This is a bit of nastiness! You have a switch that refuses to boot. When you watch what's happening on the console you see errors like this:

 Error loading "flash:c3750-k9-mz.122-44.se2.bin"
 
 Interrupt within 5 seconds to abort boot process.
 Boot process failed...
 
 switch:

You have a corrupt IOS image! To recover you will need Microsoft Windows HyperTerminal to perform an xmodem transfer of a new IOS image to the switch (obviously you can use other terminal emulators etc, but you'll get no help from me :-). This method has been tested with a Cisco 3750G. You can see more specific info for different switch models here.

1. Connect to the switch with HyperTerminal with these the settings:

 Baud: 9600
 Data bits: 8
 Parity: None
 Stop bits: 1
 Flow control: None

2. If the switch is not already at the switch: prompt, remove the power cord. Hold down the MODE button on the front of the switch and re-insert the power cord.
