So I updated my driver from Crimson
it was good at beginning but when i let my computer idle for a while
it just became no response, screen froze at minutes ago when i was doing other thing
Hard drive-activity LED was totally blackout too, then i only have to restart it
This problem only happen when i let my computer idle, and i have tried clean install
It was fine when i get back to Crimson
