Windows 10 Desktop PC will not wake up at all

Yesterday my Dell Desktop PC with Windows 10 64-bit was refusing to wake from its sleep state. I finally got it to come on by not only powering it off, but unplugging it and waiting a few seconds. It came back from cold boot, but that is better than nothing. I then, as many suggested, ran the power troubleshooter.

This morning it will not show anything on the display. When I power up, I hear the diskdrive work, I see a little outboard USB hub light up. On my monitor I am able to see the message that no signal is coming from my PC, so I figure my monitor is ok (and is set not to VGA or HDMI, but auto).

I have tried unplugging and trying to boot with F2 held down, and again with F8. Nada, nichts, nichevo. I booting with a linux ISO in the disk drive, and with one in a USB port. Again, nothing.

Up until yesterday everything, including sleep, was working fine.

Might I ask if anyone has any ideas? And thanks.

Do you have a Video card on hand? or a friend that could let you test it out and see if the onboard video is just not putting out a signal? – NetworkKingPin – 2016-04-26T04:50:04.947

The no signal message on the monitor makes me think that it may be a connection problem between monitor and computer. It's possible that something may be heating up or shaking a connection loose. If your monitor is connected via VGA/HDMI cable, have you tried replacing the cable with a new/different one?

Thanks, UnixCurious. Not another cable,no. I did disconnect the cable I have, and the monitor then said "there is no VGA cable attached." When I put the cable back in place, it said once again "there is no signal coming from your computer." From that I am guessing that the cable is OK, because the monitor is recognizing it is a VGA cable (right?) – birrellwalsh – 2016-04-26T04:52:01.557

Well I'd say to try with different cables, both HDMI and VGA. They're pretty cheap, and it never hurts to have extras around if you don't already. – UnixCurious – 2016-04-26T05:04:45.680

Also, make sure to check the cable for visible damage/defects. – UnixCurious – 2016-04-26T18:24:04.767
