I have a strange problem with my Dell Latitude e6530.

Periodical it is unable to boot completely. The post does run, the Windows 10 logo appears, then blank screen.

If I then hold the power button until it shuts down, and start it immediately afterwards, the PC startup normally.

The problem appear first time just after I updated to latest bios version from the Dell homepage.

Until now I have tried the following:

1. Re-installed Windows
2. Reset Bios to default settings
3. Removed battery and turned on without it
4. hold Fn and run diagnostics (no problems found)
5. Updated all drivers to latest

Any suggestions on how to solve this ?
