I have error C0000034 applying update operation 460 of 41831 (generalize XML). All I did was turn my idea pad on. It never resolves and I have tried turning my laptop off and restarting. Any ideas


Restart your computer & start tapping f/8 immediately and keep tapping until black screen comes up. Use the arrow keys to select safe mode the press enter. It will start up in safe mode in each corner, the icons are all out of shape and a help window will open. Close that window. Then go to: Start, Accessories, System Tools, right click System Restore & send to desk top.(The reason to do that will be to use it easier ANYTIME you have a problem.) Then do a system restore back to a time before you had the problem. That should resolve it. If not you will have to do a Recovery after saving everything you want to keep on a Flash Drive. On start, type recovery & go there & follow directions.

It seems that your OS has registry problem. There are only two ways to fix it:

1) Re-install your Windows with Re-partition your drives (In that case you have to take backup of your all data.)

2) Start PC in safe mode and download Reginout and run its all tools to fix your OS registry.

Computer won't start up correctly


Considering you have tried the Safe Boot mode to correct this, try to resolve this from the hardware side:

Procedure #1:

Here are some steps you can try to resolve the issue:

• First, hold in your power button for approximately 10 seconds to do a hard shutdown, if you have not already turned your Mac off.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)

• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

• Now, hold the keys down until the computer restarts and you hear the star tup sound for the third time.

• Release the keys and allow the Macbook to start up.
If the iMac still does not start up to your Desktop correctly, go on to the next procedure:
----------------------------------------------------------------------
Procedure # 2

-PMU RESET-

The Power Manager is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Disconnect all the connections going into the Mac except for the Power cord.
• Once all connections have been disconnected, remove the power cord from the iMac.
• Wait 1 minute.
• Reconnect the keyboard, mouse and power cord back into the computer.
• Press the Power button to restart the iMac computer.

• Observe if it starts up to the main desktop this time.
If it does not however, you may have an issue with your current Mac OS X directory or the issue could be hardware related.
-----------------------------------------------------------------------
Here is a comprehensive reference for you regarding Additional Troubleshooting for Blue, Gray screen issues and more, that you can also review:
Apple Support Link:
Startup Issues for Macs
----------------------------------------------------------------------
If all else fails, you may need to visit your local Apple retail store Genius bar or local Apple-authorized service center in order to have your iMac at least diagnosed to find out what the core issue is.

When you turn the comuter on, it just shows the


--SAFE BOOT MODE--

I am going to have you take your Mac into Safe Mode to see if we can't remove a possible folder(s) that may be affecting your Mac's start up function.

Try these steps:

• Reboot your Mac
• Upon restarting your Mac, press the Shift key.
• Hold the Shift key until you see a White Screen with Gray Apple icon and eventually a spinning gear.

• When you see the Spinning gear, release the Shift key.

• Allow the Mac to continue booting up. Also this may take a little while
(NOTE: this may take anywhere from 5 to 15 minutes to load to the Safe mode screen depending on the performance of your Mac, but if it exceeds this time, shutdown your Mac and try just once more. It may have just frozen up the first time around for you.)

• You are going to enter the Safe Mode (which looks like your main desktop environment - the only difference is certain start up items are disabled.)

• Once within the Desktop in Safe Mode
• From the Finder Menu, click Go> Go to Folder
• Type in this line: /System/Library/StartupItems
• This path, is going to take you to the System Library folder which has all of your Mac OS X StartupItems.

• Remove all of those folders to the Trash.

*Reboot your Mac normally and see if you can access your normal User desktop environment.

This should help get your iMac G4 back up
and running.

Regards,

My computer wont start up


First try pressing F2 at start up to see if you can get to setup. Also pressing F12 may get you a boot menu. If cd is already set as first boot you may get a chance to boot from a Windows cd. The idea here is to get to a minimal Windows configuration like setup or safe mode (F8) to see if this is a hardware or operating system fault. Two common issues with eMachines are power supply problems where repetitive reboots can actually fry the motherboard or if the PC has a few years use the CMOS battery. Steve Medley

Getting blue screen after start up


Try booting up to the recovery CD, it sounds like a software conflict error that is locking up your computer.

Try 1st if you can get into safe mode (hitting F8 when you first apply power to the computer, till the safe mode screen comes up)

Then try booting up to the last known good configuration (same F8 different selection on screen)

THEN try the recovery CD.
