Hi everyone

Im having a problem with my computer crashing when its connected to my external screen.

I have a Sony Vaio E-series VPCEB2S1E-BQ with a ATI Mobility Radeon HD 5650. The driver, which my system says is up to date is version 8.723.8.2000.

When i play games, mostly League of Legends, I experience that my computer crashes. It freezes and the sound gets all moshy and I cant do anything else but reboot my computer.

I only experience this when im using my external screen, so im quite sure that it has something to do with my graphics card/driver not being able to boost the resolution into 1920.x1080 (Laptop screen is 1366x768)

What do you think it can be guys and what can I do?
