Just bought a 990FX Extreme4.

It was working fine for a little over month and now my usb devices are constantly going in and out. I hear the noises the pc would make on plugging in or removing a device and my mouse and keyboard will randomly stop working. Sometimes they wont come back and I have to switch usb ports.

Also my sound does the same thing, I hear a scratchy noise and then the audio drops out. This usually requires a reboot to get sound back or I can switch to using my video card over hdmi for audio.

Tried restoring a backup to a known time period where things were fine and it didn't help so pretty convinced its something with the motherboard. I have all the drivers from asrock's site on their latest versions and bios is up to date.

Please help
