I recently ran into a problem with my laptop. Upon start up, once i reached my usual tab, my screen starts switching between the normal screen and a black screen. Its switching like every second which makes my laptop unusable. I searched for the problem on the internet and it said, it is probably caused by a windows 10 update. After trying numerous of the given fixes i still didnt work it out. I hope someone could help me out here and might know how to fix this. Since i am not an expert with pc's and laptops i have no clue what to do. So if anyone got any solutions for this problem, please share them with me.

That would tell you if it was a software issue or a hardware issue. If it was a windows update you can revert that update or restore your computer.
