I just bought an HP Envy 17 - 3090NR 3D laptop, loaded with Windows 7. When I am playing a game, for example, a game through Steam, after 10-15 minutes the CPU usage of everything on my computer suddenly skyrockets, causing the game to freeze up and distort for several minutes. Everything else on my computer runs incredibly slowly at this time as well. After a few minutes everything goes back to normal, but the problesm start up again after several minutes.
This has been happening ever since I bought it. It's a brand new laptop. No error message has popped up.
