Black screen after login Windows 10


Jan 1, 2017
First of all, happy new year to you all.

PC specifications:
CPU: Intel Core I7-6700k
Motherboard: MSI Z170A-G43 PLUS
Ram: Kingston Hyperx Savage (2x8 GB) DDR4
GPU: MSI R9 390
SSD: Samsung 850 EVO 250GB
HDD: Seagate Barracuda 7200RPM 1TB
PSU: Seasonic M12II EVO 620 Watt
Case: Cooler Master Mastercase 5
CPU Cooler: Deepcool Frostwin V2
Fans: 2x standard Cooler Master Fans + 1x Alphenföhn Wingboost 2
Monitor: Dell Ultrasharp U2715H

Running latest version of Windows 10 pro 64bit
All the drivers are up to date, I double checked that. (no regular updates either)

Now here is the problem.
When I boot up windows it goes as far as the login screen, when I type in my password I see the desktop for a split second and the screen goes black. There is no mouse cursor and ctrl+alt+delete doesn't work. I found out that when I throw my pc in sleep mode before logging in, it will load everything just fine after logging in.
I've disabled some autostart programs and made sure that my gpu was back to it's original clockspeed.
Does anyone know what to do because I am at a loss...

Thanks in advance and sorry for my bad English,

PS (if something is unclear, just ask, English is not my native language)


try doing a clean boot and see if its windows or a start up program. If it works, it means its one of your start up programs causing probelm and you need to add them one at a time to see which:

try removing all extra usb devices or speakers before you start as explorer could be hanging waiting for a device (but usually the PC will respond to ctrl alt del after this)

right click start button
choose command prompt (admin)
type SFC /scannow and press enter
once its run, copy/paste this into same window - it needs to be exact:
DISM /Online /Cleanup-Image /RestoreHealth

SFC fixes system files, DISM fixes the files SFC uses to fix them, so if SFC had problems first time, re do it and restart PC

you could try turning fast startup off: but I don't see it being the problem
