The computer is a Dell Vostro 220 Slim Tower (regular tower.) When the power button is pressed, the computer exhibits the following behavior:
- No lights turn on
- No noise is heard
- No fans turn at all
- Monitor says "No Signal Connected"
The computer was on an APC battery backup, so this was not caused by an electrical anomaly as far as I know.
What I tried:
- Replaced power supply
- Replaced power cord
- Plugged into completely different outlet (w/o battery backup)
None of these things changed the situation.
Is it the motherboard? Or could it be the RAM/CPU?
