Xul.dll missing will not boot up, I dont want to lose my bookmarks either

Hi,
Firfox will not boot up, I get the xul.ddl file is mising message. I am worried that if I reinstall I will lose all my important bookmarks.
Help!

Download a fresh Firefox copy and save the file to the desktop.
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

MBP will not boot when a USB/USB2 Device is plugged into either USB port.

MBP hangs on the initial Gray Screen when anything is plugged into either of my MBP's USB ports on boot and reboot. I've tried it with a USB mouse, USB2 Hard Drive, USB Memory Stick and USB RF Mouse. It DOES NOT happen when anything is plugged into the Firewire 800 port, only either USB port.
It happens on reboot and a fresh start whenever something is plugged into either of these two USB ports. I've let the gray screen sit overnight, just to see if it would enter the Login Panel. Didn't happen.
As soon as I unplug the USB item, the HD whirls up and a few seconds later the booting continues as normal. I have booted in verbose mode just to see what the system says. It stays on the gray screen, again, until I unplug the USB device. However, the screen does note the following:
"The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 3 of hub @ location: 0x6000000)."
The above error may or may not be related.
........AND BEFORE ANYONE SUGGESTS IT, YES I HAVE ZAPPED THE PRAM and reinstalled the OS from new MBP Install Disks from scratch! Still occurs.
Hope someone can also validate what I've wrote with the newer MBP, as well.
Many Thanks!

I'm having exactly the same problem with my MacBook Pro.
It's either the usb hub or simply the iphone... every time I need to boot my macbook pro I have to disconnect every device. It's getting quite annoying.
The previous 17" Powerbook G4 had no issues.

CPU will not boot up

CPU will not boot up. When the power button is pressed, either from a cold boot, power off or from a reset, the hard drive begins to operate, then you hear 4 beaps a pause of about 5 seconds and then the fan races.

You may have to repurchase some programs if you can't recover their registration codes, etc... Try though some of the data recovery techniques outlined on my backup FAQ*:
http://www.macmaps.com/backup.html
Also try replacing the clock battery.

PowerMac Will NOT Boot up

Last night my PowerMac G5 seemed like it was hung up. I had to shut it off to get it to do anything. It hasn't booted since. I went through all the diagnostic BS, verified the disk, checked the permissions, booted in verbose mode and it end up hanging when it gets to something that said something about CiscoVPN. I have Cisco VPN software loaded on the box. I have used it for months so I'm not sure why all of a sudden it is a problem. So, i brought the PC to the Apple store. Genius could not get it to boot or start in Safe mode either. TOld me to try the Archive and Install. I brought it home and did that. Now it boots but I get no icons or toolbar. I get part of the spotlight toolbar in the upper right. It is about 1/2" long. Nothing happens. Does the same thing if I start in safe mode.
Does anyone have any idea what is going on here? I am getting a little upset with my Mac. Not sure why this machine will not boot. Don't want to lug it to the Apple store again.

Well, I can't say for sure what's wrong. What I would do if it were mine...
Swap out memory chips if you can. If you have four, take out two and see what happens. If it works, one (or maybe even both, but probably not both) of the chips you took out is bad. If it doesn't work, swap out the others. If you only have two, try them in different slots.
If you have an external firewire HD that can boot your Mac, install an OS on that and see what happens. If it works, you're probably looking and a bad HD.
Since there are a lot of other components that could also have failed, there's no telling what exactly it is, but memory and HD's are the most common causes of pain.
You mentioned doing the standard troubleshooting BS - if you haven't pressed the PMU reset button or booted into open firmware mode and doing a reset, make sure you add those to the standard troubleshooting BS bag-O-tricks.
If none of the above work, I'd try backing up my important data, erasing the HD and doing a fresh install.
Good luck,
Jeff

System will not boot up

MB: KT6 Delta-LSR
CPU: XP2500 Barton
GFX: Asus V9520 Magic/T 128mb
RAM: 1028 pc3200 ddr400 (2x512) Geil Branded
HDD: Maxtor 40GB 2mb Buffer
Put it all together formatted the HDD, installed windows, network was working perfectly. (on ASUS via600 board)
Next day turn it on and nothing, zilch not even a flashing cursor top left of screen, dont even boot to DOS. screen is completely blank.
Tested CPU, GFX, RAM and PSU in another base unit and they work fine, yet put them all together and nothing.
1st I thought it was the mainboard so I sent the ASUS board back and ordered the KT6 Delta nice looking board. But still exactly the same problem.
Lights on case are lit all fans are turning ect yet still the system will not boot up i dont even get a flashing cursor top right of my screen.
There is no light with this mainboard for some reason.
All components work when fitted to another mainboard in a different case.
NB: one thing I have noticed is that there are two power sockets on this board,
1. The usual 20 pin socket (which I am connected to)
2. A 4 pin socket near to the CPU (whilst my PSU has a plug that will fit this sockect also, I am unsure as to connect instead of/as well as or leave unplugged.

Like I have stated before, it is the compatibility issue related towards your chip fsb and your memory fsb. I know that not everyone has money to go buy another stick of memory, I don't. But maybe you could exchange from the place you bought and say that it was a mistake? The cheapest route without getting the fsb chip to match the fsb of the memory stick is to get PC2700 memory. Have you tried going for this yet? I'm sure that your motherboard may not be shot, my board didn't get shot after trying to the two different fsb. You have to understand, motherboards are picky when it comes to running the hardware. If there is a conflict, it won't run right, I could run at a lower fsb and get it to work fine, but it wasn't at it's full potential, and I wasn't going to waste my time trying to find the fsb that would work correctly. So, I just let my friend have the stick back. This is why I'm asking you to try a lower speed stick of memory, because I have experienced this. But so far you haven't even seemed to notice my replies, could you take a quick overview of what I have said? Sorry if I come off as rude, just I am taking the time to write these replies and really am trying to help from my knowledge base. I have experienced this type of problem of what you are talking about personally.
Ok, so maybe I might not know it all, seeing that other people replying here have the same mb spec and chip fsb and memory like your trying to run, they might know more when it comes to that area for sure, just I didn't have luck trying to run a faster stick of memory compared to my chip, even though my board could run it, I couldn't get it to work, at all. I would just get a black screen, I thought I shot my GPU. Then I reset CMOS and the bios would flash, then when it would start pulling from harddrive, boom, black screen again. I had my friend tinker with my volt. to the right volts of the memory stick, still couldn't get nothing. This is why I am a little skeptical about you being able to run it at all in the long run. Hopefully you can find a way, maybe it is your manufacturer of your stick, but my conclusion is, if it isn't going to work with one, or two of same speed, try lowering it. Like I said, I tried it on this setup right now, and I didn't have to replace the chip or mobo, or gpu, so those should be fine.

Satellite Pro 4340DVD will not boot up - pci.sys missing or corrupt

I bought a Toshiba Laptop Satellite Pro 4340DVD Model # PS434C-3N152, Serial # Y0018185J, off E-Bay.
The original operating system, Win 98SE has been upgraded to Win XP Pro. No disks came with the laptop.
The laptop crashed yesterday while I was online and will not boot-up.
_Error message reads:_
+The following file is missing or corrupt: System32\DRIVERS\pci.sys.+
Any suggestions on how to rectify this problem will be deeply appreciated. I would very much like to have a users manual for this unit but haven't been able to find one.
Thanks!
Sam

Turns out that the dirty dawg was Anti-Virus 2009 that caused the problem. Managed to get laptop to boot up in "safe mode," found the dirty dawg, deleted it, and the laptop booted right back up.
This issue is resolved!

Macbook Pro Will Not Boot to Retail Snow Leopard

I am a PC tech working on a Macboo Pro mid-2010 15" aka MacbookPro6,2 for an acquaintance (really) and I really appreciate any help/tips on this. As given to me, the MBP was totally non-responsive. Also, the owner does not have the original DVDs that came with the machine nor did she have the power adapter (long story).
Here is the summary: The MBP will not boot to a retail Snow Leopard 10.6.3 DVD; it only gets to the light grey screen with the darker grey Apple symbol and no spinning gear.
Here are the details:
1. After procuring a new AC adapter and installing a new battery, it would boot up and run but displayed an error with Steam startup. It connected to the internet via wifi, launched and ran a video dvd, etc, etc. Looked good except for the Steam error screen.
2. I went to the Steam website and downloaded the current version. After the software installed I did a normal shutdown and restart and the MBP would not boot, just went to grey Apple screen and spinning gear.
3. Booted up in single user, ran fsck -fy which reported "Invalid node structure (4, 24755)" which I understand is not good and it also reported that "The volume Untitled could not be repaired". Just on a whim I ran the fsck a couple more times not expecting anything different and that's what I got - nothing different.
4. Power up with Command R. Goes to grey screen and then tries to boot off of the bad hard drive with previous results.
5. Talked to Apple Care. To make it short, they sold me a retail Snow Leopard.
6. Installed a new blank hard drive (500GB, SATA II, WD Blue) and loaded the Snow Leopard into the Superdrive.
7. Power up and press C. Just goes to grey screen and grey Apple.
8. Power up with Option. DVD is there, click on it to launch, goes to grey Apple and that's all it does.
9. Just for grins, I popped in a Windows 7 Recovery DVD and did the power up/option to launch that and the MBP actually loads the Windows files and screen but it will not proceed because Win7 recovery doesn't recognize the MBP. At least the DVD worked.
10. Installed a different new blank hard drive and tried to launch Snow Leopard install but no dice.
11. Just for grins number two, I tried a remote install on my local network. On initial DVD access, the MBP displays a spinning globe along with the grey Apple, accesses the DVD on the remote laptop three times, but then the spinning globe disappears and everything stops. I left it for an hour and nothing else happens.
That is where I am stuck. I really appreciate any ideas on how to proceed. I can hear Genius Bar already, but was just wondering if I missed any possible steps to take myself.

You should have better luck with the correct build, as you can't use the installs as backward compatible. I also have an older machine that is for the kids, and was upgraded with the 10.6.3 retail disk which will not work with the Mid 2010.
Best of luck, and hope it helps.
If no luck, you may want to investigate hardware issues, as it should boot and install.

IMac will not boot up when printer is plugged in USB

After buying my new iMac (with Tiger) I successfully transfered everything from my old iMac (with Panther) and all was well.
The problem is that when my printer (Canon Pixma MP130) is plugged in on start up, the iMac will not boot up (no gears turning on the white/grey screen). When I unplug the printer from the USB and start it up, it works fine. Its not a super big deal because I can just plug the printer in when I need it. But why does it do this?
I foound on the internet someone else who had the same issues. It was suggested to him to search the printer manufacturers website for updated drivers. I did this, installed them etc..... still no luck.
I am without any mac guru's here in Yellowknife......help!

Hello there,
I hope it is OK to recycle this old thread.  I did not want to create a new one since I am experiencing the exact same issue as the original poster *flying girl* as well as other posters in the following threads:

I have two Macs, a PowerBook G4 and an Intel iMac 20" (Aluminum)--please refer to my signature or profile for the specs of these machines.  Of course, I got the PowerBook before I got the iMac.  I am running the latest version of the Canon MP130 drivers, printer drivers version 4.8.3 and scanner drivers version 12.11.0, on both machines.
When I turn on my PowerBook with the Canon PIXMA MP130 multifunction turned ON and connected via USB to the PowerBook, the PowerBook boots up just fine.  I have even experimented with both a USB hub and a direct connection to the Canon MP130, and the PowerBook boots fine in both instances.
However, when I turn on my iMac with the Canon MP130 turned ON and connected via USB to the iMac, the startup tone plays, and then the iMac hangs at the blue/gray solid screen--it does not even show the Apple logo or the spokes--that is, until I turn the Canon MP130 OFF.  When I turn it off, the Apple logo appears, the spokes move, and my iMac boots up just fine.  And as long as the MP130 is OFF, I can boot the iMac fine from scratch too.
I tried starting in verbose mode (⌘V) and single-user mode (⌘S), and the gray/blue screen still appears after the startup tone plays; again, if I turn the Canon MP130 OFF, the rest of the boot sequence resumes as normal, and only then do I get to see the descriptive text for those startup modes.  But the text goes by so fast that I miss most of it--I did manage to catch something that said something like "get full config descriptor = NULL," but I am not sure if that was the exact wording.  I would need a good camcorder or even just a digital camera or another device to capture exactly what the screen says in verbose mode.  If I had those options, I would post pictures here.
I was thinking about contacting Canon, but since the issue happens on one Mac only, I figured they would tell me that it is a problem with my Mac.  So hopefully posting the information here is OK.
Another key feature is that the Canon MP130 has a built-in card reader.  I made sure that my Startup Disk preferences were set to boot from the system drive, and they still are.  And I have reset the SMC and PRAM on the iMac.
I would like to mention the following link:
http://www.ehmac.ca/anything-mac/50389-intel-imac-wont-boot-when-canon-printer-p lugged.html
If you go to page 2 on that above thread, it shows one user who allegedly physically disconnected the card reader connection from the inside of the Canon MP130 (I would NOT recommend that myself).  I just wonder if there is a more feasible resolution to this issue.
Does anyone else experience the same issue with other printers or multifunctions?  Also, why does the issue occur only on my Intel iMac 20" (aluminum), and NOT on my PowerBook G4?
Please let us know about your experience as it seems many of us are at a loss for a solution.
Thank you very much for your help; we await!  :)
Cya!

My 2009 macbook pro will not boot up I have installed Yosemite

My laptop will not boot up. I have tried to repair the disk but I keep getting error mesages that the edisk needs to be installed because files are missing.

Do a backup. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

G5 will not boot from internal hd

I have T-Booted this iMac G5 into FW Target Mode
Reformatting the HD from another iMac (INTEL)
Installed OS X 10.5 again
Booted the iMac (INTEL) off this iMac G5's HD OK
Setup the system fine and it all works OK.
BUT if I then try and get the iMac G5 to reboot off it's own internal HD it does not see the system.
Also, the iMac G% will not boot of the 10.5 Universal Install DVD?
What am I missing here please ?

Hi Ralph,
I could not see any internal HD by starting up with 'option' held down, only the install CD (10.4 CD 1 this time).
I rebooted into 10.4 Install CD1 and Used Disc Utility .. and there was the drive, but with two partitions on it ??
I formatted the internal HD drive and made just one Partition.
I rebooted, this time to a 10.5 Installer and just get to a blue screen.
So...
Seems that HD is there and OK?
This iMac G5 does not like a 10.5 system DVD
This iMac G5 does like a 10.4 system CD set 01,02,03,04...
This iMac G5 does have a SuperDrive listed on it's foot BTW.
What next do we think... just put 10.4 on it?...

While upgrading my 3,2 8 core power Mac , it will not boot. Going from 10.8.3 to 10.8.4. There is no visible video after chime. I need to get up and running ASAP. Could the video drivers have not loaded. Please help and thank you. Ps. Main drive ssd.

The Mac will not boot to a cd, Mac or disk warrior.
It will run for 10 minutes with no video, then shut itself down.
I've attempted Cd boot, zapping Pram, safe mode,
My new Dell monitor power light pulses as if no video is present
Wondering if the vid. driver did not load during update?
Can't seem to light one pixel, no matter what.
Thanks.

Thanks for reading and responding

Update on this issue. I replaced the video card with an old one that I had and it boots fine.
Question, if a driver were missing from the update process, would I see anything on the screen at all. I had pure black as if no signal was carried to the monitor. I'm trying to rule out hardware failure, as this card is 1.5 years old.
thanks!!!

T410 Windows 7 Recovery Media 64bit from Lenovo will not boot

I have been sent 4 sets of Windows 7 Recovery Media from Lenovo over the past week and a half. These DVDs are unusable as they will not boot because they were created as non-bootable DVDs. When looking at the DVDs, they all just have 1 file on them - 0A44006.dvd. I was sent a set of the 32bit version and it has multiple files on it with Bootmgr and 6 directories and will boot just fine. The 64bit DVDs obviously were created and replicated without any of these files to make it a bootable DVD. Can someone from Lenovo (Morristown, NC) find out why and fix these DVDs. The support center in Atlanta can only order another set from Morristown and I keep getting bad DVDs.
Solved!
Go to Solution.

There's probably a way to make a bootable DVD out of that file. If all have the same file you will probably still be missing a DVD or two - unless the contents of the files in a set are different. Then again if it "1 of 1" is correct this may be all you need.
You can try a couple of things (just pulling this out w/out much thought...):
Use 7zip and extract the contents to <somewhere> and then burn that as a DVD. Probably still won't be bootable, though. Or just use your favorite image burning tool (nero, Win 7's built in burner, whatever) and burn that file as an image.
That may require renaming xxx.DVD to xxx.ISO. This presumes it is an ISO. Since 7zip can unarchive it, it probably is an ISO - or something very similar. 7zip may actually be able to tell you what its format is.
Let us know how that goes if you give it a try.

Replaced Optical Drive now Mac book will not boot up

I bought a second hand Mac Book Pro A1150 model. It did not have an optical drive so I bought one, installed it and now my Mac Book will not boot up. When I take the drive out the Mac Book boots up fine. I was told that the optical drive although used was tested and work when it was shipped out. I'm a little new to Macs but not new to working on computers. Is it common for a possible defective optical drive to casue a Mac Book pr to not boot up or does this sound like an issue with the optical drive cable, or possibly the logic board?

That is true. I cannot think of any way to test the Optical Drive without swapping it into a known correctly operating MBP.
A thought which probably may not be an issue. When I installed an Optical Drive in my old (2006) MBP, I remember seeing in the instruction manual an item called a grounding pad (which looked like a tiny steel brillo pad with out soap) which was missing in mine. The MBP worked and I essentially ignored it. Perhaps that may not be case with your situation.
My thoughts are that the Optical Drive is malfunctioning and the cause of your problem. Perhaps you should consider getting a new replacement from OWC. But that entails a $100 risk with no guarantees of success.
Ciao.

2009 Mac Pro will not boot up under Windows

I have an Early 2009 Mac Pro system (Mac Pro 4,1) and I've had this system for 3 years already and have been working under OS X with this system ever since I purchased it.
However, when I tried to boot off my Windows disk, something very interesting happens. The Mac Pro WILL NOT boot up off the Windows disk or a known working Windows partition if two monitors are connected. Upon holding down the option key and selecting the Windows partition, I will get a black screen on one monitor (the one connected via Mini Displayport) and the other screen receives no signal and will enter standby and the system is halted. It does not respond to keystrokes, there is no hard drive activity, no measured power increase on the UPS, no apparent network activity, nothing. The only way to exit this scenario (from what I can tell) is to power off the machine, disconnect the display on DVI, power on the machine again, select the Windows partition wait for the system to reach the login window and reconnect the DVI monitor (at which time Windows recognizes it immediately and the system works fine again).
My question to the community is, does anybody know why this is happening and is there a known fix for this? Quite frankly, having to disconnect a monitor just to restart is very tedious and frustrating.
I have two Samsung P2350 monitors attached to an ATI Radeon HD 4870 (512MB, from Apple). One is monitor is connected via directly DVI and the other is using a Mini Displayport to DVI adapter. Both monitors work fine under OS X with no issue. At first, I thought that this may be a driver issue on the Windows side and after installing all the latest updates and drivers the issue is still apparent. From what I can tell, this doesn't seem like a software issue but rather a firmware or EFI issue as this happens before Windows even loads.
If anyone knows of a fix or what to do in this situation, or if you are also having this issue, I would love to hear your input!
Thank you!
For the record, I am running all the latest software builds on the OS X side (10.7.4, not that it would really matter at this point). I have also disconnected all unnecessary equipment in a trial and error scenario but the results are still the same.
The system passes all ASD testing.
The full specification of the computer and all connected equipment are as follows:
2009 Mac Pro (4,1) 8-Core
2x Intel Xeon Nehalem 2.66GHz Quad-Core CPUs
16GB DDR3 ECC 1066MHz RAM (Apple Branded)
Two OWC 120GB SSDs (One for OS X, the other for Windows 7 x64) - These are in place of my optical drives.
4x 2TB WD Black Hard drives for storage.
Two Samsung P2350 Monitors connected via DVI. (One using a Mini Displayport to DVI adapter).

In Windows I am using the latest (12.4) Catalyst Software Suite, 64 bit of course, downloaded directly from AMD's site after installing the drivers from Boot Camp.
As for installing Windows I used an original (not burned) installation media (Disk is in a pristine condition). And yes, Windows is fine, the problem just seems to be getting the system to boot up Windows with that second monitor. However if the "problem monitor" is disconnected the system boots fine 100% of the time and connecting it later after booting the system will still operate properly.
For the sake of arguement I swapped monitor cables and connected the "second" monitor to the mini displayport adapter to verify that it wasn't a cabling issue and I'm still yielding the same issues.
As for GPU testing, I've played games (Crysis, Grand Theft Auto IV, Battlefield 3, etc.) and I've had no issues with the card or stability.
You would think that Apple would try to find a fix for this, especially considering the caliber of this machine.
