what do you see under "show

what do you see under "show interface status" of the switch when the issue occurs?

do you see input/output rate on that interface when the issue occurs?

 

what is the spanning-tree state of that port?

 

when you say you get "ping transmit failed", are you getting that error when you try to ping the PC's IP address from the PC?

 

are you able to ping 127.0.0.1?

and, what does the PC's network connection say?
