When storm control is configured, a threshold is set, which is a set packet/byte count. You can see this with the command
show storm-control or show interface counters storm-control
If your PC exceeds that threshold it will err-disable the port. So, either your threshold is too low, or your PC could be sending lots of traffic to the switchport. Either way you need to know your environment to set the appropriate threshold. If it keeps err-disabling you will need to raise the configured threshold while making sure the PC is sending an appropriate amount of traffic.
If this is configured on a trunk (I would not recommend) you will likely need to increase the threshold more as it's taking traffic from all VLANs/devices downstream.
Hope that clears it up.
