Thanks strollin; i did a few re-installs and tried a few suggested instructions and nothing has worked,even Burned another Iso to a CD,well i'm back on Ubuntu 14.04LTS where i should never left,cause i had this issue before and since also gave a try to Ubuntu 15.10 beta,which was horrendous,i don't know how these people can use such bad beta Distro on day to day use,i understand Ubuntu testers have to use it to test beta versions, but if you are a normal user don't even try it cause you will be disappointed, always use LTS versions,
since i had made another CD with new Win 10 ISO so i went ahead gave it a try with win 10 in this machine and no avail,still not shut off,i think is a win 10 software issue for this lenovo desktop,i have another similar Lenovo Thinkcenter M series but it's M81,Hard drive and Win 10 installed on the M81 works on M71 but the shut down issue appears again.
