It looks like you have some open programs running, which can confuse the report. But it states the HD Audio is not allowing the system to sleep. If you are streaming or maybe playing audio, it would make sense.
Do the Bluescreens occur when the system is about to go into hibernation, or sleep? you might try turning off the Hibernation ability for testing. I do not know what would cause the hibernate files to overlap, but possibly it is related to memory management.
Someone else should be along shortly that might have a better idea of what is going on.
