Boot to your XP reinstall disk and do a repair or reinstall.

If I re-install XP using boot from CD and not formatting the HDD, then do I have to install all the softwares I have now?

You can do a reinstall without the format, but that is a ticking timebomb, Applications might work for a while, But it is not recommended as a viable solution. 

I would suggest selcting a diagnostic or selective startup using the MSCONFIG utility. (Start/ Run/ MSCONFIG) and test how it logs in, it most likely is a program on startup, I've seen some a few programs causing similar issues. If you do decide on a repair install, I wish you luck. 

Hi,

Instead of re-installing I tried to do System Restore. But I am facing these errors while doing System Restore.

1. When I am trying to do system system restore to an earlier date, I am seeing following message. If I click OK, next screen comes but 'next' button is not working.

"Changes made to drive(s) H: after this point cannot be reversed because the drive was either excluded from System Restore monitoring, or was turned off or removed."

H is my external HDD.

2. And when I am trying to create a restore point, then system is asking me to restart the PC and try again. I restart the PC but same error comes.

Pls help. I have lots of softwares installed in my laptop.

Thanks.
