I hope it's correct board for post like that.
First post, what a way to start! There we go:
Whenever I leave my laptop be for a few minutes, it freezes. After minute, two, ten it unfreezes and works as nothing happened. Happens mostly when I turn on music in foobar2000 and leave it be (e.g. while I'm learning) or when going to toilet (so it's completly idle). Computer stops responding to anything I do. For few seconds I can switch between open tabs (like apps or browser tabs) but can't open new ones (browser tabs simply end in endless load). It doesn't happen when I'm actively using computer (like playing games/browsing internet/chatting).
I have no idea what's wrong. I did use command sfc /scannow, it has shown some errors, mostly with .Ink files. I cleared the log from "correctly verified" comments. Only errors are in it now. While browsing net I've found that I should use "dism" command. Did it with ScanHealth and RestoreHealth. Sadly, RestoreHealth asks for source. While providing (created .iso with MediaCreationTool) source it tells me... it needs source. Seems like install.wim is missing. Sadly, couldn't download the techbench one (trying to download simply results in error).
I'm kinda stuck now as clean reinstall is impossible for me right now (end of University year, I have to do some assignments, also, not so good internet connection, so can't download everything I'd need).
