BSOD DRIVER_POWER_STATE_FAILURE randomly after cold boot/sleep

For the past month I have been getting random BSOD's all with driver power state failure. They happen randomly, usually within the first 5-10 minutes of cold booting or waking my computer. Steps I have taken to attempt to fix the problem:

1. Reinstalled GPU drivers/ tried old drivers
2. Fresh installed Windows 1803, still happened, then fresh installed 1709
3. Disabled Fast Boot

None of these things fixed the issue, any help would be much appreciated at pinpointing the issue. Thanks
