So I installed new 2x 8GB DDR3 ram for my PC and it started beeping, then I installed my old RAM again (2x 4GB DDR3) and it booted into bad colored low res windows. Now it does the same with my new RAM (it boots into windows, but screen is low res and bad colored). But it only boots to windows when i use GT 740. With my RX 570 4GB it doesn't even want to boot into windows. What should I do?
