Uninstall norton causes computer not to start up

I have just bought a toshiba all in one PX30T-01Q today and trend security software. When I tried to install trend it says that norton is incompatible with trend. It asked if I wanted it uninstalled. I clicked yes so it went about uninstalling it. But then my screen freezes. I had to turn it off. Now I cant even start up my computer. HELP!!

This is the site for U.S. Models only and yours appears to be an Australian model. Your support including Tech Support phone numbers can be found HERE. The first thing I would do would be take it back where I bought it. If that is a problem, then call Tech Support.
One thing you might try before doing all this is to turn the machine on and if it freezes as before, hold down the power switch for 10 seconds or until all lights are out and the fan stops. Then turn it on again. Good Luck!

Computer not fully starting up

I have a PowerMac G5, and just recently my computer will start up to the gray screen, yet it will remain there, and usually around 30 seconds later, my fans start blowing like crazy. I have shut off my computer and rebooted it with several different methods: holding down command-V or rebooting the pram my holding down command-option-p-r until the tower restarts but it will all inevitably go back to where I first started- at the gray screen frozen, with my fans making more noise then ever. Any suggestions? I'd really appreciate it. Thank You!!!

what would be some reasons why my hard drive/logic board would start dying out of nowhere? Are there any solutions?
Not out of nowhere really, as we ourselves are set to expire at sometime... so is everything else, including Computers, some go longer than others.

What causes Firefox not to start and at those times I get this message: Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

I am using Windows 7 Home Premium 64 bit. I do not recall the problem occurring when Windows 7 was first released. This has been happening for several months now with all versions of Firefox. 3, 4, and 5. I have searched online for a solution to this problem. I have tried every fix listed here and online that I could find. The problem remains. Does anyone have a fix for this?

The following may not completely eliminate having to terminate Firefox through the Windows Control Panel but it will come very close.
'''Plug-in and tasks started by Firefox may continue after attempting
to close Firefox''' The "X" in the upper right-hand corner closes the
Window (same as Ctrl+Shift+W) but even if it is the last Firefox window,
it does not necessarily close Firefox .
The only '''proper way to exit Firefox''' is to use '''Exit''' through the
File menu, not the "X" in the upper right corner of last Firefox window.
In the Beta that would be Alt+F then X
* '''Firefox hangs''' | Troubleshooting | Firefox Support <br>http://support.mozilla.com/en-US/kb/Firefox%20hangs#w_hang-at-exit
Use the '''Windows Task Manger''' to remove all running firefox.exe in the "'''Processes'''" tab of the Windows Task Manager, then restart Firefox.
If Firefox will still not start, remove the parent.lock file from the profile which is created each time Firefox is started to prevent other Firefox tasks from running, see<br>

'''Avoiding Problems with close/restart''' ''choose either extension''
:Use to close and restart Firefox after enabling or disabling an extension, switching to a new theme, or modifying configuration files, then you don't have to worry about delay or have to look in the Task Manager to see if Firefox is closed yet.
Both extensions use the same keyboard shortcut "'''Ctrl+Alt+R'''" or a file menu option.

10.4.8 update causes MacBook not to start

Sits on the spinning wheel after numerous attempts to restart. Had no problem until I installed the update. Is there anything good in ths update? If so, what?
How do I go back to 10.4.7?

My Macbook also will not boot, though it did fine after the update (yes, it did restart twice). The freezing started many days later when a different user logged in. Immediately, beachball. Now it does it within 12 seconds of displaying the login screen. coreservic jumps to 100% cpu usage and the system beachballs. I have remote login enabled so I can troubleshoot this type of thing, but in this case there's nothing that can be done.
I've isolated it, I think, to an issue with the aiport. I can Safe Boot and do everything just fine, until the airport is enabled / attempted to be configured. Deleted all airport and network related prefs files manually via ssh, still no dice. So I figure I'll go back to my 10.4.7 SuperDuper backup...but..get this:
I cannot drag disk images in Disk Utility into the Restore window (yes, I'm booted from the startup disk). All mouse clicks are interpreted as a drag-select, and I am unable to move my source or target into the dialog, and swift thinking Apple put no alternate way to access them via a file browser dialog. Typing in full paths to the Volumes still will not enable the "Restore" button. So wth do I do now?

New 6534 pattern generator causes computer not to boot

Critical: Adding session-config to web.xml cause application NOT to start

I added the <session-config> element under <web-app> in web.xml:
<session-config>
<session-timeout>30</session-timeout>
</session-config>
Now the app won't start!
The reason: the built-in sun app server removes context-root attribute from <web-module> element in domain.xml when the app tries to start!
Please fix this ASAP, guys!

I placed it in the wrong place. After following the instructions contained in the Technical FAQ (below), it worked.
Add the following element in your web.xml file, placing it after the mapping for the error servlet and before the welcome file list:
<session-config>

<session-timeout> 60 </session-timeout>
</session-config>

With Windows Vista, the most recent Itunes update 1/30/2014 has caused Itunes not to work, with a Mscvr80.dll not found error. Uninstalled all Apple programs, and installed fresh Itunes. Same problem. Tried to reinstall using an older install exe nogo

Recent ITunes update has caused ITunes not to work. Tried uninstalling all Apple products and reinstalling fresh. Still doesn't work. Tried reinstalling from an old install.exe. Install went nicely but program won't start as it says it can't open the library file.

Now that I have no way of accessing any of the products I have purchased from ITunes, I will most certainly never use ITunes again for any reason. Why throw good money after bad? I will use another MP3 player that is not as cumbersome or proprietary.
Lesson learned.

How can I remove the autorization from my old computer when it is broken and can not be started?

my old computer has broken down and therefore I got a Macbook. Then I wanted to synkronize my iphone with Itunes but i can cause i have used all five authorization. How can i remove my old computer which has broken down and can not be started so I can synkronize with my Iphone?

See To deauthorize all computers associated with your Apple ID
on this page -> http://support.apple.com/kb/ht1420
then authorize what you want.

Have you tried to reset preferences? And no you do not have to start Bridge to do this.,
Hold down the Ctrl key and start Bridge. You should get a reset window with 3 options. Choose all 3.

Word has not been started on this computer

I have the Adobe Technical Communication Suite and Microsoft
Office 2007 installed on my office computer. My operating system is
Windows Vista. In RoboHelp HTML, I have been trying to generate
printed documentation through the Single Source Layouts, but I
receive the following error message every time: "Microsoft Word has
not been started on this computer. Launch Word and click the 'Start
using Microsoft Word' option before generating Printed
Documentation again."
I have indeed opened Word--many times in fact--and I don't
see an option for "Start using Microsoft Word," so I'm stumped.
I am an administrator on the computer, and I installed both
Office 2007 and TCS, in that order, on my system.
In attempting to resolve the problem, I have
- Tried to generate printed documentation for both old and
new projects
- Tried generating .doc, .docx, and .pdf files.
- Uninstalled TCS and Office 2007 and reinstalled them, with
Office 2007 first and then TCS.
- Enabled all macros in Word 2007.
- Removed PDFMaker.dot, according to the suggestion on in the
Print Issues section of Peter Grainge's Web site.
None of these attempts has corrected the problem.
Interestingly, though, I can import a Word file into my RoboHelp
HTML project just fine.
If anyone has any suggestions for how to resolve this
problem, I would be most grateful.

I've got it! As you assume, Peter, is has to do with the roaming profile. The RoboHelp templates were in the roaming profile (C:\Users\xxx\AppData\Roaming\Microsoft\Templates - where xxx ist my user name) but in Word they were not activ. I could activate them in Word (in Word-Options / Add-Ins / Manage ... go to) but when I restart Word, they were inactive again.
Now I changed in Word-Options/Extended/General button "path for files" the path for "user templates" and "startup" to directories outside the roaming profile (i.e. c:\robohelp\startup). I copied the RoboHelp Templates (PrintDoc.dot, Style Mapping.dot and RoboHook.wll) to the new "startup"-directory. I started Word and now the RoboHelp templates were active!
ThenI started RoboHelp HTML and tried to generate printed documentation - and now it worked For a short time I could see a message like "waiting for register VBA macros". I think that was the most important thing. But I don't know what happend in the background (couldn't find anything in the registry) Now I changed the path back to my originally roaming profile-directories - and the "printed documentation" still works!
Best wishes
Olaf

I believe, in other cases the start of "RoboHelp for Word" did the same thing - register the VBA macros - Don't know, why it didn't worked in my case

My macbook pro froze last night and I held the power button down to restart the computer. Now the computer will not even start up. Any ideas what may have happened?

RAM INSTALLED BUT COMPUTER NOT STARTED

RESPECTED SIR,
I HAVE G6-2312AX HP PAVILION NOTEBOOK /LAPTOP. WINDOWS 8 INSTALLED IN IT. 4GB RAM ALREADY THERE. NOW I WANT TO ADD 4GB MORE. I PURCHASED 4GB DDR3 1600MHZ RAM AND TRIED TO INSTALL IT. BUT COMPUTER NOT STARTING. KINDLY TELL WHAT TO DO. JAI HIND
This question was solved.
View Solution.

It sounds as if you did not put in a pair of identical memory modules or did not use guaranteed compatible memry modules. You can't use the module that was already there unless the one you are adding is identical in all respects.
Only use guaranteed modules in identical pairs if you want your memory upgrade to work right the first time.

"Apple Mobile Device Support" will NOT uninstall from my computer, so I am still unable to upload iTunes

"Apple Mobile Device Support" will NOT uninstall from my computer so I am still unable to upload iTunes. I have tried it multiple times in multiple ways and after the uninstall always fails. Solutions to this specific problem?

I don't know... A link to the official repair advice is given at the top of my user tip. There was a new build of the iTunes 11.1.4.62 setup file released yesterday which is supposed to install cleanly on any system still back on iTunes 11.1.3.8, however they are still giving the same advice for problem systems that have already been upgraded. I.e. the new installer won't repair a currently borked install.
You can download 7-Zip (free), or a free trial of WinRAR, and unpack the iTunesSetup.exe or iTunesSetup64.exe file into its components, then try installing them individually in alphabetical order (don't try to install SetupAdmin.exe or iCloud.msi). AMDS might not install right now, but you may get a more useful error message as to why not, and you might be able to run iTunes even if you can't update your devices at this stage.

Trying to sync selected (greyed out) contacts to my replacement 4s. Get error messages - computer not setup to sync - override or OK. OK - session could not start. How do I fix?

I have a new replacement 4s. I am trying to set it up. I hate iCloud but need it to sync my calendar to my phone. I mistakenly set it up to sync Contacts too and found out it synced ALL contacts which I do NOT want. I used to use iTunes to sync only selected contact folders (one I call Sync). Others are too sensitive to have on my phone. So I turned off "where is my iPhone", and turned off "Contacts" on iCloud. It said it would delete all my contacts on my phone the next time I sync (using iTunes). So I try to sync my Contacts using iTunes and find that under "Info" on the device tabs my only possible selection is ALL contacts with the "Selected" button greyed out. But even leaving all checked, I get the message "iTunes cannot sync information with the iPhone because syncing has been disabled on this computer (my Mac). Do you want to enable syncing?" I hit the button "Enable syncing" and I get the error message "Syncing cannot be enabled on this computer" with "Override" and "OK" my choices. If I select "OK" I get the error message "iTunes could not sync information to the iPhone (Name) because a sync session could not be started". I can sync my music and my apps but get this stupid message otherwise. What gives and I do I fix this? Thanks

Actually I can't sync anything - no music, photos, etc. And it tries to start syncing as soon as I plug in my iphone and itunes is open. It ends "sync" but hasn't done anything. I have tried deleting lockdown files (per "solution" found here). I have deleted all my backups (per other "solutions"). I have restored my iphone 2x. I have done soft boots of my iphone. My macbookpro 10.9.3. iphone 7.1.1. iTunes 11.2.2 (3).
