Windows 10: Monitors Put to Sleep, Doesn't Wake, Though System's Still Active

Been going on for a couple of weeks now.

First, I had to add this: because I have a display port connected monitor, I this program (Turn off your notebook LCD with one-click | Redmond Pie) to put my monitors to sleep instead of switching them off. 2 monitors, 1 hdmi, the other on DP.

Unlike hdmi/dvi/vga connections, display port monitors seem to be treated as a total disconnect when it gets switched off, which means it keeps causing windows to refresh the screen and readjust the desktop primary/secondary desktop and rearrange the icons, which is extremely annoying.

About 1-2 weeks back, my computer would automatically force the monitors to go to sleep.

The system itself is still active. Whatever programs are playing sounds will continue. I can turn on and off the caps button, etc. However, I don't seem to have control. Ctrl-alt-del is unresponsive, and blind clicks to browser windows playing videos doesn't seem to work.

It could be a hardware issue.

Sometimes when it triggers, there will be a split second buzz, where the sound the pc is playing hangs for a second, then it continues, but the monitors go to sleep.

Almost always, just before the monitor sleeps, the monitor goes black, a console cursor appears at the top left, then they sleep.

It looks very similar to what the program I downloaded does. I've changed the file name, but it still happens, so I doubt it's that program that's triggering.

I must always do a hard power off to restart.

Does so randomly.

Sometimes, it happens a minute after I reboot. Other times, I can get through a whole day without issue.

I've tried playing around with power options, resetting them, resetting then changing it back, and now switching it off altogether. Doesn't work.

I tried looking at some error logs but it seems like gibberish to me. I hope someone can help if it's not like a faulty graphics card or something.

Thanks

Sleep problems awaking.

Installed the latest update Windows 10 on PC last week & Monitor doesn't wake from sleep. Monitor starts to wake but then appears 'DVI no signal' and monitor closes down. The PC sound as though it is waking. Maybe upon wake the PC is sending the vidio
signal to the wrong port???

Any suggestions??

 

HP Pavilion 1907 w monitor won't wake after sleep.

Windows 10 HP Pavilion 1907 W monitor won't wake after sleep. Have to pull power cord to get it back. Power button on monitor does nothing. Sleep key puts PC to sleep but when it comes back the monitor doesn't. Worked fine before converting to Win 10.

Was on Win 8.

 

Hi shadowoflight

If you disconnect your monitor display port from PC, count to three and reconnect does it come back?

What graphics card are you using or is it integrated?

Just triggered gain as I was reading your reply lol.

nope, doesn't come back.

a dedicated card

 

Have you checked Windows Update to see when last set of drivers was install for it. Hopefully it will coincide with when trouble started.

Try rolling back driver.

Just reinstalled windows 10. Everything was fine, then I started a game and tried to change the streaming resolution of a twtich channel.

boop.

Pretty sure it's a problem with my gpu now. =.=

 

Well that is not good. Does your card have any diagnostics you can run? (Temperature).

Have you looked at PSU?.

 

Hmm.

I've isolated it to a program called Boinc - Berkeley Open Infrastructure for Network Computing.

Seems to be a problem when it uses the gpu to crunch data. I've suspended gpu usage and this problem has completely stopped. Been a few days since it last happened.

I guess I'll have to check in with them.

 

Great. I run Boinc too - Looking for cancer markers. I don't allow it access to GPU.

Thanks for posting your solution. If you are confident that it is fixed please mark thread solved so others will find.
