monitor is blinking and screen goes black

and you said if you leave overnight. It sounds like this happens even when you sleep for a short duration, correct?

Maybe its Hibernation. Quick test.

To a command prompt (admin) or Power Shell (admin) enter

powercfg -h off

to reverse command change the word off to on.

Try with it off over night.

After re-reading this thread....I see no mention of installing said software/driver package for your PCI Wifi card. Have you installed it? I see it's a dual band setup....is it 2.4 ghz or 5.0 ghz....meaning is it one or the other or does it do both at the same time? Which one are you connecting to? What does your modem router support?

I have the TP link drivers and software installed, I am only using 5ghz. My modem and wifi card supports both.

I just tried it, didn't solve the problem.

Might be worth having a look at the TP link forum, seems there are issues with drivers and Win10, could possibly be related? Archer T9E with Windows 10 - Page 2

Possibly, I should problably also mention that yesterday and today I had to remove the graphics card, shut off my computer, unplug the dvi-d cable, connect the graphics card again and connect the cable to make it work. I didn't have to remove the wifi card this time. I'm guessing that its the graphics card or the pci-e slot on the mainboard that is creating the problems?

Have you tried an older driver. I will mention that there are a few threads with screen not turning on after sleep, screen being blank after sleep.

Just to see, the next time you wake and screen does not come on, unplug the cable from the PC, wait 5 secs and plug back in.

What happens?

I just did that today. It worked. The screen stops blinking if i reboot the pc, unplug the cable, wait 5 seconds and connect it again. Strange. What is causing this and how do i fix it?

Not sure what is causing or fix. What Graphics card on onboard unit do you have.

A friend of mine has same issue and he noticed if he disconnect and reconnected it work. Can't take credit for that. There are other threads as well where screens are either white or black after sleep.

I would think this has to be a driver issue.

If you could post back what you are using.
