The power supply in my family's Dell Vostro 200 stopped working, so we planned on replacing it. I opened up another one of our old desktops and found a 300 watt PSU. The PSU that was originally in the Vostro 200 was also 300 watts, so this was perfect. I placed it into the computer and plugged in everything. The green light on the back of the power supply turns on, and there is an orange light on the motherboard. I go to boot the computer, and it doesn't turn on. Am I missing something that I need to do?
UPDATE: I unplugged the computer, and held the power button down for 15 seconds. The button is now blue, but the computer still isn't turning on.
