You can check your machine configuration, warranty and other information through your host number. If you can, it's true.
How to find the host number and model?

You can also go to the service station for testing. Or press F 1 to enter the BIOS, and check whether the host number in the BIOS is consistent with the number on the host shell.

Regarding the problem that your machine is stuck, I suggest you try the following:
Press shift+F8 to enter safe mode, and then enable clean startup troubleshooting:
1. Touch the right side of the screen and click Search. Or, if you use the mouse, point to the lower right corner of the screen and click Search.
2. Type msconfig in the search box and click or click msconfig.
3. In the System Configuration dialog box, click or click to select the Hide all Microsoft services check box, and then click or click the Disable all services tab.
4. Open Task Manager, select the project, and then click Disable.
5. Close the Task Manager.
On the Startup tab of the System Configuration dialog box, click or click OK, and then restart the computer.
