Laptop computer frozen and trying to reboot but will not. How can I quit and restart?

How do I restart a computer that is frozen and tries to reboot and will not do anything else? Is there a way to shut it down to restart. I thought I remember there were some keys to shut down and restart.
We have disconnected the power and any external devics and no CD.

Press down on the Power button and hold it down for 5-10 seconds until the computer shuts down.

Restart your PC. after the PC restarts, bring up your Task manager, and go to the "Processes" tab. Click "Image name" to sort the processes alphabetically.
Now try to launch iTunes.
Does an itunes.exe process appear? If so, does it vanish after a second or so, or does it persist in the Processes tab (even though iTunes itself never shows up)?

That suggests that another application has stashed old QuickTime componentry in your system files.
So just in case we'll go looking for older QuickTime componentry in the most common locations for it to be stashed.
First we'll need to change some view settings.
In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.
Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
If you have a 32-bit version of Windows, open the "System32" folder.
If you have a 64-bit version of Windows, open the "SysWOW64" folder.
What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)

My ipod will not respond to anything. I tried to restore but unable to how can I fix this?

How can I restore this?
The error is an unknown error 1437

I wrote this few years ago, see if this still helps
If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
http://docs.info.apple.com/article.html?artnum=60983
If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
Make sure you do all the following “TRYs”
A. Try to wait 30 minutes while iPod is charging.
B. Try another FireWire or USB through Dock Connector cable.
C. Try another FireWire or USB port on your computer .
D. Try to disconnect all devices from your computer's FireWire and USB ports.
E. Try to download and install the latest version of iPod software and iTunes
http://www.apple.com/itunes/download/
For old and other versions of iPod updater for window you can get here
http://www.ipodwizard.net/showthread.php?t=7369
F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
http://www.apple.com/support/ipod/five_rs/
G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
http://docs.info.apple.com/article.html?artnum=93651
If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
Intermediate Level
A. Try to connect your iPod with another computer with the iPod updater pre-installed.
B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
For Mac computer
1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
5. Eject your iPod and do a Reset
6. Open the iTunes 7 and click “Restore”
For Window computer
Go to folder “My Computer”
Hope you can see your iPod there and right click on the iPod
Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
Now select “Format”
Eject your iPod and do a Reset
Open the iTunes 7 and click “Restore”
In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.

C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
Tips
a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iTunes 7.
b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

Advance Level
A. Diagnostic mode solution
If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
iPod 1G to 3G: "Menu" and "Play/Pause"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
iPod 1G to 3G: "REW", "FFW" and "Select"
iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
B. Format your iPod with a start disk
I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
If none of these steps address the issue, your iPod may need to be repaired.
Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
Or visit your local Apple Retail Store http://www.apple.com/retail/
In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ or ifixit at your own risk
http://www.ipodresq.com/index.php
http://www.ifixit.com/
Just in case that you are at the following situation
Your iPod warranty is expired
You don’t want to pay any service charges
You are prepared to buy a new one
You can’t accept the re-sell value of your broken iPod
Rather than leave your iPod as paper-weight or throw it away.
You can try the following, but again, only do it as your last resort and at your own risk.
Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
Last Resort Level
1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)

2.Press the reset button on the Hard Drive inside the iPod – Suggestion from Kill8joy
http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

Finally, I read a fair comments from dwb, regarding of slapping the back of the iPod multiple times
Quote “This has been discussed numerous times as a 'fix'. It does work, at least for a while. In fact I remember using the same basic trick to revive Seagate and Quantam drives back in the mid to late 1980's. Why these tiny hard drives go bad I don't know - could be the actuator gets stuck in place or misaligned. Could be the platter gets stuck or the motor gets stuck. 'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote

Computer Recognizes iSight in System Profiler, but will not work

So I have a black MacBook and everything works fine except for the built-in iSight. I have tried reseting my computer and even did a factory restore, but to no avail. When I checked the system profiler, it recognizes my iSight. Here is what it says under the USB Device Tree:
Built-in iSight:
Product ID: 0x8501
Vendor ID: 0x05ac (Apple Inc.)
Version: 1.89
Speed: Up to 480 Mb/sec
Manufacturer: Micron
Location ID: 0xfd400000
Current Available (mA): 500
Current Required (mA): 100
When I open iChat or PhotoBooth, the green camera comes on but it displays only black. Obviously the computer knows that I have an iSight camera, but it just will not work. Is there something I can do, or is my camera just broken? Please help me out.

So Welcome to Discussions, jwellie
(0) Have you tried all relevant suggestions from http://support.apple.com/kb/HT2090 ? Did you test iChat and Photo Booth in a new test user account? If you need help creating a test account, see this article:
http://docs.info.apple.com/article.html?path=Mac/10.6/en/8235.html
(1) You post that you "tried reseting my computer". If that means you doubt whether you properly reset your PMU (SMC) per this Apple article:
http://support.apple.com/kb/HT3964
print out the instructions appropriate to you model, study them carefully, and perform the reset again.
(2) Did you disconnect all AV devices (examples: eYeTV, iPods, scanners, etc.) before your tests? If you installed non-Apple software with any of those AV items, have you uninstalled the software IAW the supplier's instructions?
(3) When you did your "factory restore", did you zero (securely erase) your disk before installing the factory software? One zero write is sufficient to be certain there is nothing left on your startup disk that may be causing your problem. If you need help with the procedure, see:
http://docs.info.apple.com/article.html?path=DiskUtility/11.5/en/7090.html
Zeroing the disk will take a long time (hours, depending on the size of your drive), so plan some time.
(4) After zeroing the disk and a "factory restore", did you test iChat and Photo Booth before you added any non-Apple software items? This test will assure that you have not added some third-party item that is causing your problem.

My ipod connects to the computer but will not charge, can you help?

My ipod will not charge. I have tried charging via the mains and via the computer. The computer recognises it but it still won't charge. Any ideas as to what the problem might be?

See the not-charging topic of:
iPod touch: Hardware troubleshooting
Another charging source?
Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and cracked or broken plastic.

Firefox.exe application error, tried uninstalling firefox but will not delete Scriptff.dll says access is denied. so i can't make a complete clean reinstall. how do i fix this?? thanks!

saw in previous questions that to fix this application error, i need to uninstall and do a clean install of firefox. however, Scriptff.dll says that access is denied and can not be deleted from the program files. how can i fix this so i can run a clean install?

Hello cor-el, thanks for your reply. I changed my settings for downloads to desktop and it has appeared on there. When I double click I am asked which program I want to open file. I click firefox and another box "opening install" says I have chosen to open the file which is an application and do I want to save it. This is the only real option so I press save file. I get a box saying this is an executable file which may contain viruses - do you want to run. I press ok and the final box showing C drive file name and desktop appears stating application not found.
This happens the same whenever I try to install.
To my untrained eye the application is not being recognised as an application and I cannot work out how to get it to do that.
My plugin is still showing as out of date.
Is there anything you could suggest. Thanks for your time.

Using Lightroom 4.2 - Windows 8 - Canon 5D Mark II - trying to tether but will not detect the camera

Trying to get my Canon 5D Mark II to tether. It is on the "good" list. But all I can get is "Camera Not Detected". Computer sees it ok. But LR seems to be oblivious.

Further infomation. Computer see the camera when it is connected and switched on. Shows up as "portable Device". Canera also see the computer as instead of shutter speed in the viewfinder it flashes busy. So connection seems quite fine. If curious camera Firmwear is 2.1.2. Puzzled!

Adobe Photoshop Lightroom 3 updates won't work? Also tried DNG converter but will not work either.

Does anyone know how to get the Adobe Photoshop Lightroom 3 to update so you can use it? I can't process raw files with my new Canon SD Mark 3.
It looks like they stopped doing updates.
Next I tried the DNG converter but it was useless. It could not find any of my photos.
SOS - I needed to complete a job with this last night and their site won't help and they finally respond by saying we will get back to you in a few days.

That camera requires at least Lightroom 4.1. There is no update for Lightroom 3 that will support the files from that camera. I'm guessing that you're having the typical problem that new users at the DNG converter encounter. The converter prompts for the *FOLDER*. If you open that folder then the DNG converter will tell you there are no files to convert. Just choose the folder. I know, it's really stupid prompt and method. But it is what it is.

test if it charges with an ac charger

if it's no to both then likely the connector is broken
if it's yes to both thne it's likely your computers itunes install which is the problem

The problem is your friend's music does not belong to you. It is owned by your friend.
I'm afraid you cannot do what you are trying to do. Restoring the iPhone is what you would have to do.
In the future, put your music on the computer and transfer it to the iPhone, not the other way.
