Re: I am not getting power to the fan in the fan...
I will be more than happy to assist you with this problem, This is a critical problem..That I would not take upon my own hands if i were in your shoes..Your best bet especially with a computer manufactored by HP, would unfortunately be call them..Get as much information as you can out of them, I can though provide you with power trace source software but it's critical and could cause major issues to your desktop. Also, If you do decide to contact HP with this critical question there number is 1-800-HP-INVENT. Now a question I have for you is do you have warranty on your HP Desktop product? If not, I would be more than happy to get with you over via phone, or via

Lets start at the ram always place the largest ram module closest the CPU central processing unit.
One bad lead can cause a computer to continue on a
cycle of restarting or to shutdown or fail to detect/ boot up a computer
WARNING: Before you start
troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php
Only work inside the computer case
when the power has been switched off and disconnected. Never open the power
Some of the below steps
recommend removing physical parts within the computer.
While in the computer it is
highly recommend that you be aware of ESD and its potential hazards
Remove the memory modules from their
slots. Take the
opportunity to clean the slots on the motherboards and the memory module
Use compressed air to blow dust away
and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner
if it touches any component it may create a short and cause damage to the
motherboard or other components. Do not use
solvent that may attract dust and never poke things like cotton buds in to

the issue try swapping the location of the memory.
If you have only one stick of

Mixing tin and gold can result in
corrosion that prevents proper contact.
Look for any sign of physical damage
to the memory module, memory slots or the motherboard.
Reseat the memory modules.
You should hear an audible click
when they are in place.
Do not use
too much force to reseat the memory module in to the slot this can cause damage
to the module, slot or motherboard.
The hardware that you are trying to
access is damaged or failing.
Test all power and data leads that attach to your hard drive IDE,SATA

computer needs power and data to travel through every working device and
continue its cycle and have an end so any faulty leads will end up with a

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.
You may need to check to see which "service pack" you are currently on.
See below requirements:
System Software — Windows XP & Vista
Windows Vista Business or Ultimate Edition
32-bit OS Installation Only
Windows XP Professional or Home Edition
With Windows XP Service Pack 2 or Service Pack 3
Windows Vista 64-bit (any version)
Windows XP Professional x64 Edition
Windows XP Media Center Edition
Windows 98, Me, 2000, NT, 95, 3.1, DOS
Windows Vista Home and Home Premium Edition
Although Windows Vista Home and Home Premium Edition have not
been tested or qualified by Digidesign, there are currently no known
issues with Vista Home and Home Premium 32-bit operating systems and
Pro Tools M-Powered 7.4 compared to the supported Windows Vista
Business or Ultimate Edition operating systems.
Windows Vista SP1
There are currently no known issues with Service Pack 1 for Windows
Vista based on our initial limited testing and customer feedback.
Although full qualification with all Digidesign products has not been
completed, we do not recommend against updating to SP1, given the number of important overall system fixes in SP1. We do
recommend that you backup your system and create a restore point before
updating to SP1, should you encounter any problems after installing the
Believe it or not, it's due to a weak power supply. More specifically, weak voltage rail/s caused by failing Electrolytic Capacitors.
A bad computer power supply is about 70% of computer failure.
ALL the light use less than 1 Watt. EACH fan uses 2 to 3 Watts.
A processor uses 55 to 125 Watts. Depends on the make and model.
Since the power supply is weak, it doesn't have enough power to turn the processor on. No processor, nothing to find the Boot record on the harddrive. Nothing to get the Operating System going. (Example: Windows XP)
No computer running, there is no signal to the monitor. Just enough power to light lights, and spin fans.
First, check your monitor, Is the power light on and amber?
If not , monitor is dead.
If monitor light is amber, Check the power supply fans and cpu fan. See if they are operating ok.
If monitor is coming on, fans are working, I would Pull out the adapter boards that are installed, then power on the unit. If the unit displays video, then reinstall adapters back in one at a time.
Make sure you power down when ever you remove/install anything in the PC.
different beeping patterns are codes which indicate what part of the hardware has failed (ram, video card, cpu, ect). the fan failure would not cause beeps, and would not cause the cpu to fail unless already in windows. if you could find out the manufacturer of your motherboard you could check with them about what the paticular pattern of beeps which you are getting mean.
