I recently upgraded my CPU to a and ryzen 7 3700x (which was said to be compatible with my Mobo and ram
Mobo:msi b450 pro-m2
Ram: Corsair vengeance lpx ddr4.
After installing, the monitor wasn't receiving signal. I figured the bios has to be reset/updated, so I put in the old processor, but the screen is having the same issue as the new CPU. I cannot get it to work the same way before I installed the new product ☹
