i did not have a wrist strap, but I always ground myself on the case prior touching any components when the case is open [touch METAL inside the case, such as around the PSU or on the bottom of the case]. It is still possible I shorted the motherboard with static electricity, I suppose.

If thats the case, should I be worried about other components? I can test my Video card on my old motherboard that still works, but I'm worried about the CPU and RAM, I don't WANT to put faulty parts into a new motherboard and risk anything. quote author=selfpittypiggy link=topic=100417.msg686312#msg686312 date=1267780838]
