Windows 10: I can't open up my Laptop

I have this problem where I ticked the Maximum Memory on msconfig and boot up on safe mode when I haven't restarted it say 4096 my max RAM is 4GB but when I restarted it say 0 so I unticked ONLY Safe Mode so when I restarted the Laptop can't log in the error code say Bad System Config info but when I tried the WinRE there's nothing there but option not the normal Recovery page and to top it all off I don't have the OS disk because it's pre-installed cuz it's a Laptop. And to add to that I forgot to opt out of Insider build.

Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd
