So I just finished dusting and did some rewiring on my PC. Went to test it, and the power cord was lose when plugging it in to the PSU. It was so picky as to where it would wprk and the PC turned on or nor, and I tested another cord with the same issue. I've never had an issue with this until now. Not sure what caused it and not sure where to go. Any thoughts? Thanks!

PSU is a EVGA G3 650W PSU.
