Driver_IRQL_not_less_or_equal, I don't know much about computers

Hi, I have used my laptop for almost 2 years. Just recently it get this BSOD error, I don't know how to resolve it. I've tried re-install my windows but it still occur. My laptop is Asus X42F. I am using windows 7 professional.

I also upload the minidump file here: #mce_temp_url#

I'd be very appreciate if anyone can help :((
 
If you have Bitdefender Total Security 2013 installed, this is what is causing the BSOD... Remove it and see if the BSOD stops
 
Usually in instances like this, especially if the user bought the software, is to completely uninstall (using the removal tool), and reinstall it. This should resolve any BSODs.
