Hello,
I have a *used* PC Chips / Amptron M830LR Motherboard. It has two pair DIMM (DDR and SDR). This mainboard has five 32-bit PCI slots, one AGP slot and one AMR slot. It also has onboard sound (SiS 7012). I am running an AMD CPU at around 1.4 GHz.
I have 256 MB SDR RAM Installed. The other SDR Slot is Damaged.

The Problem:
I am not using a AGP Card. I am using an old PCI "ATI Rage II" Graphics Card w/ 4 MB RAM and the onboard SiS 7012 Sound. Regardless if I am using an older OS Like WIN98SE or a newer one like XP Pro I am getting audio noise on top of my normal sound whenever there is any graphic heavy content along with audio. (Like playing a DVD or Media Player with Visualizations or a video game).

I *do not* thing that the problem lies within the onboard sound because I tested a good working audio card from a different system and still had the problem. I *do not* think that the problem lies with the 256 MB SDR (only) of memory because I tested different units of RAM in the same slot. I even tried an old OS that is not as Memory hungry as XP but I still had the problem. However, since the other DIMM slot is damaged could it be a problem??

The only thing I can come up with is trying an AGP card with some onboard memory but do not want to purchase one if I still end up with the problem.

Any ideas?

Hello DGDecker, welcome to PCHF.

Media Player Visualizations, video gaming.. on a 4mb ATI Rage II graphics card? It's just... not gunna happen! The onboard sound isn't too clever, but your graphics card is your main problem here. Since your graphics card won't be able to process this much information, most of the processing power is dumped onto your CPU. The result = not enough processing power for everything else, including sound.

Thanks madmonkey... That is what I was afraid of. An AGP card for the cure.
