Cisco Network Issue with switch

Haven't an odd issue with a switch. Its a Cisco Catalyst 3650 g switch with fiber upling. Flat VLAN 1, basic config nothing fancy. We started having a problem last weekend when the uplink gbic to another switch shut down. I replaced the gbic and the link came back however it seems shortly after we started having intermittent problems where a few of the ports started losing communication. The odd thing is that we could ping just a few addresses of servers off the switch but the rest we could not. This has since happened to 2 other ports now. We looked at STP and no ports are being blocked nor do I see any STP errors. If anyone has any thoughts on what this is or what else i can do to troubleshoot please let me know. Thanks.

If it a simple setup as you describe, do a factory reset maybe?

method depends on if its catOS or IOS

basically you need to clear the startup-config


Butit  sounds like a hardware problem.

Anything interesting from the "show log" command?

Thanks Pete... yeah that is what we are thinking at this point. Explored everything we can think of inthe way of STP and looking at the logs. We are going to cycle the switch this weekend (first time in over 2 years) and see if that helps. I will keep this thread updated with the results.
