Interface Errors in logs - 3750X

Question

Hi, 
When checking the logs on one of my switches, I see many entries for for a number of interfaces in the format of:
Mon Jun 02 14:45:12 2014: <187>312: *hostname*: Jun  2 13:47:32.575: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/5, changed state to down
Mon Jun 02 14:54:51 2014: <187>313: *hostname*: Jun  2 13:57:11.536: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/5, changed state to up.
It is a 24 port switch and the errors occur on at least 10 ports, there are no user complaints, but I just want the errors to stop being generated. Any ideas how to do this?
I have changed a couple of ports around, done a shutdown/no shutdown on each of the interfaces and even reset the switch. My next step is to change the cables, but because of the number of ports involved, I'm not sure that will really do anything.
Thanks,
Harv

Hi, Venperum
I am looking to format the nvram this evening. Can you verify some things? What do you mean when you say "format nvram"? The options I get for format are:
[format command output]
#format ?
flash1:  Filesystem to be formatted
flash:   Filesystem to be formatted
[End]
nvram is not listed. So I assume it cannot be formatted?
[Directory listing]
#dir ?
  /all             List all files
  /recursive       List files recursively
  all-filesystems  List files on all filesystems
  bs:              Directory or file name
  cns:             Directory or file name
  flash1:          Directory or file name
  flash:           Directory or file name
  null:            Directory or file name
  nvram:           Directory or file name
  system:          Directory or file name
  tar:             Directory or file name
  tmpsys:          Directory or file name
  xmodem:          Directory or file name
  ymodem:          Directory or file name
[End]
Looking at the above, I can format flash but not nvram. Are you saying to delete my startup-config from nvram and reload a couple times? If that does not work, the switch will need replacing?
There are also 5 files in nvram: Am I deleting them all (backing up beforehand, of course).
Thanks
