I own a Gateway MD2614u and it has been true to me for the last 2 years, but now it has a little problem. The screen turns black and will not come back on unless I hold down the button and restart the computer. It is not the backlight on the screen and it is not the screen itself. I hooked an external monitor to it to confirm and it made that screen black as well. I was using Windows 7 Ultimate X64 on the machine however I reverted it back to Vista Home Premium X64. The problem reoccured even with its intended operating system. Does anyone have any ideas what the cause of the problem is? I don't believe it is the cable or the monitor.
