CPU - Pentel Pentium G6420 @ 3.7GHz (according to device manager) I don’t know if this is relevant, but it lists that 4 times.
I did all of that…to the best of my ability…I may have left something enabled inadvertently. After doing all of that, I can now boot the computer fine. It hiccups a little on startup, but the 4th GPU is recognized. Everything is perfectly fine, until I start my miner. At that point, the PC freezes, and requires a manual reset. When it comes back up, the 4th GPU is no longer shown. The only way that I can get it to show back up is to turn the machine off, change PCIe slots, then reboot…same situation upon reboot.
I currently have 3 running for a little while, because the down time was maddening…
