packet drops and causing slow network

We are getting some packet drops on our some 2960 switchs.

sh int f0/27 | inc drops|bits

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 10297

5 minute input rate 0 bits/sec, 0 packets/sec

5 minute output rate 6000 bits/sec, 3 packets/sec

And users are complaining about slow network and taking long to open any network drives.

It’s a (C2960-HBOOT-M) Version 12.2(46r)SE2 lanbasek9-mz.122-55.SE3.bin

But there is not much traffic going trough and we still getting drops

FastEthernet0/27 is up, line protocol is up (connected)

Hardware is Fast Ethernet, address is

Encapsulation ARPA, loopback not set

Keepalive set (10 sec)

input flow-control is off, output flow-control is unsupported

sh int f0/27 counters errors

Port      Align-Err    FCS-Err  Xmit-Err    Rcv-Err UnderSize OutDiscards

Fa0/27            0          0                  0              0        0                    10297

so we just make this port a access port and remove the phone to see if we still getting drops
