Windows 10: Monitors blink off black screen and on multiple times after waking up from sleep mode

Hello Friends,There is a recurring issue I am having with my monitor setup. Issue:All monitors will blink on waking up from sleep mode then blink off black screen, unresponsive to key commands for a second or two. This repeats a couple of times before my monitors finally stay on.I've seen other posts that reference "flickering" but my issue does not seem to present like that. It seems more like my monitors/system is trying to calibrate the monitors to my system settings and is blinking on and off to bring them in sync?.Info:3 monitorsWindows 10 up to dateNvidia Geforce GPU 3080Gsync on

Multiple computers won't wake out of sleep mode/start in sleep mode

I am trying to reinstall Windows with a USB, following the steps, and I cannot get anything on the monitor. It is black and the lights are blinking like it is in sleep mode.

Well I actually have replied, I did all of step 1, and went onto step 2, followed the instructions for installation from another PC from a USB drive. I have Windows on the USB drive and tried to install on the problem computer. I am not sure what the disconnect
is here. Since I was clear (I thought?) about the problem in my OP, I feel like actually you are the one who did not read what I wrote, especially when you told me to simply restart/wake up the computer.

So if you cannot help that is fine, and I guess I will have to go elsewhere. I am seeing a lot online about Windows 10 causing this issue and so that is why I am here. It is the one consistent variable with the problem I have had now with two computers back
to back - they go into sleep mode and will not wake up no matter WHAT I do (yes, I do know how to reboot a computer and wake a computer up out of sleep mode, obviously this isn't about me just needing to "wake up" the computer).

POST 1: My computer would not boot up, and I tried everything I knew to get it to work to no avail. Got a new computer, everything was fine until - it went into sleep mode and wouldn't wake up. Reboot = sleep mode and won't wake up. All I have is
a black screen. I've tried switching cables, plugs, monitors. What is going on? I feel like I am going crazy.

POST 2: I tried the first few steps with no luck. The screen remains black, there is no change/response. I am not sure I will be able to do the next steps such as Windows installation media.



POST 4: Thank you so much I want to do the installation but I don't have a windows key this is a refurbished computer that I didn't originally buy

POST 5: I am trying to reinstall Windows with a USB, following the steps, and I cannot get anything on the monitor. It is black and the lights are blinking like it is in sleep mode.
