Bought a new case last Thursday, moved all my equipment over. Worked fine until last night, started having cooling issues with my CPU (never had that before), and eventually the power supply just shut off. (no shutdown screen, etc). Turned it back on, after two seconds, shut back down, with a huge crackle, and an arc of electricity went down the back of the case.
I know the PSU is bad, I'm suspecting my CPU, motherboard, and video card, just because of the arc of electricity and apparent ferocity of the shut down.
