I got a new cpu (ryzen 9 3900x) and a new case nzxt h710 and since i’ve built it, it turns on fine all fans working including new kraken 3 fan aio and the motherboard (msi b350 gaming plus) light and gpu light turn on (1060) my keyboard lights up my microphone lights up but my mouse seems to not come on, I have 2 monitors which I have switched the cables around on both switching from hdmi to display port and still says no signal on both, I have tried putting hdmi in motherboard slots instead of gpu but no fix, I have never had this problem before I took the ram out and placed it back in still using channels 2 and 4 for dual channel (maybe I should try 1 and 3?) I have took out my gpu and even put it in the second slot still no fix, I still use my hard drive that already has windows and all my storage I am all out of ideas and mentally drained im going to sleep, Im back at it tomorrow can anyone please help me?

That motherboard only supports the 3900X if you have the latest BETA BIOS version 7A34vMHR.

Reinstall the old CPU and flash the BIOS then install the 3900X.

Thank you I appreciate it I will definitely try it out, I know it definitely supports it but its bios is outdated for sure, i’ll download it on to a usb then boot from flash drive thank you.
