I cannot get past "cpu" stage when booting up after replacing the 1950x with the new 2990x threadripper2. Granted I do not have the graphics card plugged in but I know from experience that as soon as it gets to 'cpu' I get an immediate shutdown and I need to look no further. I can also put back my 1950x and get back up and running without issue. Tired of doing this and hoping my new TR2 is not d.o.a. Any ideas? Here's the rest of system: I believe I'm fully compatible
