I have cleaned the fans, its not running hot, I have the bottom elevated for air flow, I've got an additional monitor hooked up and on its own the screens turn black but not the computer. The only thing I can do is hold the power button for about 30 seconds and restart it. My virus protection is up to date and this laptop in NOT on the internet...I use it to build digital maps. Help please.?.?
