Inherited an Asus desktop supposedly loaded with Windows 10. Was reset before I got it. Upon switching on all I get is the circle of dots going round and round. After waiting ages and trying to alter a few things I thought I would try to do a fresh install of Windows 7. Went okay at start ie loading files messages etc then all I get is Windows starting message and nothing more. So appears whatever system is being used it gets so far then something just hangs it. I am thinking might be a bios problem but have not a clue as to ascertain if it is or not.
