You may be right but I have no idea what you mean when you say it's not detected.
So, you could copy files to your phone in TWRP today so your drivers and usb cable are good.
And your phone says "fastboot" on the screen?
Yes it shows up but win7 wont detect it I cant run any commands, this is why I been having so much problems. USB can see it as portable drive in twrp when mounted but other than that USB is not detect at all.
And I just tried to flash a different rom and it failed

error flashing zip '/sdcard/rom.zip
