Question about Dell Optiplex 755 Minitower Desktop Computer
Only light otherwise is the green led on the network card. No fans, optical drive or anything else powers up.
Sounds like you only have power going to your motherboard.
The power supply might be bad on it, that or maybe the power cord is going bad and is only letting a small amount go through. I don't see why there should be a problem if you have even a little bit of power going though.

A solid green light means the computer is operating normally.
A solid yellow:- the power is operating fine but your computer not processing data. This could mean there is a problem with the CPU or another component on the motherboard.
A blinking yellow light: power supply is receiving power from the wall, but not functioning properly. This generally means the power supply itself is bad and should be tested or replaced.
A blinking green light means the computer is in standby mode
