Then just check your xorg log, dmesg and the journal for coincidental messages.
Also try to get mutter out of the way, eg. with an openbox session or so.

thanks with an openbox session it works,but can i get cinnamon to run without mutter?

No.
Check the logs on what happens (likely HW or randr related) when/during you trigger the freeze.
