You can purchase a power supply from any computer store *********** board supports both standard IDE and Serial ATA connections, so you want a power supply that does SATA power as well. Unplug the power cord from the back of the computer. remove the cover from the case and verify that there is no green LED on the board that is lit up (if there is, there is still power on the board). unplug all connections from the current power supply, including all drive power and the large 24pin plug (actually a 4 pin plug that is combined with a 20 pin plug) on the board, then unplug the 4 pin plug near the processor. careful that the 24 pin plug and the additional 4 pin plug near the processor have latches on the side. Remove the 4 screws that hold the power supply in and remove the power supply, install new supply and reinstall the 4 screws. first plug in the 4 pin plug that connects with the 20 pin, the 4 pin plug has no latch, it is held in place by the 20 pin plug. then plug in the 20 pin plug and the 4 pin next to the processor. then plug in the drive power to all of the drives. Install the power plug at the back of the system and you should see a green LED on the board when you insert the power. replace the cover and power the system up.

Case fan not working sr5110nx


Some fans will not engage if the case is open, others need to be activated in bios (set temp). Also check if the wires are reversed. Some have a diode that only works with current in one direction. Very few use an ac current.

Green power light doesn't turn on but the yellow light goes on


In your added problem along with more information now, you have witnessed what I have previously stated;

http://www.fixya.com/support/t11034057-compaq_presario_sr5110nx_will_not_start

Bad Power Supply.
Weak voltage power rail.
Not enough power to turn the Processor on.

1) IF, all of the LED lights were on at once, they would use less than 1 Watt of power.

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

3) A typical processor can use from 51 to 125 Watts of power. Just depends on what Processor it is.

(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short )

The Processor in a Compaq Presario SR5110NX Desktop PC is an

Depending on what Core it is based on, (ClawHammer, Newcastle, Winchester, Venice, Manchester, etc), it can use up to 67 Watts, or 89 Watts.

No Processor operating, No computer.
Replace the Power Supply.

{ Also clean out the inside of the computer with a can of compressed air for computers, on a regular basis as needed. It may be every two weeks, if the situation calls for it.
Remember to follow Anti-Static Precautions, BEFORE reaching inside the computer.

N-E-V-E-R use a vacuum cleaner to clean a computer.
A vacuum cleaner produces Static electricity.

{Hold the plastic wand device sideways, over your hair with the vacuum turned on. Your hair will stand up from the Static.
Have seen many a so-called computer tech fry a unit using a vacuum }
