I believe it is the problem. I recommend you uninstall that, and use Microsoft Security Essentials... flawless with Windows 7.

i uninstalled bitdefender and the laptop seems to be working fine!i havent had any BSOD for the 20 odd minutes since uninstalling.they were really becoming frequent.thanks my bro :) .tell me,is microsoft security essentials as reliable as som of the other security packages out there?

It is the BEST, especially with W7. I will NEVER pay for security again.
