Cisco 3550 Packet loss and connectivity issue

I have a Cisco 3550 48 port switch which as begun to experience packet loss leading to connectivity issues to my network in the last 3 days. The problem comes and goes and has varing levels of severity.  I have booted the switch botted the media converters on both ends of the fiber connection.  I can generally see in to this switch and its VLAN, but dependant upon the severity of the packet loss cannot always see back home.   Looking for suggestions on how to troubleshoot this problem.

Are you sure the issue is the CIsco3550?
What is the end to end connectivity look like (traceroutes, pathping, etc)
Issue could be related to the GBIC Slot, the GBIC itself, or the fiber cables (Maybe try cleaning the cables).


On the 3550:
Are there any errors on any of the interfaces?
show int fast1/1
show log
show proc cpu (even checking the history will help)
Check duplex and speed settings
