Need Help. BSOD Atikmpag.sys random crashes and black screens

Hello there, new to this forum and pretty much anything technical.
I recently changed my motherboard and processor to a Gigabyte GA-Z77-DS3H and an i5 2500k Graphics card is a Radeon HD6950. Before i never experienced this problem but i started to get this blue screen with the error coming from atikmpag.sys.

I assumed i needed a fresh windows install and this still didn't fix this problem. Did a bit of research about it and tried a few things like updating my motherboard bios and not installing catalyst control centre and still nothing. This error occurs randomly, sometimes at boot sometimes during gameplay, sometimes i can go hours without it occuring.

I'm not very tech savvy but i can provide details if needed would maybe just need a bit of guidance on what i need to do.

Posting this if it can be of any help at all with solving this irritating problem
