PC keeps restarting

All of a sudden my PC keeps rebooting. It will get to the Win XP welcome screen then restart, then restart, then restart ad infinitum.

I have tried to use the safe mode and last known good configuration but to no avail. I am looking to get a newish tower but I need the data on the hard disc that is in my current PC.

I do have an external hdd to back up to when I can get the pc to work.

Any ideas?

Thanks

Getting your data off the hard drive wont/shouldn't be a problem, there are a few ways to do that, but have you any idea what might have caused the reboot problem, did you install anything, software or hardware, lately?

If an old computer check that the air vents are clear of dust and fluff if so inside will also need cleaning out.

No, not installed anything new, and the day before this started I was using the PC normally and it shut down normally as well.

When it did first start, after the first reboot I got the safe mode etc., screen. Tried them all as above, but still keeps restarting.

If rebooting at welcome screen then is probably a corrupt profile.

As you can not get to safe mode then you need to do a repair install.

Repair XP by install over the top of existing system

1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.

2. When you see the "Welcome To Setup" screen, you will see This portion of the Setup program prepares Microsoft Windows XP to run on your computer:

To setup Windows XP now, press ENTER.

To repair a Windows XP installation using Recovery Console, press R.

To quit Setup without installing Windows XP, press F3.

3. Press Enter to start the Windows Setup.

To setup Windows XP now and Repair Install , press ENTER.

DO NOT choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console).

4. Accept the License Agreement and Windows will search for existing Windows installations.

5. Select the XP installation you want to repair from the list and press R to start the repair.

6. Setup will copy the necessary files to the hard drive and reboot.

Do not press any key to boot from CD when the message appears.

Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.

That is good, but I don't have an XP disc. My PC is an old ME machine upgraded to XP Pro by having a new motherboard installed. Since then it has been and had a new HDD installed, as far as I know the old disc was cloned and then put onto the new disc.

Restore XP

Boot to the command prompt and type:

Press Enter and follow the on-screen prompts to restore to an earlier date/time

if will not boot to command prompt then:

Start Windows Setup and press R to access the recovery console. Select your Windows installation, then type the administrator password – press Enter if there isn't one.
Now enter the following commands:

CD C:\
CD "system volume information\_resto~1"

You'll see a list of restore point folders with names such as RP1, RP2 and so on. Pick the restore point you wish to use, using the folder date stamps to guide you. Enter the commands:

CD RPx (the restore point you chose)
CD SNAPSHOT

This takes you into the folder containing the restore point snapshot files. Copy the Registry backups so that they overwrite the existing Registry files.

COPY _Registry_machine_system C:\Windows\System32\Config\System
COPY _Registry_machine_software C:\Windows\System32\Config\Software
COPY _Registry_machine_sam C:\Windows\System32\Config\Sam
COPY _Registry_machine_security C:\Windows\System32\Config\Security
COPY _Registry_user_.default C:\Windows\System32\Config\Default

Type the command exit to close the Recovery Console and restart the PC.
