Any abnormal thermal issue? Like bad sensor? Bulged caps or bad caps?

The temperature of the cpu and gpu seem alright I have a suspicion that I may have a problem with my graphics card

Only during heavy load? If it's not temps, it's likely an electrical issue. Sounds like a problem with either the AC adapter or the main board, more specifically with the GPU if that ends up being the case.
