when your computer is updating do not turn off or shut down your computer this will be the reason for your windows operating system crash. just let the windows update to finish. this this type of error you will need to contact your computer manufacturer or try re-installing your windows XP. If you wish to reformat your computer make sure to back up all your files first.

you have to get an windows 7 os installer and first boot it to your dell and then try to access the repair option.

sounds like the driver you updated is causing it to shut down.try and start in safe mode and see if you can sort it from there.

On the windows boot screen you should be getting choices for safe mode, safe mode with networking, etc ...

Select "Disable automatic restart on system failure'

And let me know what error message(s) you have ... write it all down

Recovery SettingsOne of the things that is quite different about Windows XP compared to Windows 9x (9x is shorthand for Windows 95, Windows 98, and Windows Me in all their various versions), is that one can control how it responds to certain critical errors—those that cause the infamous Blue Screen of Death (BSOD). In Windows XP, the default setting is for the computer to reboot automatically when a fatal error occurs. If that fatal error only occurs when you're shutting down, the system reboots automatically.
If you haven't changed any of the system failure settings, you should be able to see the error by looking in the Event Log. But a better long-term solution is to turn off the automatic reboot so you can actually see the error when it happens—chances are it will tell you enough about itself to let you troubleshoot further. To change the recovery settings to disable automatic rebooting:
1.
Right-click My Computer, and then click Properties.
2.
Click the Advanced tab.
3.
Under Startup and Recovery, click Settings to open the Startup and Recovery dialog box.
4.
Clear the Automatically restart check box, and click OK the necessary number of times.
5.
Restart your computer for the settings to take effect.
Now when you go to shut down and a fatal error occurs, you'll at least see it and it won't cause an automatic reboot. You still have to sort out what's causing the problem, but that gets us to the next section quite nicely.

Go to emachines.com and see if there is a firmware update for your computer BIOS. Some thermostat errors are cause by a BIOS fault that can be corrected with a firmware upgrade.

Probably the only solution is to reinstall all the programs (starting with the Operating System).

If your unit came with a Disk, insert this before turning on and then follow the instructions after you have turned it back on.

Good luck.

you was probably installing updates in the background and youve interrupted install and shutdown improperly (reason)
turn on pc and press f 8. if youve never done this before;as soon as you see anything at startup keep pressing f 8 youll still get to the place you want to be.select start up using last known good configuration.
