Hello, I need to check my HDD health (Deffragler says it has problems but chkdsk not

), so I've seen on Acer web site that I need "ACER care center". I look for the ACER tools already installed - Acer recovery management, ID card, Live updater - but "care center" was not here (not here anymore ?). I've also noticed that liveUpdater wasn't updating anything : nothing update as far as it remembers although there is new 2017 drivers on website...
So I download care center W10 version, install it on system drive, check it was really here (OK). I click on the tool, windows appear to ask me if I'm OK for change (OK), a green window appears quickly and... nothing more ! In task manager, "ACCstd" processus run in backward but nothing on screen.
My computer : E1-570, bought in december 2015 with W8. All windows update succeed , even W10 update 1709 (with some difficulties but at least I have won !). No hardware change, I just make partitions to separate pagefile, software and data, for a very fast starting.
My questions : what's happened ? what can I do to run in anyway the "PC checkup" (included or not in acer care center)
