Driver Power State Failure Minidump Analysis Requested  

Looks like your audio driver is the cause, but it's hard to tell from just 1 minidump.

I'd suggest updating it, and maybe upload a few more dmps for us.

Although one of them appears to be caused by your anti-virus AVG, the rest point to memory problems.

I would strongly suggest a memory test. Download a copy of Memtest86 and burn the ISO to a CD using ImgBurn. Boot from the CD, and run at least 5 passes.



If Memtest doesn't turn up any errors, consider switches anti-virus to Microsoft Security Essentials and updating your sound driver.
