Hi Ranjit, welcome to the forums

Can you open up "Event Viewer" (search for it on the start menu) and look up some of the advanced details when Internet Explorer crashes. If you paste the crash details in here it may help pinpoint the problem.

This sounds like it could be unrelated to your network adaptor problem. Are you using the latest network card drivers?

Don't Forget to said to me Thanks if My Advice will help you.

Luckylaad, there is no need to install and run so many programs. The OP allready scanned the computer with his AV and with malwarebites.
Installing so many programs will most probably find nothing and bloat the system, making it worse.

As Ian said, it is most probably going to be related to the network card. And anyway, this thread is 1 month old, and seeing that there haven't been any replies in 1 month, what's the point in bringing it back up?
