Run Malwarebytes… then, revisit the question. Does it make no difference if it isn't chkdsk /r /f?
Install & run CCleaner
and
Do this:
> cmd, Run as Admin
type or paste in %SystemRoot%\System32\Cmd.exe /c Cleanmgr
/sageset:65535 & Cleanmgr /sagerun:65535 , hit Enter
Hit OK on the window that appears, after checking all boxes the 1st time this is run...they stay checked when it is run subsequent times
Cheers,
Drew
