its worked fine in the past so its not the hardware
i could really use some help on what to do

Mhm, you have similar issue as this guy in other thread. Try comparing his PC specs to your own and see if you got anything in common.

For example if you both have same graphics card then most likely something went wrong with drivers and you should update them. Or wait for new driver updates.
