Question about HP Pavilion a320n PC Desktop
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. 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 new hardware If any new HARDWARE has been recently added to the computer, remove that hardware to make sure it is not the cause of your issue. If after removing the new hardware your computer works it's likely the computer is either not compatible with the new hardware or a system setting needs to be changed to work with the new hardware device. Remove any disks or USB devices Remove any disks, CD's, DVD's that are in the computer and if any USB devices (Ipods, drives, phones, etc) are connected disconnect all of them as well. Reboot the computer and see if anything changes. Disconnect external devices. Remove everything from the back of the computer except the power cable. Turn on the computer and see if it beeps normally. If the computer has never beeped keep the monitor or display connected to see if any change occurs. Check all fans Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for theCPU) your computer could be overheating or detecting the fan failure causing the computer not to boot. Check all cables Verify that all the cables are properly connected at that there are no loose cables by firmly pressing in each cable. All disk drives should have a data cable and power cable connected to them. Your power supply should have at least one cable going to the motherboard. Many motherboards may also have additional cables connected to them to supply power to the fans. Disconnect all expansion cards If the above recommendations still have not resolved the irregular POST, disconnect the riser board (if applicable) and each of theexpansion cards. If this resolves the issue or allows the computer to POST connect one card at a time until you determine what card is causing the issue. Disconnect all drives If you were unable to determine by the beep code what is failing or do not have a beep code disconnect theIDE, SATA ,SCSI or other data cables from the CD-ROM ,Hard Drive and Floppy Drive from the Motherboard. If this resolves your irregular POST or generates error messages re-connect each device until you determine what device or cable is causing the issue. In some situations it can also be a loose cable connection that causes the issue. Remove the RAM If you continue to to receive the same problem with all the above hardware removed, disconnect the RAM from the Motherboard and turn on the computer. If the computer has a different beep code or if your computer was not beeping and is now beeping turn off your computer and try the below suggestions. Making sure to turn off the computer each time you're adding and removing the memory and then turning the computer back on to see if the suggestion resolves the issue. Re-insert the memory into the same slot. If you have more than one stick of memory remove all but one stick of memory, try rotating through each stick. Try one stick of memory in each slot. If you're able to get the computer to boot with one or more of the sticks of memory it's likely you're dealing with some bad memory. Try to identify what stick of memory is bad and replace it. If you're able to get memory to work in one slot but not another slot. You're motherboard is defective you can either workaround the issue by running the memory in a different slot or replace the motherboard. Power cycle the computer In some situations a computer may have power related issues often caused by either the power supply or the motherboard. To help determine if this is the cause of your issue try turning the computer on, off, and back on as fast as possible, making sure the computer power light goes on and off each time. In some situations you may be able to temporarily get the computer to boot. This should only be used as a temporary workaround if you're able to get this to work. Often this is good for users who may have not done a backup and need to get the computer up one more time to copy files before starting to replace hardware. Disconnect and reconnect the CPU For users who are more comfortable working with the inside of their computer or who have built their computer one last recommendation before assuming hardware is bad is to reseat the CPU by removing it and putting it back into the computer. Bad motherboard, CPU, RAM, or power supply If after doing all of the above recommendations you continue to have the same issue unfortunately it is likely that you have badMotherboard, PSU, CPU, orRAM. The next step would be either to replace these components or have the computer serviced. If you plan on doing the repairs yourself or you are a repair shop it is suggested that you replace the Motherboard first, RAM, CPU, and then power supply in that order or try swappable parts from other computers. Hope this helps.

Having it turned off restart it and keep pressing the F8 key. A repair screen should appear if the hard drive is any good. If not your hard drive has failed

Your computer has memory problems. First checkvideo. If video is working, you'll see an error message. If not, you have aparity error in your first 64K of memory. First check your SIMM's. Reseat themand reboot. If this doesn't do it, the memory chips may be bad. You can try switchingthe first and second banks memory chips. First banks are the memory banks thatyour CPU finds its first 64K of base memory in. You'll need to consult yourmanual to see which bank is first. If all your memory tests good, you probablyneed to buy another motherboard.
Clean the ram and the ram slot .then fit it again.
Hope it will help you.

Sounds like a memory issue. Make sure the memory is securaly seated in the memory channels, make sure it is the right memory for the motherboard and that it is not faulty.
To test the memory remove one chip and try booting, if that does not work then put it back and try removing the other and try booting again. If it still does not work, make sure again it is properly pushed all the way down (You will hear and feel the tabs on the side securaly click into place, also the memory only fits one way, make sure they aren't backwards) and by what I mean wether it is the right type, DDR2 will not fit in a DDR3 socket as an example. Please feel free to tell me if this was helpful or not so I may add additional help if required. Thank you.

Your motherboard is complaining. Try re-seating the memory and rebooting. If that doesn't help, you should consider another motherboard. You could probably get away with just replacing the CPU, but that's not too cost-effective. Its just time to upgrade!
