My PSU is a PC Power & Cooling Silencer MKII, and I think it's dead - I checked with multiple power cords and multiple outlets, I could try hooking in another power supply but I can't seem to quite put my finger on it, and the really weird thing is that the system completely powered on two days ago and now I can't seem to get it to get any power going to it. I checked all the connections and everything is secure, the CPU cooler is secure, and everything is connected. The full specs are in the link in my sig. Is it the power supply, or is it something else?
