Today I went to finish rebuilding my computer and i am having a issue with my ryzen cpu Its been stored in the original box in the garage a large box i keeps my pc parts in. Now i did clean off the paste and reapplied it many times. The cpu won't stay in the cpu slot on the motherboard. Is it a faulty cpu or motherboard? I tried both my cooler master cpu cooler and the one that came with the cpu. I don't know what to do.
