You can find the model or product number of the machine. This is how

model number


What OS do you have installed, Windows 8.1 or Windows 10.

Most likely it is a problem with the hard drive.

Try turning off the PC by holding the power button until complete shutdown. Press the power button and repeatedly keep hitting ESC until the startup menu appears.

Next press F2 to enter diagnostics. Try performing the short system test. See if it perfirms the hard drive test too.


Let me know,
