Hello and thank you very much --
Yesterday the cursor disappeared so I turned the pc off manually. When I turned it back on after a few seconds all was OK. Cursor disappeared again, so I tried the same thing, but the computer now won't turn back on at all.
The start button lights up amber then immediately goes out. No sounds. I have unplugged and plugged back in all the cords from wall, router, modem. The lights on modem and router are all normal, The laptop I am using as I type right now is hooked up to the same system, I'm not using the laptop wirelessly. I have also unplugged the power and held down the start button for 10 seconds as was suggested on Dell's website. But pc still won't respond.
The pc that won't turn on is a Dell 8900 which I bought 6 months ago and has worked perfectly up to now. I use Windows10.
What should I do next?
I have posted this request to Dell, and the online company I bought it from too.
