I have a issue with my desktop where when i press power button fans spin for a few seconds lights turn on then it stops and tries turn on again and it goes in a cycle. when i unplug the cpu 8 pin the fans run properly and everything other turns on. Sometimes when i cleaned it with a vaccum to remove dust it would turn on and run properly for days as long as i dont turn it off. when i turn it off it again stops working and i have to blow air at the motherboard again. sometimes when i blow air on motherboard it starts the 1st time other times it takes hours.I have ordered a cpu and a motherboard but i was wondering could it be the psu its a corsair rm750x which i got a brand new through rma a month back.If it could be the psu won't it stop working while in this case it runs properly for days?
