I have an msi x570 tomahawk mobo and was using a 3600x cpu to get it all running. The 5900x arrived today and i fitted it.
I get a black screen with no post or bios onscreen, it will boot to windows after 3 attempts but i cant get into the bios at all it just stays black screen
Iv tried updsting the bios and resetting it, also renewed the 6800xt drivers too, no joy. Any ideas whats goin on?
Ps it worked fine with the 3600
