I am having a problem with a all-in-one (Lenovo B500) that goes blank randomly. It usually happens either right before the login screen or about 10mins after logging in or when I open a program (Game)

When the screens black (sometimes flickers) you can see a dim image of what I am doing sometimes the screen stays black for a couple mins and I am forced to holding down the power button. I've tried updating drivers and the black screen still occurred

Also after the desktop loads i start to get green pixels mostly around my desktop background and start bar

Thanks

Jack
