple Discussions.
Mac OS X 10.4: Computer speaks unexpectedly, or a black box unexpectedly appears around a file, folder, or other item: If a black outline (or box) unexpectedly appears around a file, folder, icon, button, or other item when you click it, VoiceOver is probably enabled. Your computer might also be unexpectedly speaking items that you click on.
If you don't want VoiceOver on, turn it off in the Universal Access preference pane, or by pressing Command-F5 (or Fn-Command-F5 if you have an iBook or PowerBook).;~)

Why are iCal alarms coming up with a black rectangle?

Why are iCal alarms coming up with a black rectangle? I'm running 10.3.9 and iCal v. 1.5.2. This started after I did software updates this week.
iMac Mac OS X (10.3.9)

I solved it in my case by going to System Preferences>Internet & Network>QuickTime>Advanced, then clicking the checkbox to Enable Flash. I also had to quit and restart iCal.
I think the Quicktime715 update that recently came out had something to do with it.
It seems that the black box is supposed to be a movie of a vibrating alarm clock, and apparently that movie uses Flash.
I hope this fix works for you too.

Viewing PDF in preview, black rectangles around links

I've created a PDF in Microsoft Word 7.0, the PDF looks great in all applications except Preview on a mac. It would seem that all links in the PDF have a black rectangle around them, this only seems to be an issue in Preview, is this a known issue? As near as I can tell, no other applications seem to be interpreting these links as having boxes around them, this would lead me to believe that the problem does not lay with how the PDF was created.

Hi,
Can you try any other PDF file in Preview (not the one you created)

Black rectangle follows cursor

I just updated to 10.4.8 and when the computer restarted I now have a black rectangle that is centered on my cursor and follows the cursor around the screen. It is just the black outline of a rectangle. Any ideas?

Hi, kmroxo.
This is a bug in the Mac OS X 10.4.8 update. For details and the workaround, see my "Black rectangle appears after Mac OS X 10.4.8 Update" FAQ.

Black rectangle blocking iPad screen

Recently when my iPad died and I went to charge it, it had a black rectangle (with a few colourful lines through it) appearing on the screen. The rectangle blocks all of the content behind it. I can still use the iPad but this huge rectangle takes up about 1/3 of the screen, right in the middle. Does anyone know what this could be?

Black rectangle

How can I get rid of the black rectangle that is usually on the back page arrow or right now it is around the apple at the top of the page? Sometimes it will go around half the stuff on the page. If safari is not open it will go around an icon on the desk top. I have tried restoring my defaults on the mouse and in system preferences.

Hi
It sounds like you've accidentally turned on the Voiceover feature. Go into System Preferences - Universal Access, and turn off Voiceover if it's on.
The keyboard shortcut is cmd-F5 so it's not too difficult to hit it by mistake.
