hi all first of all sorry if this is the wrong place for some time now when i first turn my pc on there is a sounds like a car engine on tick over it sounds as if it’s coming from the psu after the pc as been on for around 10-20 minutes it stops and sounds normal again i am planning on buying a new pc in September time and if it’s the psu do you think it will last to as i don’t want to spent money on new bits for it if it’s being replaced thanks
