Viaero HTC M7 not recognized by PC. Can only get to Recovery

I have a viaero HTC M7. I tried flashing a new rom to it. I was able to successfully but it did not have SU when it flashed. I tried a second time and that is when it went south. It now will not be recognized by the pc. I can get to fastboot and recovery. But as it can not be recognized by the pc I am no longer able to flash a new rom. I need help. Let me know what information you need. Thanks in advance.
