Possible causes:


Overheating as @Dan Neely says
Physical issue with cable connecting LCD to motherboard
BIOS not initializing GPU correctly, try BIOS update (this is a long shot)
Motherboard needs to be replaced (bad chipset, or bad something else that would cost more than replacing the motherboard to fix)


Netbook screen display is garbled (has black/white & horizontal line patterns, screen freezes, and/or wrong display position)
I am planning on going out to Pakistan soon and I am wondering if I should bring my Xbox 360 for a friend that stays there,

Would the Pakistani games work on my Xbox 360?
