Computer won't start with 4 GB upgrade

I recently purchased a 4GB upgrade kit for my iMac (24") that had 1 GB. When I installed both new 2GB modules the computer would not start up. When I installed only 1 of the new modules (it didn't matter which one or in what slot) with the original 1 GB module everything worked fine. The computer was showing the 3 GB of memory. Any ideas why the 2 will not work. The modules are Memory Master 2GB PC2-5300 DDR2 which I purchased through Best Buy.

not sure if this will solve your problem but you can try..
look at the battery exchange program if your battery is eligable for the replacement or take it to the local dealer so they can check if your board sound is ok.

Computer won't start with battery in it...

have an Aluminum 15" Powerbook G4. I have had this since 2001, when I bought it. I recently updated to OSX. I hadn't used the computer in months and when I went to try and take care of the computer and update to OS 10.4.5 I encountered a problem. When I turned it on nothing happened. I had to turn it off, hit the reset button and then plug in the computer. THe battery was dead so I expected that. But what happened next puzzled me and still does puzzle me.
I managed to get the computer on by holding in the power button. I heard the familiar start up sound(the sound splash if you will) and when that ended I heard this incredibly loud, white noise coming from my speaker. The noise occured about four times. I was in the room with my wife and mother and they both looked at me like 'what the heck was that?"
Now I thought maybe this was an issue with my one battery so I uncovered my second battery and the same thing happened. It won't start up with a battery in there. I took the battery out and found that when it seemed to turn on just fine, I managed to get online and run a complete update. When it came time for the software required restart the computer started up and didn't make any noise at all.
I guess I don't know what to do now. I ran the diagnostics on the computer, from the disk utility and it seemed to come up clean. I don't mind not having the battery in the computer but I don't always want to fix the date and time and the like.
THis is why I'm posting.
I also noticed tonight, when I was charging up the battery that I had to stop and take it with me someplace. When I went to turn it back on, with the battery in and it plugged in the noise came back on and I had to fix the date and time again.
Thanks to those who post, I really appreciate it.

Computer won't start with iPod plugged in

Hey all,
Just got a brand new MacBook Pro and a 30 gig iPod. When I restart with the iPod plugged into the USB port, the computer sits at the white screen forever and doesn't boot into OS X until it is disconnected. How do I fix this? Thanks!

I don't know if this will fix the problem, but here it is:
1. start the macbook up normally w/o the iPod plugged in.
2. right after u hit the power button hold down the button combination "s" and "command"
3. do not let go until the screen goes black and white text is on it. when the text stops moving there will be a prompt.
4. type the following text WITHOUT QUOTES "fsck -f"
5. then when it is done do that same thing again.
6. then try to exit type the following text WITHOUT QUOTES "reboot"
7. then try to reboot with the iPod connected
if that does not work take it into a apple store.

What does a file folder with a question mark in it mean when the computer won't start?

What does a file folder with a question mark in it mean when the computer won't start?

There are four general causes of this issue:
1. The computer's PRAM no longer contains a valid startup disk setting when there aren't any problems with the disk itself. This can be checked for by pressing the Option key and seeing if the drive appears.
2. The internal drive's directory structure has become damaged. This requires usage of an alternate bootable system to perform the repair.
3. Critical system files have been deleted. This requires usage of an alternate bootable system to reinstall them.
4. The internal drive has died or become unplugged. This is the most likely case if the computer took a sharp impact or there are unusual sounds coming from the hard drive's location.

HELP! Battery drained and now, even with a power plug, computer won't start

My battery drained completely...and I went to charge it. When I plug the power cord in, it shows "green" not "red." When I remove the battery and just plug in the power cord, the computer won't start either.
Anyone encounter this before after a full battery drain? It's very odd.

I had the same green light non-charging problem. Turns out, I had to replace my wall adaptor. A dealer will have a good power supply you can try.

Lightroom 4 crashes when trying to open the slideshow module. I spent over three hours with both Adobe and Apple tech support and we know it is a permission issue but have not been able to get it solved. It started with the last upgrade to 10.8

Back up all data.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
The first step should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
resetpassword
That's one word, all lower case, with no spaces. Then press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Firmware update progress bar appears and computer won't start up

Hi,
I am on OS X 10.6 (the latest developer build, whose build number I can't remember and can't look up because my computer won't start up) and this morning when I tried to start up my computer, it chimed, the apple appeared but then a grey progress bar (like the one that appears during a firmware update) appeared at the bottom of the screen along with the customary spinner. This progress bar didn't update and after 10-ish seconds, it disappeared and left just the spinner. I left the computer in this state for 4 hours and nothing happened. It still starts up in single user mode (but I can't seem to get Open Firmware mode to load) and it starts Windows XP on another partition of my main HD.
When I start it in verbose mode, it says that my catalog B-tree has keys out of order and it is unable to repair them. Also, I get an error message from launchctl: "Bug: launchctl.c:2033 (23930):17: auditquickstart() == 0". Then later on it tells me to convert a few system plist files to launchd (all in the /etc/mach_init.d/ folder). The very last line says "launch_msg(): Socket is not connected".
I would rather not re-install the system, but if I have to, I guess I will. I appreciate any light that anyone can shed on this problem.
Thanks,
Kyle

Yes, they (the third-party utilities) both come on bootable DVD's. As I mentioned, since Snow Leopard was just released in its final version, the developers may be in the process of releasing updates.
Your situation is likely to be a case where the data corruption issue already existed before installing Snow Leopard, and the installation process made the problem more apparent (because something critical was installed where it was affected by the data issue).
It is a good idea to run +Repair Disk+ in Disk Utility on the startup volume before installing a major system update. Actually, I do it before any system-level update.
You should also have a backup (at least of your personal data if not the entire volume), in case something bad happens during a major system upgrade. If you were using Time Machine, the easiest recovery would be to reformat the internal drive and use the Time Machine complete volume restore utility to restore the volume back to the date/time state just before you installed Snow Leopard. Then, after restarting from that restored volume to make sure everything is working, start up from the Snow Leopard installation disc, run Disk Utility and use +Repair Disk+ (just to be sure), and run the upgrade to Snow Leopard again.
If you have a backup of at least your personal data, you may want to reformat the internal drive, install Snow Leopard and bundled apps, install your third-party apps from their original sources, update everything that needs updating, and restore your personal data.
If you don't have a backup, the best bet is to try either DiskWarrior or TechTool Pro. DiskWarrior is very specialized into repairing this type of data problem. TechTool Pro has similar capability, but it is a more general tool with other features.

Mountain Lion update, and now computer won't start up?

Writing this for a friend, as his computer is inop at the moment. Hence this message.
He has a new 27" iMac. He upgraded to Mountain Lion a few weeks ago, and then had intermittent problems with apps unexpectantly shutting down.
Now he did a ML update this morning, and his computer won't start up. It gets to the point of the Apple logo coming up, a progress bar, and then the spinning wheel, but then shuts itself down right afterwards.
A safe boot yields the exact same result.
Any thoughts out there on what he could try to get it up and running again?
Thanks much for any and all help.

Thank you for the fast response.
He was able to get into Disk Utility with the Command and R keys, but when he tried verifying the disk, in red it said 'Invalid Node Structure, volume could not be verified completely'.
He went ahead and verified it anyway, then proceeded to repair it. Howver, it stopped repairing, said it cannot repair, and that he should back up files and reformat the disk.
How can he back up his files? He cannot see a way to do it. Is there anything else he can do besides having to reformat the disk?
This is his first Mac (after much prompting from me to go Mac), and he's afraid he's now lost everything on there.

Deskjet Advantage 3540 (Envy 4500): Computer won't connect with printer during software installation

I just bought this printer and I am trying to install it by using the HP installation CD but I am running into difficulties to complete the process. The problem is that the computer won't connect with the printer (but my printer connects fine with my Wi-Fi network) and installation does not complete.
The HP software installation process appears to go normally (at least no error messages are shown) but when it gets to the part where it asks me how I would like to connect to the printer (Wireless or USB cable) I get an error message when I select Wireless Mode. My printer appears listed but as soon as I select it, a dialog is shown stating that "network installation could not be performed".
Below are the dialogs and what happens (text is in portuguese but you get the idea)
Dialog 1: selecting wireless connection mode
Dialog 2: printer appears in list and I select it
Dialog 3: Error message is shown, no further details
Here are some more facts:
(1) Printer connect fines with my Wi-Fi network: the connection details are correctly shown in its display (Wi-Fi SSID and IP 192.168.0.6) ;
(2) If I go to a web browser in my computer and type in the IP address, I can access the printer's webpage fine;
(3) I've tried uninstalling and reinstalling HP software;
(4) I've resetted my router;
(5) I've executed "HP Print and Scan Doctor" utility and it states my software hasn't been installed (which I don't understand) and it tries to download HP software and install one more time and I get to the error.
(6) If I go to "Start" menu, I can see the HP group is empty (installation only creates icons on my desktop). See picture below:
My OS is Windows 7 64 bit Ultimate (Service Pack 1)
EDIT: I've just discovered the inkjet Advantage 3540 and Envy 4500 appear to be the same printer, each target to a different market.
Help is much appreciated as I tried a lot of things to make this printer work wirelessly with my computer but without success.
Thank you,
Joao Pedro

My mac desktop computer won't start and just beebs

My mac desktop computer won't start it just beens loudly. I don't have any lights showing on the keyboard but can hear the drive switching on. I have unplugged the computer, waited and replugged and waited and then turned it on again without and results. Please help.

I'm having the same, identical problem. It goes into step 2 (backing up process) then it goes back to step one (finding iPad) and it starts over again. It will just keep doing that for 3 or 4 times until it will say "iPad not found". This is so frustrating.

HELP PLEASE!!! Computer won't start up

Help Please!
My computer won't start up, when I click the start up button the light comes only once, sounds click (once) and that's it, no power up.
Because of the age, I knew that the battery could be the reason, so I ordered the exact same battery and replaced it today (following the instructions very carefully). Nothing changed. Then I read about the button for resetting the power management (the one below the ram memory), did that too...and nothing.
I read the manual, it talks about recently installed components (which I have not) and explains the meaning of the numbers of blinks the power light makes with this type of failure, 2 blinks=ram memory, 3 blinks...4 blinks..more than 5 blinks= take it to service.
If somebody could please help me, I would really appreciate
All the best,
Veronica

I had similar problems with my G5 2ghz dual PPC. Mine would turn on, sometimes the startup chime would sound, sometimes not. The fans would run and continue to run faster and faster until I shut it off.
The red light comes on by the way, when the internal plastic shield is not installed or seated correctly.
Anyway, I determined after fooling with the machine for several hours that the symptoms pointed to the video card so, on a hunch, I grabbed a hair drier, pulled the video card and warmed up the video card with the drier. Then reinstalled the video card, hooked up the monitor and hit the power button. Bingo, the machine booted normally. BUT, it would intermittently hang or act odd while running so, I ordered a replacement video card. Installed it and the problem never returned. Sadly someone stole the machine last month but it was in perfect working order at the time:(

Help, computer won't start up

Help, my computer won't start-up now. I downloaded one of those free .swf converter softwares from the net and now I think in the restart process, which should've completed the download like it said, instead it's like I don't have any OS on my computer anymore. And if that doesn't make things worse I was trying to reinstall OS X and it wants to go the net to do that but when i try to it asked my to login to the apple store with the ID i purshased it with and I didn't buy it I downloaded it from a P2P site, so of course the apple store tells me when i login to login with the ID I bought it with so now what, I don't want to lose my file's what should I do anybody got any suggestion. This is what I tried so far.
When it starts up I see the OS X Utilities window
I clicked the the Disk Utility, and clicked my HD and clicked repair.
When it was done it said
The volume appears to be ok.
Volume repair complete.
Updating boot support partitions for the volume as required.
Now what, also I did it again after I held CMD + R
Still when I start up I don't see my hard drive just the OS X Utilities window.
Also when I downloaded the OS X 10.8.5 I saved it on an external but its plugged to my only computer and thats the one I'm having the trouble with, sorry about all the miss spelled words if you can read this and help please do...

Try booting from your system CD, run Disk First Aid from your Disk Utility and repair your permissions.

New HD not recognized - computer won't start

Powermac G4 MDD
Originally had 2 hard drives -- 60GB (jumpered as master) and 40GB (jumpered as slave)
The 40 GB failed and the 60 GB was diagnosed as failing so I purchased used Seagate 160 GB ATA/100 Hard drive
I installed the new 160 GB Hard drive in place of the 40 GB HD and used SuperDuper to clone the still working 60 GB drive. The files were all copied to the drive and the drive showed up on the desktop as a hard drive icon, and it was recognized in the System Profiler. However, I could not select it as the startup drive from the System Prefs window.
I then took out the 60GB drive and replaced it with the 160 GB drive jumpered as cable select and now the computer won't start up (flashing question mark).
What have I done wrong?

I read through all this and still have some trouble. The article says that in Disk Utility if I select the drive a tab named "Partition" will appear at the top of the window among the other tabs. It doesn't.
I noticed some differences in the spec for the 2 drives currently in the machine: specifically, the new 160 gb drive is formatted (right word?) as GUID not AMD as the old drive is. But I can't figure out how to access that "partition" option and make the change. Here are the spec from System Profiler:
