most likely irq sharing and/or interference from another device in you PC such as your video card.

or just a cheap onboard sound card ..maybe get a pci sound card

Or just unplug your speakers over night

It's most likely one of 5 things: interferrence from another device/part in the computer, bad power supply, faulty power bar, feedback from a device/pice of equipment near your speakers, or overall 'unclean' power within your house (high powered equipment on the same line connected the one your computer is hooked up to can do this).

Things to try:

Use headphones. This will tell you whether or not your speakers are faulty, or at least tell you if something is interferring with them

Try plugging your speakers power cord into a different wall outlet seperate from a power bar. Some cheap ones can cause feedback, as well as some expensive ones that are going bad. I've also seen this happen with UPS systems even when they are perfectly fine otherwise.

Try using your speakers on something other than your PC, such as a walkman.

Onboard soundcards suck. I would suggest upgrading to a standalone card anyways, but if it's a question of money you can always buy/borrow a card for testing, and return it if you still have problems.

If money is a factor you may be able to test a new power supply unit by taking your PC to a friends place (or having that friend bring his PSU to yours), or to a repair shop. Test your machine on a different PSU (new or old.. don't matter), and if you have the same problem it won't cost you anything (some repair shops won't charge you as they 'technically' haven't provided any service or repair for you.. ask them first though if it'll cost you anything to try out a new PSU).

Before you do the above suggestion try your machine out on THEIR speakers first (you can take your speakers with you too). If it sounds fine using their power source then you'll know that something might be wrong with the power at your place.

BTW: if your sound is still bad, even when playing on their speakers, or if you are using a new PSU, then this will tell you that the problem is originating from another source in the PC. If so, it's most likely the motherboard.

Check with your local power company, and see if they can come to do a test on all the lines and wall outlets in your home. You may find that some are tied in with high powered equipment, or your lines are just plain bad. However, this option will cost you money, and should be the last resort. 'Course, this is also your call as you may not want to go this far for testing.
