BSOD while playing 720p video.

Hi, I just recently re installed my OS(Win7 Home Premium x64) and today I was playing a 1280x720p MP4 with Media Player Classic 64x and K lite codec pack(64 bit version) installed. I had paused the video and when I went to resume it the audio was gone, so I closed the player and opened the video again and skipped to where I had left of. SO suddenly my screen turns black for a few seconds and the player stopped responding followed by the BSOD.

Note:
I had my CPU locked to 1.4GHz which is the default frequency anyways and its default voltage. Depending on the workload the CPU frequency jumps up and down and I didn't want that.
I just thought I should include this :/

Thanks.

Please update your graphic card drivers

I already did.
I downloaded the drivers for the HD 6520G from the Toshiba website and it says it's up to date. And actually they don't seem to have the model I have listed.

They do have the Satellite L750D drivers and one that has the same CPU and GPU as mine but they have different part numbers and other Model names L750D-ST4N01 for example. But mine is a L750D-037. Back then a friend told me that I could still use those drivers though but I am no longer sure.

I still do have access to the original drivers that the laptop came with though. Should I try those again?

You could try installing the manufacturers drivers.. They work the best and see if the problem persists.
