Find a means to that power connector and also rerelocate it and reset it earlier into location firmly. If there"s a method to affix it to the motherboard there"s always a way to disconnect it from the MOBO.but from whats going on i would certainly definetly assume a PSU problem.See more: Netflix Error Code Nw 4 7 Netflix Error Nw, How To Fix Netflix Error Nw#8dc3dc3ArachibutyrophobiaMembers32,510 postsOFFLINEGender:MaleLocation:Sierra Foothills of Northern Ca.Local time:11:27 PMIf you have actually a DC voltmeter take among the totally free molex connectors and read the voltage tbelow, if tright here is no power it might be the PSU.
