[Q] Need help

Hi, i recently watched a video on how to flash an unofficial CM12 for the Samsung Galaxy S3, so i downloaded the files on the internal storage instead of the sd card (im dumb i know) and then i did a factory reset and system, so know when i boot up my phone it's stuck on the samsung logo. I did some research and it seems to be soft bricked. So i found out that if i put the files on the sd card i can flash them, but the thing is when i connect the device i just hear the beeping sound but the phone doesn't actually show up in windows so i cant transfer the files to the sd card. My ADB drivers are updated, i have samsung kies installed but i don't know what to do. I'm using windows 8.1. Please help, any help is aprecciated. :o
