Hi all. I moved out of a 14-year-old case (Gateway) and into an Ultra brand Gladiator mid-tower. I have an EVGA nForce 650i Ultra Motherboard, and a "Power Up" brand 450-Watt power supply. The setup worked fine in the old case, though Windows was freezing regularly after 15 minutes. I figured that was related to the hard-drive, since it wasn't tightly mounted, and I wasn't using enough cooling fans. So I got a new case and cannabalaized a fan from an old computer. The power outlet and cord are good, and I swapped out the power supply with a 230 watt unit, and pulled the switch from the old case, but neither powered on the computer. Nothing seems out of the ordinary with the switch on the case I bought. Did I buy a defective unit? Is there something I'm missing or should try again? Something else? Thanks for the help.
