So my laptop (Acer Aspire E15) with Intel Celeron Processor doesn't boot properly. When I press the start button the blue light turns on and it makes some sounds as if the computer will turn on but then it turns off. Then this is being repeated (2 - 7 times) and then the laptop turns really on. I don't know what caused the problem since I don't rememmber downloading any software before it occured. The laptop was bought about year ago with installed Windows 8. After the upgrade to Windows 10 the problem remained.
I wanted to startup in Safe mode but I'm not very sure how this could help me. So I would be glad if anybody can help me.

So thanks a lot for the answer @Ethan Z. I don't know how to make it accepted answer since I posted the question as unregistered user. Today as I tried to fix the problem it become even more evident that some connections inside the laptop are not working properly. Once it booted so as if every moment it would start up but it suddenly turned off. So thanks for the advice.
