I have a brand new Dell running Windows 8 and connected to a new Insignia TV via VGA as its monitor. Everything worked fine the first week, but now anytime I leave it for awhile and come back, the monitor won't wake. I've tried the mouse, the keyboard, checking the connections, even the power button on the monitor won't get it to turn off and then back on. I've had to start unplugging and re-plugging it from the outlet to get it back on. Some of the similar forums mentions things like BIOS and mobo, which I'm not familiar with. I'm a recent convert from years of using Macs, so please help walk me through some options with basic language. Thanks!
