COM+Setup Error on re-installing Win XP

Actually this has been a big problem for me on these days. Few days ago, my computer which is at my office, was malfunctioned. It can't boot with windows.Then I tried to reinstall the Windows XP. Since at that time I am getting an error message like below image.

COM+ Setup Error Sub-component COM+ raised exception while processing the OC_COMPLETE_INSTALLATION setup message.
Error Code = 0x80040206
An unexpected internal error was detected
The COM+ event classes could not be registered.
I can do all the things before this step like formatting the hard disk etc.
But when I come to this step always I am getting an error message like this.
This error occurs again and again.I tried so many times to resolve this and I couldn't.
Can you help me regarding this??
