Minecraft will not open for me I've tried many troubleshooting issues I have a razerblade 2015. Sometimes it's the launcher or the world?

I've probably tried every way to fix minecraft, It used to play on my computer ( Razer Blade 2015) but now when I try to open the launcher after some trouble shooting either the launcher doesn't load or the minecraft world won't load but the launcher opened. It has been annoying me for months. I just wanna get down on some minecraft someone help. I have unstalled/reinstalled. I have messed with ram setting and resolution settings in the minecraft launcher. I have changed the version of minecraft hundred of times.
