I'm new here, therefore I would like to introduce myself. My name is Peter and I am from the Netherlands. I have been having some problems with my Lenovo laptop, with that I want to ask you for some help.
I have Windows 10. Since a day I have been having the same problem everytime I start up the laptop: right after starting up, a screen pops up for about half a second and then automatically closes. It is too short to see what kind of screen it is or to make a screenshot (trust me, I have tried). Does anybody recognize this problem? I don't believe it is the CMD screen as it is a really small screen.
I am afraid it is a virus or some malware, but Windows defender, Malwarebytes and Panda free anti-virus do not seem to identify a threat.
