Symptom: Almost every hour or more, my system will halt all action and the last played sound will loop. Crashes can occur on normal browsing and gaming. Only a cold reboot will resolve, so there are no minidumps. Checked event viewer countless times with leads.

Here's a list of everything I've done

    1. Reformatted Windows 8.1 (TWICE)
    2. Reinstalled ATI drivers with sweep (A LOT) - beta and normal
    3. Reinstalled sound drivers and up to date
    4. Moved GPU to the next PCI-E slot
    5. Replaced power supply with a spare - 650w
    6. Switched slots for RAM and Memtest 7 passes
    7. Removed CPU overclock - tested and worked for 2 years before this began
    8. Not an overheating issue. CPU max load - 78 GPU - max load 69
    9. Cannot force crash by stressing furmark, memtest, prime85. Everything passes
    10. Removed GPU and ran off integrated but still crashed.


I'm running out of things to do. I am going to try and reseat my heatsink and hope for the best. I'm beginning to suspect a dying motherboard? Although there are no signs of it deteriorating in health. I'm afraid of buying a motherboard to find it still occuring.

Just because the memory passed memtest does not mean it's ok. Doesn't mean it isn't either. I've found memory on numerous occasions that passed 7 or more passes with memtest but when taken out of the equation, turned out to be the problem. Try removing one of the modules and if the same problem occurs replace it with the other module and try it. It's not likely to cause any sound loops though, although anything is possible and I've seen stranger things.

In reality, if you're using onboard sound and everything else is pointing to the motherboard, I'd be inclined to agree that it was the most likely culprit. If the chipset for the sound is having issues it could cause just about the same issues as any other part of the motherboard or RAM. Maybe try a PCI or USB soundcard and disable the onboard sound, or just disable the onboard sound, and see what happens.

I came back to this thread and it is exactly as you have said. Two days ago, I removed my memory modules one by one and found the culprit.
Don't always trust Memtest indeed! Thanks darkbreeze

No problem at all. Anytime. Glad you found the problem. Good luck with the replacement. I'm sure you'll be fine with a new module.
