recently my psu has been very loud and rattles a lot, now it will sometimes not turn on from cold for up to 4 hours and the time is not in sync witch makes me think it cant charge the cmos it dose eventually turn on i don't think it can be mobo because i am not seeing anything strange going on i have tested ram and cpu all seems fine the psu is evga 650w bronze 80 plus (also at high rpm the noise goes away and also sometimes when i give it a little tap with my hand )
