Display adapters causing problems

I am looking to clean up my Computer a little bit as some of the java apps and games i enjoy are starting to have problems with the display adapters i have installed on my computer. I currently have both the AMD Radeon HD 6620G as well as the AMD Radeon HD 7400M Series listed under display adapters in my device manager and i am not sure which one is causing problems so i am going to simply remove them both completely and start fresh by installing a single display adapter. I created this post to see if anyone on here knew either what display adapter i should install that would be best for my computer or if anyone knows how i can go about figuring this out for myself.
