windows xp service pack i

[patti w.]

i have windows xp on my lap top. I downloaded the windows
xp service pack 1. Now my computer boots on and the
immediately shuts down then boots on again and shuts
down. This continues until I shut it off. I have tried
to reboot in safe mode, safe mode with commands, last
configuration that worked, etc. What can I do other than
reconfigure my hard drive.

If you mean it boots and then shuts down after it gets to the desktop after
logging on, you need to make sure your antivirus is up to date and run a
virus scan. Also make sure your system is clear of any malware, download,
install and run Ad Aware:

If this is not the issue, when you post back, please give a more precise
description of the issue, any error messages that might occurs and exactly
where in the boot process it shuts down.
