OK so i dont know what happened to my Raspberry Pi B+ but whenever i put in my sd card with noobs the green and red lights stay on. When i searched online it said to find out if my Raspberry Pi is dead i had to plug it into my pc with a usb cable and if the pc found it the Pi was alive, but my pc didnt find the Pi so i dont know what to do so please give me some suggestions or if they dont work i will have to see if i can return it. And when i put the sd card in my other Pi it booted up properly.
