Well there's your problem. Whilst it's a bit crappy, just don't ever ever use your reset button. If you had read through here you'd know that people recommend not to use it because it almost always triggers a boot loop. I've got into a loop twice, both time after using the reset button. I never use the reset button now, and my motherboard is working fine.
Sure, it shouldn't happen, but I'm not entirely sure they're going to fix it and I don't think it's worth switching motherboards over, so I'm just going to live with it.
