On motherboard. Please, make sure all fans are connected into motherboard.Some fans can't plug in into the board at all. So, you can ignore those fans.When you go to Bios to check thermal condition, if a fan is not plug in, you can see 0 degree. 0 degree dosen't cause the shutdown problem. (That's why you can ignore)Then check which fans are causing problem, first. (If you did and found the problem, go next.)Replace fans AND clean those dust!If the problem remains, then replace its case to steel one. Well, usually a lifetime of CPU fan is pretty longer than others.Just in case, one more thing, if the thermal condition is OK, then the shutdown problem is caused by something ales!

Below are some useful tips for making your PC's performance better.Please follow the below steps and fix your problem.
Eliminate Viruses and Spyware 1 . Run your antivirus program. There may be something slowing your computer that you can remove. It is a good idea to run your antivirus program every week.
2 . Remove spyware. Run a good spyware tool at least twice a month.
3 . Use a pop-up blocker, if you have one. Check your antivirus program.
Dispose of the Extras 1 . Delete your document files for anything you no longer need. Saved pictures, audio and video files in particular can slow your computer.
2 . Remove unwanted programs from the Control Panel area. Old toolbars or games the kids downloaded off the Internet are a good place to start.Look for software you no longer use, such as the old printer you threw out last year.
3 . Clean out your email. Old messages are a constant drain on your computer's resources. Go through every folder, deleting everything you do not need. Leave no mail! Finish by emptying the Deleted Items folder.
4 . Turn off unnecessary programs. Check your task bar for icons that show running programs. Disable anything you are not currently using.
Run Maintenance 1 . Run the Disk Cleanup tool located in your Control Panel. (Windows only. For other operating systems, please check the Resources section below.)This will remove temporary files, cookies and unnecessary components to speed up your computer.
2 . Defragment your computer. Defragging takes some time, but will speed your computer significantly. You can find the tool in your Control Panel.Run it monthly.

Hope the above information will be helpful to you. Thanks for using Fixya.

The Green LED light flashing indicates a bad Power Supply. Weak voltage power rail.

Troubleshooting Power Supply Issues HP Pavilion A520n,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph06788&tmp_task=solveCategory&lc=en&dlc=en&cc=us&site=null&lang=en&key=null&product=404643#N207

Click on > Power Supply light is on or flashes

"If the LED is still flashing (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced."


Cause?
The leading cause is the computer is dirty inside, to include the Power Supply
The next cause is that Electrolytic Capacitors have failed inside the Power Supply.

Solution is to replace the Power Supply.

The Power Supply used is the ATX form factor. The type of Power Supply used in over 80 percent of PC computers out there, and very readily available.

Size of the power supply case is approximately 6 inches Wide, 5-1/2 inches long (5.5), and 3-1/2 inches Tall. (3.5)

It is a 250, or 300 Watt generic unit, probably made by Bestec, Delta, or HiPro.

Scroll down to see the illustration and photo of the motherboard.

Power cables needed are;

A) 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

{ ATX power supply's today come with a 20 + 4-pin ATX main power cable.
The power cable can be used as a 20-pin, or a 24-pin.

Add the 4-pin connector to make it a 24-pin, or do not use it, and have a 20-pin }


B) Enough standard 4-pin Peripheral power cables for the IDE (PATA) harddive, {1}, and the optical drive/s.

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Today's power supply's come with either at least 4, or 6 of these power cables.

C) One Floppy Drive power cable.
Won't be used for a Floppy Disk Drive on your computer. It's power for the Memory Card Reader.

All of the above power cables are typical when purchasing an ATX power supply today.
Need guidance in choosing a Power Supply, please state in a Comment.

HI!
You can get it from the link below...

http://www.usedlaptops.com/

unplug the power cable, and remove the bettery from the mother board, and the ram 2, wait for 5 minutes then try again...hope it will help

ebay.com ;)
or you can try compusa.com
if that doesnt work just call 1-800-711-2884 HP tech support number and ask them ;)

hello, I recommend running a computer drive defragment.

also run a spyware/malware check. your computer may be infected.

Go to crucial.com and have them analyze your computer. They will tell you you can use 2gb, no matter what HP says, and it does work. I just went through the same thing. Saved me from buying a new computer because 1gb wasn't cutting it and I originally thought that was the max for a a520n. Not true. I do suggest going to HP and getting the Bios update from 2005 if you haven't already done that. My a250n runs great with 2gb ram, replacement 500 watt power supply, GeForce 6600gt GPU, and Audigy SE sound card. With optimized paging file and routine disk cleanup this thing still runs well enough to have a few years left in the old girl untill every new program requires dual or quad core 64bit technology and Windows 7 or above.

open the iTunes player and in the HELP tab you will find RUN DIAGNOSTICS check only the CD/DVD drive tests and push NEXT button before that insert an recorded audio CD in your optical drive if you have problems with your optical drive , the run test will tell you.

Well I have found all the drivers, here for you.
