Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
what is the make and model of the computer?
is it an upgrade from windows 7 to windows 10?
Try to unplug anything you have got connected to the comupter on the usb port apart from the keyboard and the mouse.Unplug power cable and then press and hold down the power button for 30 seconds without connecting the power cord.
Once done plug in the power cord and turn on the computer, do not connect any thing apart from the keyboard and mouse.let it boot up and let me know on which screen it freezes.
on what screen does it freezes?
