!!HELP!!
My G75VW with 16 GB Ram, 256 SSD, 1TB HHD, 2.30ghz -(3.30ghz),3 GB graphics GTX 670M

has screen glitchs on any game when not plugged into power. This makes the computer slow down the game and glitch.
The computer even glitchs when playing Minecraft. Works with all my games fine when plugged in. I have restored it many times and it does not changed any thing

P.S. I am using windows 7 Home Premium and can i upgrade to a 3D screen because i have reached the requirements.
and if so please tell me at sketchy28@gmail.com

THX:)
