Miner Stopped Working - Need Help

After attempting to change clock speeds using commands in the .bat of claymore dual miner, my system has been acting weird and not working properly. It will begin to work, but soon after the screen flashed black a few times and then Windows restarts. Also, no AMD GPUs will show up after it does that. I have reinstalled drivers and Windows multiple times and the problem persists.

Any advice? What could have happened?

System:
Windows 10 64-bit
Celeron G1840
Gigabyte GA-Z97X-Gaming 7
EVGA 850 B2
2x RX 480 4GB
2x RX 470 4GB
