I have a HP pavilion dv 6 that randomly shuts about every month.

Is it every month?

Are you saying your notebook is always on?

This issue can occur due to hardware failure or conflicts.

I will suggest you to run windows memory diagnostic tool using steps in below link:

Do you receive error "Windows has recovered from an unexpected shutdown problems" or Blue screen?

I will suggest you to perform startup repair:

Perform the startup repair eventhough there was no problems in starting up? Also, how do I perform the startup repair?
