Ryzen 5 4500 no display

Good day,

I bought an MSI B450M-A Pro MAX to use as a motherboard for a desktop PC. But when I installed the intended processor (purchased new) (AMD Ryzen 5 4500) and started the system, there was no display on any of the 5 display options of the Sapphire NITRO+ RX 570 / on several monitors. I then set out to fix this problem. To test the various components of the system, I purchased an AMD Ryzen 5 2400G. After installing the processor and starting the system, there was a signal on the monitor and I was able to install the operating system of my choice (Windows 10 64-bit). The packaging/box of my B450M-A Pro MAX states that this motherboard should be compatible with the Ryzen 5000 series right out of the box. To be sure, I used MSI's M-Flash function to deploy the latest version of the BIOS/UEFI onto my B450M-A Pro MAX. But even after the successful BIOS/UEFI update to version 3J0 / more specifically 7C52v3J, there was no screen output on the AMD Ryzen 5 4500. On the AMD Ryzen 5 2400G, however, there was still successful output to the monitors. (I checked this several times). This confirms that the BIOS/UEFI update has completed successfully and the BIOS/UEFI has not been corrupted/fragmented. After this, in an attempt to fix the problem, I installed/updated missing/or old drivers on my Windows 10 64-bit using the MSI Driver Utility. After the succesfull installation, there was still no output on the Ryzen 5 4500 whereas there was an output on the Ryzen 5 2400G. The external graphics card has already been tested several times and works. I have already contacted the Support of MSI, the support confirmed that my processor should be compatible with my Motherboard.

Could you help me with this problem?

I look forward to your reply.

I had a similar problem with an Intel CPU and a graphics card. The only way that the box would boot was after the CMOS was cleared by a jumper on the MoBo. Consult your MoBo manual for the details on how to clear the CMOS.
