For the last two-three days I am facing problem with my Samsung PC. Some times it turns to black screen, even while working in word or internet.

  1. Initially it blinks (some times), later turns to black screen completely. Restart is the only one solution.
  2. After initial blinks, I can see that task bar in black color, even though some programs are in open stage.
  3. I scanned with anti virus, malware fighters but no issues found.
  4. It happens both in plugin or in battery power.
  5. some times it happens in each couple of minutes. But now I am working more than one hour, but no no problems found.

Mostly this problem happened because of your Windows explorer.exe not working.

Solution 1:
Click Start Button. Type regedit in Search programs and files and press Enter button. It open Windows register editor.

Step 1
First backup your Windows registry using File -> Export.
Then navigate the following folders.
