Assuming the router boots OK at the moment and you have access to it see

for a free tftp server for windows see

first thing i would do would be to copy all the files form the router so you have these saved.
These files you know work and this is in case your new ios does not work with your current ram/flash.
If you have only one file in the flash this makes it much easier.
once you have set up your tftp server copy the file using the command copy tftp flash
and follow the prompts, it will erase the flash as soon as it can make a connection to the tftp server.
