Power Supply. Weak voltage power rail.

Has enough power to light LED lights, maybe spin fans, (Or spin a few times, and stop), but not enough power to turn the Processor on.

1) ALL of the LED lights combined use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

Acer Aspire M1641-U1521A?
Intel Pentium Dual Core E2180 (2.0GHz)

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_Dual-Core_microprocessors#.22Allendale.22.2C_.22Conroe.22_.2865_nm.29

Can use up to 65 Watts. (TDP)

The Power Supply used is a 250 Watt unit. Acer isn't known to use high quality power supply's. It's a generic low quality Power Supply.

[ However in all fairness to Acer, if the inside of the computer, AND the inside of the Power Supply, isn't cleaned out on a regular basis as needed, this can cause Power Supply failure also.

Use a can of compressed air for computers, with the plastic 'straw' attached. Hold onto the can with one hand, use the other hand to hold onto the straw, shoot air through the ventilation holes of the Power Supply's case. (Computer unplugged from power)

Come around to the back of the computer, use the air to clean the Power Supply's fan blades, center hub, and surrounding cage. (Shroud)

When the cooling components for the Power Supply, (Fan and Heatsinks used inside), become clogged with dust, dirt, etc., the cooling capacity drops tremendously.

The Power Supply overheats.
Heat = Wasted Energy

The Power Supply strains to keep up with the call for power, but eventually cannot, and fails.
Components inside the Power Supply fail ]

Replace the Power Supply.
