I have an Vista PC with an Intel DG965RY MB (onboard sound). The other day the speakers started whistling. The speakers stop when unplugged from the tower and work flawlessly when hooked to an MP3 player. The only thing I can think it would be would be the MB itself. Either the southbridge chip itself or a connection somewhere. Anything else you can think of that I should check before I swap it out? I could add an audio card, but if it is the chip I am afraid it is just the beginning, after only 1 year and a half :dunno:

Make sure all your power lines are away from the speaker cables. Speaker cables are like antennas and will pick up interference. Check your ports and connections are solid. Check your fans. Move internal wiring away from the chip. Separate computer from other sources of interference. Try another outlet for the computer (electrical line noise).

Buy cheap Creative Labs and call it a day.

Make sure your cable or DSL MODEM is a few feet from the PC and yes check that the wires from the PC to the speakers isn't near the power packs, wall warts, or MODEM/Router.

You can try removing the sound device from your hardware configuration, in the control panel, and having Windows automatically reinstall it. The driver may have gotten damaged.

Otherwise it is repair shop time. I had a sound card's driver get corrupted and had a heck of a time finding a upgrade to work on an older version of windows once.

Disabling the built in sound and adding a separate sound card my not be possible with that motherboard, only a good tech will be able to tell for sure. Unless you are the adventuresome type and want to try the replacement yourself. Maybe the motherboard is available on Ebay if one is needed.

Another problem popped up. The NIC is causing it to fail to boot. It goes to the splash screen and then shuts off. Boots fine in safe mode. Will only boot into normal or safe w/ network if the onboard NIC is uninstalled or disabled. As soon as the the driver loads, instant shutdown.

I updated the driver, no dice. I uninstalled and it boots, as soon as it finds and loads the driver, shutdown.

Right now I figure it's either a Windows update problem (not likely) or the southbridge is dying slowly. :dunno:

You have a major motherboard melt down on your hands, time to find a replacement board on eBay, as much I hate saying use eBay. Or replace the PC and recovery the hard drive data to the new hard drive Via Laplink's PC mover software.
