    Ah, no disaster plan... a bit like the British Library, taken down by Russian hackers and costing millions to recover..

    I do think some bad sectors is most likely it. Still hoping for the quick easy fix though

    Thanks for the event viewer link, that will come in handy too
    Bad sectors, Bad clusters etc is a warning that the drive is failing.
    How many bad sectors it has?

    Run HD sentinel. It's free to try.

    I have taken notes of all the software suggested (and will in case there is more). I won't have access to the PC for the next two weeks but I will update the thread when I'll have news about my poor little machine. Thanks again :)

    Maybe I'll also try to see what files are being accessed when the HDD response times go out of control (if any in particular), I think I used ProcMon a long time ago for that. I guess it can't make things worse anyway

    I was trying to avoid Procmon - especially as you say you've seen the problem in Safe Mode.

    Easier to prove it is or isn't the disk.

    Oh, alright then, will keep that in mind. It might also become useless when the disk is so slow I fear

    So here I am. Windows build is 19045.3803

    I have found corrupt files which I cannot delete (error 0x80070570). Before doing anything else I'd really like to delete these files, I have already tried deleting the folder with admin CMD in safe mode but it always says it can't delete the corrupted files

    Is there anything I can do to force delete the corrupted files? What I've found online so far is stuff like this How to Delete a Corrupted File Windows 10? Solved Here - EaseUS

    Thanks

    Have you yet run a disk check - Hard Disk Sentinel or Crystal Diskinfo?

    Portable versions of these are available- could run from a flash drive.

    If your drive is failing you
    a. should stop using it.
    b. recover anything that is not backed up- if you can.

    If your drive is failing trying to delete files etc becomes irrelevant.

    I will definitely run hard disk sentinel, unfortunately it's my workplace PC and I have not a lot of flexibility and today it was not possible. I will update the thread about that too

    Since it could be an easy step I'm hoping that deleting or fixing the corrupted files will help the disk to not freak out

    The windows error checking utility for the drive says "we found errors on this drive. to avoid data loss, repair this drive now" which would be pretty convenient, though I'd like to know more about it before running the repair the next time I have the opportunity

    Deleting the files isn't relevant. It's not the cause of the problem. It's the consequence.

    I already posted a link for Crystal diask info and HD Sentinel.

    Open a CMD window as administrator and type:
    chkdsk c: /f
    It will say your disk is in use and ask if you want to schedule to next start = yes
    Restart
