HI I am reasonably sure this is a PSU fail. My Seasonic S12 power unit is about two years old, and runs a 3.2GHZ Q6600 based system with a OC"d 8800GTS 512MB. Recently been in storage for a few weeks since we thought we had to sell it, I took it out today, never being took away from room temperature or subject to any shocks I was suprised when NOTHING happened. I changed the power leads for the one in the tft which obviously worked and still nothing, nothing in the sense of the psu did not make a noise, the fan didnt spin, and the motherboard and NO lights on at all as if no power was getting through. Now the psu is quite dusty inside and I am wary of opening it up, but I have no warranty on it so could it be the dust or is it better to just buy a brand new one? I've under £100 and I'd like something modular but will take normal for the reliability and brand name. Really stumped as to how it has died on me while doing nothing... sods law eh?
