Currently, nothing is plugged into it other than the Power Supply. I have even checked the CPU. To be honest, I think the Motherboard is dead. I didn't, because I, First, assumed it was working which it did. Second, It wasn't like I would get told more than I could notice. It worked just fine the whole while. One thing I noticed, though, Is that the Bios lagged the day it stopped working (The Arrow keys would not register as soon as I pressed them.) I have the Number of the seller. I might call him later to see what he has to say.
