ACT Led lights Off and Cause the whole network DOWN

[wilfredodedase]

Hi Everyone !

Sorry to ask but I am new to Cisco.

I recently had an issue regarding on our router that ACT and SYS LED turn off and cause the network down. Can someone explain to me the cause and solution to resolve this issue ? 

Cause after it happen I just restart the router and works and after I search the problem stated " No packet transfers are occurring" "The router CPU is not operating."

Please I really need you help

Regards

This description is not sufficient other than it's telling me the router has crashed.  Someone needs to console into the router and do initial troubleshooting.
