I have a Dell desktop -- XPS -- OS Windows 8.1.
A few days ago, I got a failure message on my computer that said it needed to restart (I wasn't using the computer when it happened; it was sitting idle). Upon restart, my keyboard wouldn't work. I borrowed a friend's keyboard today and logged in. Things looked OK. I did some work on it and left it on. When I went back to use it this evening, it won't "wake up." The light on the borrowed keyboard isn't turning on, the mouse light isn't on. The power light is on (white -- not on standby, which is yellow). The monitor light is on sleep mode (white) and when I click the button on the side it says it is not receiving any input from the computer.
Since I couldn't get it to wake, I did a hard restart (held the power button for eight seconds), then let it sit for a few minutes before trying to turn it back on. The power light comes on and the fan runs, but nothing else is on.
I don't think there's a hard drive light on the computer, so I can't tell if it's working.
Thanks in advance.
