Recently the bluescreen appears when I start my laptop:
I start my laptop → It takes about 30-40 minutes to load → The bluescreen appears.
I always do the same on my laptop, I don't install anything and still it sometimes appears.
What can be the cause and how can I prevent it?
I also had this problem before. Just google WHEA-Incorrectable Error.
there you get help and solutions to fix the problem. Then there are also small tools that fix the damaged sectors in the library of the PC.
Can you get to the login screen or desktop?
No.
Then best with Acronis or similar. Software make a backup of your data and set it up again.
