Question about HP Pavilion Media Center a1330n - AMD Athlon 64 2.4GHz Desktop Computer (Open Box Product, Limited Avai... (EL466AAABAOB)
I have a very frustrating situation. Which is, I have been unable to resolve a grounding problem which results in a low-pitch humm when I connect my pc to my stereo system using an audio cable. It does NOT occur when I connect my iPod to the stereo using the same cable. There is no humm when I normally play audio on my pc. I have an HP Pavilion (Media edition) and a Pioneer stereo. I connect to the “CD” bank on the stereo since that is (presumably) “digital”. I have sent the signal from the PC to a radio via a wireless FM transmitter and then connected it to the stereo and there is no humm. Therefore, I believe it’s a ground fault from the “hard-wire” connection. I have done the following:
This ground loop isolator from Radio Shack was suggested when I did a search:
It says it has the 1/8 jack adapter, so it should plug right in!
I'd be curious to hear about the results if you try it.

Computer RAM (memory) related issue.
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. Information about ESD and proper grounding techniques are found on our ESD help page.
Remove added memory
If you've recently added or tried to add additional memory to the computer and have started getting these beeps. Remove all new memory you've added to the computer. If the computer works fine after removing the new memory you're encountering either an incompatibility or defective new memory.
Open computer and reseat memory
Sometimes when the computer is moved or over time a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the computer.
Swap memory location
If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.
If you have more than one stick of memory try removing all but one stick of memory and boot the computer. If this does not resolve the issue try removing that stick of memory and try one of the other sticks of memory.
Try another computers memory
If you have access to another computer that uses the same memory, try using its known good memory in your computer.
If another computers memory works you know that you have bad memory. If another computers memory does not work and it is compatible with your computer unfortunately your motherboard or the slots on the motherboard are defective causing it to be unable to properly read the memory, which means the motherboard will have to be replaced.
If it is determined the memory in the computer is bad we suggest that you replace it.
