Hi, buwish

Thanks for reply.

yes it hangs after 30-50 min.I dont think it hangs due to certain programs. specificly it hangs when i am connected to internet.
I am surfing throught wi-fi connection.
currently using mozilla 3.6. quick heal antivirus (total security 10.00 evaluation copy).

I searched about the problem on net found that it may due to processor or video drivers installed n soln for that is reinstall the proper video drivers.but it no use.

configuration of laptop is - Pentium Dual Core 2.2GHz,800FSB,45nm/3GB Ram/ 320GB HDD/DVD RW/ 14" HD LCD/ WIFI/ LAN/MODEM/ Bluetooth/ Web Cam/Card Reader/Finger Print Sensor/3USB+1HDMI ports.

So,plz assist me to get out of this problem.
