Hi,
all your dump files are the same bugcheck 3B and can either mean you have some corrupt data and/or old drivers or you have a hardware fault possibly RAM.
One was apparent straight away in that your missing a service pack. Please download and install service pack 1:

If you have issues installing the update the you might need the update readiness tool:

Apart from the GPU driver you also have some pretty old drivers although with lappies I'm sure your aware that it's the manufacturer who supply the updates. Checking the support page I don't think there's much to update:

If the issue persists after installing the above check Windows hasn't got corrupt by running the system file scanner:
Find command prompt in the start menu, right click on it and run as admin. Type:
sfc /scannow
Press enter and await results

It might also be worth testing your RAM too. Download and run Memtest86:

If possible run overnight or for 12 hours.
