One more thing . Pinging the switch is abnormal . I am far from switch and normal ping should be less than ~10ms . But as you can see the ping goes high decussate

Looks like a hardware fault. This is not standard nor accepted behavior. I'd agree with Mr. Lock and test your cables. Beyond that, try re-loading the IOS image on the switch. If all of that fails, you might need to replace the switch.
