Okay will copy what I said on original thread to here too,,,,
Download the guided help files from the links from microsoft and stick them on a floppy or cd and boot into safe mode by clicking F8 till you see the boot options, you can also try booting in safe mode with network support, that will allow you to use the internet then and to download the files to that pc without having to copy it to a cd or floppy. run the guided help and see if that helps you to get back into normal mode with usb support to copy all your files off that pc, then do a complete restore from the original xp disk.
I would go threw the options of troubleshooting a bad startup in normal mode but I have a feeling this way of doing it for you will be easier because it saves you alot of time and you also get a clean windows install after, it could be many things causing the bad startup, for example bad drivers to some nasty running on your pc thats messed up the registry.
So give that a go and see how it goes ;) try the corrupted registry fix 1st and see if that helps if not try the clean boot option.
Only other option if these fail and you can't get xp to start with usb support to copy over your files is to make a new directory on the drive call it MYDATA or anything you like in the C:
then copy all your files to that folder, make sure you have everything and then you can just reinstall xp over the old install and the folder will remain there called MYDATA aslong as you dont make the install disk format the drive and if its a disk that is not a real xp disk but a disk that came with the pc that was special for it, you will lose all the data, they normally format the drive. In this case you will need to take the hard drive out of that pc and stick it in a working pc and copy all your files off it. SO step with care if its not a original xp disk from misrosoft but a disk that came as a restore disk for the pc.
There is one more option you can try sticking linux on a cd and boot from that and then copy everything over to the usb drive. Not sure you know how to use linux. Try these things under this 1st and then we can try other options if these fail. Good luck.

This article describes how to recover a Windows XP system that does not start because of corruption in the registry. This procedure does not guarantee full recovery of the system to a previous state; however, you should be able to recover data when you use this procedure.
Warning Do not use the procedure that is described in this article if your computer has an OEM-installed operating system. The system hive on OEM installations creates passwords and user accounts that did not exist previously. If you use the procedure that is described in this article, you may not be able to log back into the recovery console to restore the original registry hives.
You can repair a corrupted registry in Windows XP. Corrupted registry files can cause a variety of different error messages. See the Microsoft Knowledge Base for articles about error messages that are related to registry issues.
This article assumes that typical recovery methods have failed and access to the system is not available except by using Recovery Console. If an Automatic System Recovery (ASR) backup exists, it is the preferred method for recovery. Microsoft recommends that you use the ASR backup before you try the procedure described in this article.
Note Make sure to replace all five of the registry hives. If you only replace a single hive or two, this can cause potential issues because software and hardware may have settings in multiple locations in the registry.

Manual steps to recover a corrupted registry that prevents Windows XP from starting
The procedure that this article describes uses Recovery Console and System Restore. This article also lists all the required steps in specific order to make sure that the process is fully completed. When you finish this procedure, the system returns to a state very close to the state before the problem occurred. If you have ever run NTBackup and completed a system state backup, you do not have to follow the procedures in parts two and three. You can go to part four.
Part one
In part one, you start the Recovery Console, create a temporary folder, back up the existing registry files to a new location, delete the registry files at their existing location, and then copy the registry files from the repair folder to the System32Config folder. When you have finished this procedure, a registry is created that you can use to start Windows XP. This registry was created and saved during the initial setup of Windows XP. Therefore any changes and settings that occurred after the Setup program was finished are lost.
To complete part one, follow these steps:
1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted to do so.
2. When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
3. If you have a dual-boot or multiple-boot computer, select the installation that you want to access from the Recovery Console.
4. When you are prompted to do so, type the Administrator password. If the administrator password is blank, just press ENTER.
5. At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:
md tmp
copy c:windowssystem32configsystem c:windowstmpsystem.bak
copy c:windowssystem32configsoftware c:windowstmpsoftware.bak
copy c:windowssystem32configsam c:windowstmpsam.bak
copy c:windowssystem32configsecurity c:windowstmpsecurity.bak
copy c:windowssystem32configdefault c:windowstmpdefault.bak
delete c:windowssystem32configsystem
delete c:windowssystem32configsoftware
delete c:windowssystem32configsam
delete c:windowssystem32configsecurity
delete c:windowssystem32configdefault
copy c:windowsrepairsystem c:windowssystem32configsystem
copy c:windowsrepairsoftware c:windowssystem32configsoftware
copy c:windowsrepairsam c:windowssystem32configsam
copy c:windowsrepairsecurity c:windowssystem32configsecurity
copy c:windowsrepairdefault c:windowssystem32configdefault
6. Type exit to quit Recovery Console. Your computer will restart.
Note This procedure assumes that Windows XP is installed to the C:Windows folder. Make sure to change C:Windows to the appropriate windows_folder if it is a different location.
If you have access to another computer, to save time, you can copy the text in step five, and then create a text file called "Regcopy1.txt" (for example). To use this file, run the following command when you start in Recovery Console:
batch regcopy1.txt
With the batch command in Recovery Console, you can process all the commands in a text file sequentially. When you use the batch command, you do not have to manually type as many commands.
Part two
To complete the procedure described in this section, you must be logged on as an administrator, or an administrative user (a user who has an account in the Administrators group). If you are using Windows XP Home Edition, you can log on as an administrative user. If you log on as an administrator, you must first start Windows XP Home Edition in Safe mode. To start the Windows XP Home Edition computer in Safe mode, follow these steps.
Note Print these instructions before you continue. You cannot view these instructions after you restart the computer in Safe Mode. If you use the NTFS file system, also print the instructions from Knowledge Base article KB309531. Step 7 contains a reference to the article.
1. Click Start, click Shut Down (or click Turn Off Computer), click Restart, and then click OK (or click Restart).
2. Press the F8 key.
On a computer that is configured to start to multiple operating systems, you can press F8 when you see the Startup menu.
3. Use the arrow keys to select the appropriate Safe mode option, and then press ENTER.
4. If you have a dual-boot or multiple-boot system, use the arrow keys to select the installation that you want to access, and then press ENTER.
In part two, you copy the registry files from their backed up location by using System Restore. This folder is not available in Recovery Console and is generally not visible during typical usage. Before you start this procedure, you must change several settings to make the folder visible:
1. Start Windows Explorer.
2. On the Tools menu, click Folder options.
3. Click the View tab.
4. Under Hidden files and folders, click to select Show hidden files and folders, and then click to clear the Hide protected operating system files (Recommended) check box.
5. Click Yes when the dialog box that confirms that you want to display these files appears.
6. Double-click the drive where you installed Windows XP to display a list of the folders. If is important to click the correct drive.
7. Open the System Volume Information folder. This folder is unavailable and appears dimmed because it is set as a super-hidden folder.
Note This folder contains one or more _restore {GUID} folders such as "_restore{87BD3667-3246-476B-923F-F86E30B3E7F8}".
Note You may receive the following error message:
C:System Volume Information is not accessible. Access is denied.
If you receive this message, see the following Microsoft Knowledge Base article to gain access to this folder and continue with the procedure:
309531 (http://support.microsoft.com/kb/309531/ ) How to gain access to the System Volume Information folder
8. Open a folder that was not created at the current time. You may have to click Details on the View menu to see when these folders were created. There may be one or more folders starting with "RPx under this folder. These are restore points.
9. Open one of these folders to locate a Snapshot subfolder. The following path is an example of a folder path to the Snapshot folder:
C:System Volume Information_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}RP1Snapshot
10. From the Snapshot folder, copy the following files to the C:WindowsTmp folder:
* _REGISTRY_USER_.DEFAULT
* _REGISTRY_MACHINE_SECURITY
* _REGISTRY_MACHINE_SOFTWARE
* _REGISTRY_MACHINE_SYSTEM
* _REGISTRY_MACHINE_SAM
11. Rename the files in the C:WindowsTmp folder as follows:
* Rename _REGISTRY_USER_.DEFAULT to DEFAULT
* Rename _REGISTRY_MACHINE_SECURITY to SECURITY
* Rename _REGISTRY_MACHINE_SOFTWARE to SOFTWARE
* Rename _REGISTRY_MACHINE_SYSTEM to SYSTEM
* Rename _REGISTRY_MACHINE_SAM to SAM
These files are the backed up registry files from System Restore. Because you used the registry file that the Setup program created, this registry does not know that these restore points exist and are available. A new folder is created with a new GUID under System Volume Information and a restore point is created that includes a copy of the registry files that were copied during part one. Therefore, it is important not to use the most current folder, especially if the time stamp on the folder is the same as the current time.
The current system configuration is not aware of the previous restore points. You must have a previous copy of the registry from a previous restore point to make the previous restore points available again.
The registry files that were copied to the Tmp folder in the C:Windows folder are moved to make sure that the files are available under Recovery Console. You must use these files to replace the registry files currently in the C:WindowsSystem32Config folder. By default, Recovery Console has limited folder access and cannot copy files from the System Volume folder.
Note The procedure described in this section assumes that you are running your computer with the FAT32 file system. For more information about how to access the System Volume Information Folder with the NTFS file system, click the following article number to view the article in the Microsoft Knowledge Base:
309531 (http://support.microsoft.com/kb/309531/ ) How to gain access to the System Volume Information folder
Part Three
In part three, you delete the existing registry files, and then copy the System Restore Registry files to the C:WindowsSystem32Config folder:
1. Start Recovery Console.
2. At the command prompt, type the following lines, pressing ENTER after you type each line:
del c:windowssystem32configsam
del c:windowssystem32configsecurity
del c:windowssystem32configsoftware
del c:windowssystem32configdefault
del c:windowssystem32configsystem
copy c:windowstmpsoftware c:windowssystem32configsoftware
copy c:windowstmpsystem c:windowssystem32configsystem
copy c:windowstmpsam c:windowssystem32configsam
copy c:windowstmpsecurity c:windowssystem32configsecurity
copy c:windowstmpdefault c:windowssystem32configdefault
Note Some of these command lines may be wrapped for readability.
3. Type exit to quit Recovery Console. Your computer restarts.
Note This procedure assumes that Windows XP is installed to the C:Windows folder. Make sure to change C:Windows to the appropriate windows_folder if it is a different location.
If you have access to another computer, to save time, you can copy the text in step two, and then create a text file called "Regcopy2.txt" (for example). To use this file, run the following command when you start in Recovery Console:
batch regcopy2.txt
Part Four
1. Click Start, and then click All Programs.
2. Click Accessories, and then click System Tools.
3. Click System Restore, and then click Restore to a previous RestorePoint.

If your computer is not starting normally, or if you receive errors when you start your computer that you cannot identify, you could consider performing a "clean boot." This operation starts the computer by using a minimal set of drivers and startup programs. This can help you troubleshoot the problem.
This article describes how to configure Windows XP to start by using a clean boot and then how to return Windows XP to a Normal startup type.
After you configure Windows XP to use a clean boot, some programs may not work as expected. When you return Windows XP to a Normal startup type, the programs work again.
This article is intended for a beginning to intermediate computer user.
You may find it easier to follow the steps if you print this article first.
