Air compressor will not start

An electric air compressor motor may start up fine on an empty tank but not when the tank has air in it. Additional torque and power is required to start when not empty. The electric wires may be too small or their length too long and represent electric resistance in the circuit. Larger gage wire will have less resistance and provide more power at motor start up under load.
A motor uses 6 times the amps when starting, a normall size and length wire is capable to deliver this power momentarily. The problem is when the wire is lengthened without using a larger gage wire. Resistance consumes power and the wire resistance will consume power causing a voltage drop to the motor. A motor, as most electric loads needs plus or minus 10% of its rated voltage to operate. What I'm saying is that a larger gage wire must be used, 1 gauge size to 25 feet, 2 gage sizes to 50 feet, or more size larger when using extension chords depending on length. I keep some romex of heavy gage with chord ends on it to use as temporaty long extension chord for compressor or welder use.

The power button light on my dell pc is

You can install the power supply from another computer provided the wattage is equal to or greater than the original one.
The only problem you may have is the physical size og the power supply. The desktop computer power supply is usually larger in size to the smaller compact computers. You won't know until you remove the power supplies from both computers. You can also purchase power supplies from computer repair shops or on the Internet.

What is the correct amps for the 12 volt transformer

the current measured in ampere which depends upon the resistance . V/R=I{ohm's law} . as resistance is low , current becomes high . power supply gives that much current which circuit takes no fixed current transformer gives whatever current mentioned on the transformer .i.e., maximum current capacity of that transformer .

You don't really need to replace the power supply, you can repair it by replacing the bad capacitors. I've done it to 2 Nec monitors and it works. However I do not believe its you power supply because you are getting the power on light.
