If this is a fast ethernet interface, what are the
speed/duplex settings on the router port and the
device its connecting to? You shouldn't see collisions
at 100full unless theres a equipment problem. If you
have mis-configured speed/duplex or auto-negoation
mismatchs then you could see collisions, late
collisions, alignment errors, etc.
As for this happening at 2-3pm, anything happening in
your network at that time (broadcast storm, network
backup, etc)? I'd do a sniffer trace and see what that
reveals.
As for DEC21140, thats the chipset used on the
Ethernet interface.
