MB: GA-990FXA-UD3 rev 4.1
CPU: AMD FX8350
PSU: EVGA NEX650G
GPU: ASUS STRIX-GTX970

Problem:
Just put the computer together 2 days ago. Worked fine at first, initially ran for 5 hours with no issue, playing music. Yesterday I began to run into issues where if sound was playing, the sound would become glitchy and then cut out along with all usb devices. If left alone for about 5 minutes the computer BSODs. I reinstalled the USB drivers and got the most up to date realtek drivers from the realtek site. I ran the memory check tool and did a cpu stress test with no issues. After that it ran all day with the speakers unplugged and then ran a game (with sound) for 90 minutes without issue. Today again I was working on another computer and playing pandora when it happened again about about 1 hour. Sound became glitchy and all usb devices stopped functioning.

Summary:
When speakers are plugged in and sound is playing, everything crashes.
Everything seems stable without speakers.

By any chance are they USB speakers? If so have you tried reg speakers that plug into the speaker ports?

They are not usb speakers and they plug into the speaker port.

Note that the issue happens if I plug them into the speaker port or the speaker port on my blackwidow keyboard (which connect to the speaker port as well).

Any guidance would be greater appreciated. I have been managing to get by using the front audio port however now that is also crashing the computer.

The only other thing is the speakers could be shorting out. That is way it is crashing the computer. All it is doing is sending a signal to the speakers. There really no power that goes to them. Where it is happening to front and back connections it has to the speakers.

So the back audio port was happening both with speaker and headphones. I have only been using headphones for the front audio port. I will try using the back port with headphones and see what happens.

If you are having problems with the headset too then it might be the motherboard.
