My laptop has had problems being very very slow in the past. And I got the same pop up about memory and how I was low. I ignored it of course and at a point Windows became too awful to use I tried to factory restart my computer (from setting) it got to about 7% before I was told their was an error. I left it alone for the night but coming back to it and trying to start it up I'm met with the Acer screen than a black screen. And it keeps repeating. I can't get into any of the f keys and when I get into f10 I'm met with "choose your language keyboard" and then the repeating of the black screen starts again. I don't know barely anything about laptops so this is a really hard time for me. I own an Acer Aspire e5-521-23kh and I'd appreciate any help given to me!! (I truly don't know anything about computers to bare with me.)
