Exclamation USB device not recognized

Hello. i noticed that my computer(win 8.1) was giving a usb device not recognized error a few days ago. i didn't fix and eagerly updated to android 4.4.3, but forgot to disable freedom and now can't use google play services. i can fix that but the DAMN PHONE STILL ISN'T RECOGNIZABLE BY THE DAMN COMPUTER. i have tried multiple cables and installed win 8 dual boot but still got the same error. i also tried to reinstall drivers. but i think i didnot do it right.
both adb and fastboot are not working. if u could tell me a method to install a custom recovery without root and adb that would sove half my problems but still need help getting the computer to recognized the phone.

Normally this is a problem with charging block of the phone.

You have to root to flash recovery without a computer, towelroot works on 4.4.3. Once rooted you can use goomanager app to flash twrp recovery.
