Last October I built a computer and used an EVGA 500 W1 80+ white and my computer has started to restart occasionally, but only when I've been playing some slightly more demanding games for a little while, and I have checked every other component and they are all working properly, with the exception of my PSU. The fan never spins, even on boot or under heavy load, and I was wondering if there was any way to fully confirm if it is defective, or if something came loose in the PSU itself.
