Well, I got the system running with the 250W PSU, works fine. Ran a could of games, to see if it would handle a bit of stress, worked great. I don't know why, but I to the PSU out, and was going to switch to a different PSU, but I decided I would just give it another try, and with it out off the case, it ran fine, popped the PSU back in, worked great. I have successfully reformatted the computer, installed a few benchmarking wares, and a game or two.
