Windows 10: Black Screen then Computer Logs In

Dear Microsoft Team


I have Windows 10 Home.



I have graphics card: AMD Radeon R9 200 Series

Chip Type: AMD Radeon Graphics Processor (0x67B0)

Speakers (Sound Blaster X-Fi Xtreme Audio)

Digital Audio (S/PDIF) Sound Blaster X-Fi Xtreme Audio





The problem started after I took my computer to have the following put into my PC:



Gigabyte Z370 AORUS gaming K3 motherboard

Processor: Intel® Core ™ i5-8600 CPU @ 3.10GHz (6CPUs), ~3.1GHz

SSD: Supply Samsung M.2 NVME 1TB Pro version

DDR 4 16 GB 3000



I have no trouble logging into my computer. Everything works fine.



Then after a few hours or so the screen suddenly goes black. Then the computer begins to log back in by itself and everything is fine again. No problems.



Then in about an hour later, the screen goes black again. The computer restarts and logs in again and everything is fine. Everything works normally.



The problem is I am now getting this black screen and logging back in about twice a day.



This all started after I went to computer shop to put in a new motherboard, processor, SSD.



Any ideas, please?



Many thanks.

:)

Black Screen after Log on

So this is not a BSOD ? Have a Windows 10 disc or USB Flash Drive made ? How are you getting to task manager Ctrl.+Alt+Del ? Any cursor on screen ?

 

Black Screen after Log on

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable
