I'll be using my computer and suddenly the monitor says no video input, however I can still hear music playing or the game running in my speakers. The video input stays dead until I reboot the computer. It happens completely randomly, sometimes when I'm in a game, other times when I'm just browing the internet. The time interval is random too, it could happen 6 hours after I turn my pc, 1 hour, 30 minutes, 5 minutes. The temperatures of my GPU and CPU are fine and normal when I'm browing and when I'm gaming. I have done a clean wipe of the amd drivers and reinstalled it. I have dusted everything off. I have reseated the GPU, CPU and memory sticks multiple times. I have replaced the HDMI cord.

Specs:
OS: Win 10
GPU: AMD Raedon R9 280x
CPU: Intel i7 4790
RAM: 2 x 8Gb DDR3
PSU: EVGA Supernova 750w Bronze
HDD: Seagate 1tb
SSD: Samsung 223gb
 
Solution
Aside from trying a clean Windows setup, you need to test the card and/or power supply in another system or known good parts in yours to see where the issue is.
