So I have a problem, any help would be great. I have a new computer, like 2 weeks old. I have turned off sleep mode so I only have the shut down button and the restart one. When I shut it down, no problem, turn on no problem, its very fast as it should be. Now when I want to do a restart, it shuts down, then powers up and goes into sleep mode... and wont wake up, or I dont know how to! I tried to just turning the screem of and on again, and it comes up with "going into sleep mode"... what to do? some programs tell me to restart them to make them work, (they do not work when simple shutting the PC down and restarting it) it requires a complete restart... but as said it goes into sleep mode..
Any help much appriciated

Quick summary and context (for the archive): describes a new Windows 10 PC where Shutdown + Power‑on works fine but Restart powers back up and the display immediately shows “going into sleep mode” and won’t wake. ’s suggestion that the monitor is reacting to a bad video signal (out‑of‑range) is a common and useful lead — this thread below gives a focused checklist to prove whether the machine is actually sleeping or the display/output is failing, and what to do next.

First, decide whether the system is asleep or only the screen is blank:

  • After the restart, press CapsLock or NumLock and watch the keyboard LED. If the LED toggles, the PC is awake and the problem is the video/output (not sleep).
  • Try the built‑in quick fixes: press Win + Ctrl + Shift + B (resets the graphics stack), Ctrl + Alt + Del (see if the security screen appears), and cycle projection with Win + P then P then Enter. These are documented recovery steps from Microsoft. (support.microsoft.com)

If the above shows a display/driver problem:

  • Reseat or swap the video cable and try a different monitor or the motherboard video output (if available). A monitor “Input not supported / Out of range” message or fixed blank that clears when power‑cycling the monitor points to a driver/EDID/refresh‑rate mismatch.
  • Boot to Safe Mode and roll back or reinstall the GPU driver (clean uninstall with a tool like DDU from Safe Mode is a reliable method). Microsoft’s blank‑screen guidance explains Safe Mode and driver rollback steps. (support.microsoft.com)

If you suspect power/sleep state or firmware interactions:

  • From an elevated Command Prompt run these diagnostics:
    powercfg /a
powercfg /lastwake
powercfg /devicequery wake_armed
shutdown /s /t 0

    powercfg /a and the other powercfg options report available sleep states and last wake sources. To avoid hybrid/hybrid‑shutdown oddities try a full shutdown with shutdown /s /t 0; Fast Startup is a hybrid behavior and does not apply to Restart (Microsoft documents this and other Fast Startup workarounds). (learn.microsoft.com)

If none of this helps, update BIOS/UEFI, chipset and video drivers (from the PC or GPU maker), and contact the PC vendor under warranty — a hardware/firmware bug on a brand‑new machine is possible.

Just one thing. That message is likely the display going into sleep mode. I've seen that when the PC is working fine but the video mode is out of range of the display. The new to PC person reports the PC is going into sleep mode which is a little off the mark.

To me this sounds like the maker of the PC needs a call to sort out the bum PC. Maybe it's just a driver issue but they should fix it.

commented: I think I will probably call the place where I bought it and see what they have to say. Thank you for the help +0
