Hi, i have had this system for around a year which was built by myself it has been running perfect for the last year up until this summer and what happens is on hot days the pc refuses to turn on no post no fans spinning nothing. So i re seated everything and still nothing but it seems to work just fine on cold days? The only way i can force it to turn on is flick the switch on the wall plug and the psu. My psu is a Corsair ax750 which i really doubt could have failed within a year? Plus it seems to work fine sometimes and normal operation is perfect. Plz Help!
