If you aren't getting beeps when turning it on, something is stopping the boot process. For sure get a PCI 2D card and keyboard in there as mentioned here and connect to a regular monitor so you can see if it's getting stopped in the BIOS (bad CMOS battery, etc.). While the game won't boot in this state, you can see if it's trying to (you'll see a screen about "transfering control to HYDRO.EXE"). If you can get it to that point, switch back to the 3D card and try to boot and see if it does/what beeps you get.
Also not sure a USB keyboard would work, probably need a PS2 one.
I do have a guide for getting any time-period (even into the late 2000s) PC to run the game, it's in this thread. It might still help you for setting up the original PC: https://forums.arcade-museum.com/th...how-to-run-on-a-modern-pc.513527/post-4617030
