Gopinath Annamalai......When you installed NT ....did you do it on a properly formatted HD ........AND did you get any available updates from Microsoft ?
I cannot believe people who are on line with out any anti virus software ...it only takes a few minutes and your pc could become infected .........You should immediately get some sort of anti virus software and see if your pc is infected ....
"But the system hangs like anything" exactly what do you mean it hangs ? I'm rubbing my crystal ball ....but I cant see a hanging computer. Please help me ......
You should also get some antispyware scanners as well ........Adware etc. can slow down your pc as well .
A decent free adware scanner is ........antispyware ( free ) .... http://www.microsoft.com/athome/security/spyware/software/default.mspx be sure and get all the updates for it as well .
Let us know how you make out
