I'm upgrading my system for an AMD Ryzen 5 3600 to an AMD Ryzen 7 3800XT. Installed the Ryzen 7 but the MB will not POST. My MB is an MSI B450 Gaming Plus Max and I have an NVIDIA GeForce RTX 2060. Noted that the processor box stated that Discrete Graphics Card Required. Is there any way to make the processor work without the purchase of a new graphics card?
