G Raid w/TB Won't Work on PC

I have an older G Raid w/ TB 2 6 TB drive that I used with an TB2-to-TB3 adaptor on my a previous Thunderbolt-enabled PC. I recently upgraded to a new motherboard that is not Thunderbolt enabled. The new PC won’t recognize the G Raid. Is there anything that can be done to get the PC to recognize the drive?

Thanks in advance.

Uhm, if your new PC doesn’t have thunderbolt, the how are you even plugging it in?
