Hello my arduino pro micro is 5v model but i uploaded program with 3.3v 8MHz by my mistake
the power led is on but computer can't recognize anymore. how can i reset this?

You can mess around with trying to reset it at just the right time during the upload and you'll probably get it eventually.

I've done something like that a couple times and I found it easiest to just connect an ISP programmer (you can use a spare Arduino board as "Arduino as ISP" if you don't have a dedicated programmer) to do a Tools > Burn Bootloader on it.
