I am in Australia using Windows XP SP2 and am having trouble booting my laptop. When turned on the laptop runs through the boot process but then sometimes gets to the login screen, sometimes just hangs and sometimes allows a user to logon.
The same problem also occurs when attempting to login in safe mode. Sometimes it allows the user to login but most of the time it hangs on or just before the login screen.
The problem occured after running a number of security updates on 13/10/2005. I have removed these updates but the problem still exists. The harddrive is only half full with 40gig free.
Please let me know if you have any ideas.

Thanks
Chris
