Assembled everything earlier today. Everything seemed fine except the cooler took a little more fidgeting than I liked to attach to the AM4 socket but I don't think it damaged the cpu (maybe it did, what do I know at this point). Turned everything on and all the fans lit up and turned on–including the mobo RGB and the cpu fan+radiator. Plugged it into my monitor and nothing shows up. Doesn't even give me the option to boot into BIOS. I
List anything you've done in attempt to diagnose or fix the problem. 've tried this with my boot drive plugged in and without it but I don't think that's the issue. Went back in and tried a few things, cleaned off the cpu thermal paste, wiped the surrounding area down a little bit, took out the ram and put it back in, did the same with the graphics card, and then tried to turn it on again and still nothing happened.
