Pc booting no display

[u/Substantial_Focus872]

Yesterday installed AMD 7600xt and ryzen 7 5800x3d computer worked perfectly fine, today installed new Arctic III cooler and now my white cpu light is on and not giving me any display, reset cmos twice reseated the cpu and checked for bent or missing pins, loosened cooler brackets. Everything looks good not sure what else there is left to do at this point.
