So I recently installed a new cpu into my pc, I installed a ryzen 7 2700x from a ryzen 5 2400g. After installing the ryzen 7 the first time I got nothing, no display or anything of the sort. I just thought oh well and put the ryzen 5 just so i could work with it later. So another few days come and i put the ryzen 7 in again and i have 0 display again. I reset the CMOS and reseated it multiple times. I then put the ryzen 5 in and I got nothing with that either. I checked my motherboard manufacturers website and it is supported. I've gone as far to buy a new PSU and I've still got nothing. Today I turned it on with the ryzen 7 in and I got it to boot and install windows, and it ran fine I started it with 4 gigs of ram as a start then put in 16 after I restarted. I now have no power to the back ports and my display just won't work. Please help.
