How do I troubleshoot Interface input errors on my Cisco 2651XM Router.

I have a cisco 2651XM Router, and have been recieving input errors on my FA0/0 port.  This is my port that connects to MY ISP.  Any ideas on how to troubleshoot this?  Below is my show interface ouput, for both interfaces on my router.  Thanks

I would start by replacing the cables and see if it makes a difference after clearing the counters.

Agree with jjmartineziii.

For additional monitoring, look at the free 30 day trial of Solarwinds Engineers Edition (www.solarwinds.com).  Gather some historical data on the errors and contact your ISP.

OK.  I will start by replacing cables.  I have contacted my ISP.  We both sent each other 10000 pings with a success rate of 100%.  It doesn't look to be losing packets.
