G20AJ Recurring Malfunction With Certain Games

[The_Matrix_Man]

Hello, I've had a recurring problem with my ROG G20AJ desktop for quite a while now, and was hoping if any of you could think of a solution. The malfunction only occurs while playing certain games. To describe it, the screen turns one color, while the last sound bite that played before the malfunction loops for a few seconds, before going silent. After the malfunction, the computer doesn't shut off, and my only option is to force a shutdown. I've tried cleaning the dust out, updating drivers, re-installing the operating system, and I recently got the 180W power adapter after realizing that I only had the 230W adapter. But, the problem still persists. If any of you have an idea of what it might be, or need more information, please let me know.

I have a NVIDIA GeForce GTX 750, and speccy says it's at around 70C when the problem occurs.
