Windows 10 HOME X64 - System Hangs immediatelly after login......

...... but not goes in crash like BSOD or similar but simply i can continue to see pointer on mouse (and i can move it) but i see the blue icon spin and nothing append, every key it's ignored also like CTRL-ALT-CANC etc etc.

Sometime i can reach the desktop (and immediatelly hang) but sometime it's be hang on "Welcome" message....

Meanwhile it's a HP Mini-Desktop series... whit Windows 10 Home x64 a i5 processor and 8GB of RAM......... how i can check for try to restore this pc ?

I have also another pc (mine from where I'm writing of course :)) and if i need to pick file or programs in internet suggest me....... for example if i can create a setup for make a dirty installation over it.....

Thanks in advange for every suggestion...... and sorry my BAD english.....

I don't know because it's not a my daily pc...... it's a my friends pc and it's ask to me a little supports :)
I don't thinks it's a new hardware installation because this my friends it's not skilled about this :) I thinks possibly windows trouble or somethigs similar....

Meanwhile yestarday night i have created a installation pendrive.......... i have try to use it for restore but never append. Right now i have directly re-installed windows used this pendrive and selected the same partition from wizard (and obtain a windows.old folder) and apparently all it's back to work.
I stay eventually to copyed right now all possibly old file to this newest installation....... at this point i thinks it's the best solution i can choose.
If i obtain some problems be back here to inform you :)
meanwhile thank you for your interest...
