Moto G XT1032 Black screen, can't reset

I was playing a game I've been playing for at least one week, when my screen suddenly went black. Pressing power wouldn't help. I had this happened once and did the "press power+vol down for 10 seconds" to reset the device, but now it didn't work. I've been looking around to see what to do, and nothing is working.

Pressing power for 120 seconds (as motorola's site suggests) didn't work.
I tried adb reboot but I got "device not found."

Code:

---

fastboot devices

---

showed it, though, so...
I tried

Code:

---

fastboot reboot

---

and I got "rebooting... finished." But nothing happened on the phone.
So I tried

Code:

---

fastboot reboot-bootloader

---

and now it's "waiting for device" and

Code:

---

fastboot devices

---

reports nothing.

When I press the power button for 10-15 seconds I get a vibration, but that's about it. If I press it along with vol down I get nothing, but windows reports it as an unknown device when the 10 seconds pass (as if it restarted).

Any help would be greatly appreciated as I don't have any backup device or anything u_u"
