I need some help, I recently bought a Ryzen 7 3700x to replace my Ryzen 5 2600. I have an ROG Crosshair VIII Hero motherboard, NVIDIA GTX 1080 Graphics Card, 750 Watt PSU, and 16 GB of Corsair 3200 Mhz ram. When I originally tried the CPU, it didn't boot. I then returned it and got another one thinking it was a dead CPU, but to my surprise, still no boot. I tried a different motherboard, and different ram in the new motherboard, still no boot. It was still booting with the graphics card so I never changed that. I updated the BIOS to the newest version, and cleared the CMOS every way possible. I returned the 3700x but I still really wanna upgrade. Any suggestions as to why it wasn't working or what I should do?
