i have a lenovo y400 laptop. It has 2 i5 cores and im pretty sure 2 gpus that are nvidia GT 750m each. when i open the Nvidia Control panel, i don't see the 2nd graphics card i didn't have this problem before. But i may have fried this graphics card. Im not 100% sure if this is true but i need help so i can send it in to repair. I can still play games like Crisis 2 and bf3 fine. Should i send it in?
