BSOD in Toshiba Laptop with AMD Radeon Graphics

Hello,

while playing games I have noticed my brother's laptop screen freezes, showing physical dumping reports.
it happened before but not as much as its happening today.

I cannot run my laptop in normal window mode. It only starts in "safe mode".
The message appears is as:

I've collected all the necessary information as instructed in this forum. I dont have much technical knowledge. Please help me solve my problem.

Well, I used to play a lot games all together. Today I was trying Splinter Cell Blacklist. Unfortunately I could not even play for 5 mins and the bad thing just happened!
By the way I am using Windows 7 64 bit Home+AMD Radeon HD 7670M+6GB RAM+500GB HDD. In my laptop there are many installed games like Assassin's Creed III, Far Cry III, Call of Duty etc. Also I am using Clone Drive and software like AutoCAD 2013 (which I just uninstalled), MAtLAB etc.
Does it have anything to do with these? Or do I need to repair my OS?
I am really confused?
