Computer crashing giving out an error BCcode 0x1000007e

I'm not sure if I'm putting it in the right forum.
But anyways, here's my problem.

I guess it's an ati VGA driver problem.
I've tried to reinstall all the drivers again,
but unfortunately the problem hasn't been solved.

I've attached the minidump files and a simple image of bluescreen lists.

Thanks alot.

Ps. It mostly, almost only happens while playing games, which raises the CPU (core) temps up to 75~80 C, if this could be one of the reasons, which looks unlikely as I use a laptop.
