My Dell XPS One 2710 (All-in-One desktop PC) will not boot and only gives me a black screen. When I power on the machine, the video display flashes for a couple of seconds, then is unresponsive. I don't get the Dell logo -- just black screen. The hard drive and fan are running on the machine, so this does not appear to be a power supply problem. I've unplugged all peripherals. I've also attempted to connect another monitor to the all-in-one, using the HDMI out port, but I still only get black screen.
I upgraded the machine to Windows 10. All seemed to be working well for about four weeks. This week, the machine began behaving oddly, going unresponsive during simple activities such as Web browsing. Finally, it started black screening on restart, and now it's in the current state of perpetual black screen.
I have Windows 10 installation media, and I'd like to do a clean install of the OS. All of my data is backed up. But I can't get the machine to acknowledge the installation media, which is on a USB drive. Pressing F1, F2, F12 on power up does nothing.
Thoughts or recommendations?
