BSOD atikmdag.sys atikmpag.sys

So over the past few months, my computer has BSOD every so often, mainly when I am running something graphically heavy. I've tried looking through as to whats causing the problem... I believe it is atikmdag.sys that is causing the problem, but all the fixes i've applied, nothing has fixed it. I currently am running an older video driver and the problem happens less frequent, but still happens.

It would be helpful if someone can shed some light on my problem.
I have attached the DM log.

Edit: Since i'm pretty sure people are going to suggest updating to latest graphics driver, I took the initiative to DDU and install 14.12 (latest driver). Will Post if BSOD again. But still would appreciate any insight from the DM logs if there are anything else.

Edit 2: Still BSODs with latest video driver. Memtest86 shows no problems with passes. looked through my BSOD dumps and saw hal.dll and ntoskrnl.exe are causing some of the BSODs. Any thing else I should try?

It certainly appears as if the video card or its driver are shot. However, I find that analysing .dmp files on tampered counterfeit installations such as yours is very unreliable. I suggest starting with a clean installation of a genuine Windows 7 first, then taking it from there.
