windows hanging problem

[manni_n]

from sometime my system is getting hanged after half or one of browsing and continously after that. its not like the hanging due to non respondence of any program.. its just that suddenly windows gets jam, and no control works not even cntrl+Alt+Del. this problem is coming specially after i have installed new modem in my system. i think this might be the reason. i have no idea what to do. please help. thanks
