Cisco 3750G all links reset

Question

I have a Cisco 3750G with routing enabled. Sometimes, I experience a situation: some clients computers are disconnected from the switch and then reconnected immediately. The whole things happened and ended within 5s. But it often happened, >5 times a day.
The log in switch shows:

I didn't see any problems here, just some interfaces are down and then become up again. This happened not only on this single computer, but on some other devices including a Apple Airport Exterem.
Anyone has any idea about this?
Thanks in advanced.

Answer 1

I'm pretty sure that the NIC and driver is not the problem.
Back in 2008, I had witnessed first-hand on how a brand new Intel GigabitEthernet NIC card reacts to legacy 3500XL switches.  No matter what IOS you've loaded on the switch the links will go down/up between 25 to 45 times per minute.  This will cause users very, very slow response.  The easiest way to fix this issue is to force the NIC card to negotiate to 100/Full. 
I am not saying to you have Intel NIC card but so far all suspects are on the table.  Your wired NIC card has not been ruled out. 
another Apple Airport Extreme which connected to this switch also experiencing this problem.
Hmmmm ... I'm reviewing the TDR result.  What kind of cable is this?  Is this a 1 metre cable?  Can you please change this?
