Sometimes when i start up my computer i will hear like a click sound coming from the psu and then my computer will freeze and i will have to restart it. Is it for sure my psu or could it be something else. By the way this is a cheapy psu that came with my case and i have alot of lights hooked up to it. Could i be overloading it? Also i was thinking about going with a Hiper 530 watt psu it fits my price and i really like the modular cables.
