I have an acer aspire es 15 and since I got the windows 10 update it wouldn’t turn on. I’ve turned it on today to see if the problem was temporary but when I turned it on the loading screen showed for literally .5 seconds and it went onto a black screen with a load of writing such as “intel UNDI, PXE-2.1 (build 083”) etc etc. I’ve never had a problem with this laptop before the update.
