SPdif out

Aha, spdif out on the motherboard. You can create a bracket from it with high quality audio, or you can attach it to the video card. Problem with this is nearly none of the manufactures for video cards package their cards with the proper cable. I shall later post how to solve this problem, and how to go from any spdif to a 2 pin spdif on a graphics card. (Only on cards that support them, usually one's that support 1080i/p or have an hdmi socket/plug/adapter.) Also note that audio can travel through DVI to HDMI.

Are you sure it's the motherboard?....

Remember, the motherboard can be a source of a lot of computer problems. With this in mind, a lot of support from companies will send you back your product after diagnostics saying the motherboard is bad. When you get someone saying that, check for yourself. Open the case and look inside, is there a lot of dust?... If that's the case, then you'll want to clean it out, like you should every 2-3 months depending on your environment. Shop computers should clean their computers every month. What was the problem with the computer? Not starting? No video?... Look for the true source of the problem before you check anything on the motherboard. If there's no video and you have onboard video, there is no fix for it, besides getting right drivers. You could install a video card into an available slot but there still could be other errors on the board. If your computer dosn't start up you should always assume the power supply is the source of the problem first. Look at it, does the fan spin up? Does the motherboard have a green light?... To test if it's the power supply you could get a paper clip and shove it from the green wire to the black wire next to it and see if the fan spins up... but for amateurs I don't recommend this.

Just all in all, make sure it really is the motherboard before you go buying something you don't need. You may have a power supply problem that'll cost you $20. Or you could have a CPU problem and save yourself $100 by not replacing the board. Always be sure of yourself before you make that final spending decision.
