I am using a desktop computer with the below configuration
MS Windows XP Home SP3
Intel Core2 Duo,CPU [email protected],3.0GB RAM,Intel G45/G43 Express CHIPSET.
Since of late on start up the windows starts normally, but after the desktop icons show, the

computer hangs and is non responsive. The mouse pointer shows in the center with the

(WORKING in background) hour glass which is steady not tumbling. Cannot open any files or

programmes.The items that appear on the bottom right of the task bar also does not show up.

The antivirus soft ware also does not start up. click on the 'start' button has no response.

Ctrl+Alt+Del no response. Also the time display does not change with time. On Using the

reset button which restarts the computer also produces the same situation after the computer

restarts.  There is nothing that can be done for a minimum of 15 minutes.

What happens when you try to start in safe mode?truenorthI had a problem recently that sounds like yours. A ROOTKIT had infected my system, and was eating up the cpu power causing hard lagg. The solution I found, after trying a dozen rootkit removal programs, some found it some didnt, but none would get rid of it until I finally used mcafee rootkit removerhttp://www.mcafee.com/us/downloads/free-tools/index.aspx
I hope that help's, if not then:
1.Are you able to do anything at all once your in windows or does it freeze permanantly.
2.Do you have access to a second pc that you could put problem HD in to access the files.
