Laptop restarts when connected to TV via VGA cable

[bunyoka]

Hi All,

I've got an ASUS K53 laptop and it's connected to my Sony LCD TV via a VGA cable. It is working perfectly when I trying to browse pages, watching movies, etc. But when I start to play games it is rebooting without warning after around 5 minutes.
It is working fine when it's not plugged. I have had this problem for a year now, but was doing fine before.

Any help appreciated!

Might try reinstalling the GPU drivers.
