http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c01050244#N232 Is the link to find your answer. And in case you get lost.....

FROM WHERE YOU HAVE TO BE MOORE DETAILED.

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.

you wont find one... and not sure why you need one.... if your changing the case then trail and error wont hurt anything

Hello Friend,

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 }

Click this product specifications review http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01050244&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&site=null&product=3436819&key=null
If you need SD slot try to purchase external USB type universal SD all in one slot.

Hope can help you.

clear all 3rd party startup items you dont need with msconfig.exe. Uninstall bellaliant and use microsoft security essentials as main antivirus software and defragment your hard drive.

You can replace power supply the higher wattage the better.

just download imgburn which is a free software to burn dvd's etc. Google "imgburn" and follow the appropriate links to download. Its easy to use by the way.
