Serious problem, blue screen of death

[Game-addict]

hi guys, I have a Toshiba Satellite laptop C660-1ME & in the last cpl of days this blue screen keeps showing at least 2 times daily, my laptop specs are
Core i5 2410M, nVidia 315M turbo cuda, 500Gb HHD, bluetooth, Atheros Wireless...etc
am runniNG win 7 Ultimate SP1 & using ESET Smart security 5.2 which I 've been using for along time & had no problems with it whatsoever !!
When I get the blue screen my system freezes then reboots again where it asks me to choose whether to boot windows in normal mode or safe mode so I choose the normal mode & my system goes back to work for a while then it crashes again... IDK what's the real problem !!
I managed to get the report of these multiple crashes & all of them say the same thing giving the same data:

Looks like it's related to networking. Have you installed any new network drivers recently? Try disabling any third party firewalls, and for kicks, try scanning with Malwarebytes.

I didn't install any new drivers, my windows firewall is off & the only firewall I have is the one provided by ESET, did a scan for malwares using Malwarebytes but nothing came out..
Just for the record am using IDM (Internet Download Manager) & Waterfox 16.0.1 which is a 64-bit firefox based browser, IDK if you're familiar with it
http://waterfoxproject.org/
been using this browser for a long time & never had any problem with it, the new firefox browser 17.0.1 got so many bugs & it crashes many times, this waterfox is much stable but when I open multiple tabs when playing facebook games my system crashes to this blue screen, IDK if it's something related to multiple tabs, the game, the browser or even my wireless driver!!! the next restart I encounter got me to use chrome to eliminate browser factor, so far nothing happening & am still playing FB games but will keep an eye on what's going on, tho some facebook pages don't load properly, even got some blank tabs that keep circling & never load!!!! :\
