I recently bought a lightly used gaming PC from a friend's defunct cafe and I'm struggling to boot into any operating system. Here are the specs: MSI B550A Pro motherboard, Ryzen 7 5800X3D, Kingston Beast DDR4 RAM, and an Asus RTX 4060ti graphics card. I don't have any installed storage yet, as I'm planning to use Linux. I've got several SSDs, one of which has Linux Mint that worked fine on my old PC. I also have a thumb drive with Ventoy and multiple distros like Ubuntu and Pop!_OS.
The issue is that the PC successfully goes through POST, and I can get into BIOS. However, when I try to boot from the SSD with Mint or any other OS via the Ventoy flash drive, I get no display. I've already disabled secure boot since I learned that the Nvidia card needs special drivers. I've checked all the cable connections for the GPU and display, and they're fine, as I can see the BIOS. Whenever I connect a storage device, I lose display, and I can't access BIOS anymore by pressing delete. I'm at my wit's end trying to figure out what's going wrong. Any help would be appreciated!

Sounds like it could be an issue with how the MSI motherboard is handling UEFI/Legacy boot with Ventoy. I recommend trying to clear the BIOS as a first step. If that doesn’t work, see if you can update the BIOS once you can access it with a USB drive connected. As for OS, CachyOS might be a good candidate as it comes with built-in Nvidia drivers, so maybe give that a try if you can get everything stable first!
You might want to check if the CMOS battery needs replacing, as a dead battery can cause issues like this. If that's not the problem and all your cables are properly connected, consider updating the BIOS. Just a heads up though, that's a sensitive operation, so you might want to be careful with that. Also, have you checked the BIOS date? If it's pretty old, an update could help.
I checked the BIOS date and it's correct. I was thinking about resetting the CMOS, but it’s hard to access under the graphics card. I can update the BIOS fairly easily, but I’d prefer to avoid it if possible since I don't have a working PC to download the update.
Make sure your monitor is connected to the Nvidia card and not the onboard graphics. Double-check that it's set to display port settings too; sometimes that can cause issues. Also, what’s your monitor model?
The monitor is an ASUS TUF Gaming VG27A and it's definitely plugged into the display port on the GPU.

I was actually leaning towards CachyOS because of compatibility. The problem is I don’t have a PC to download anything or create an installer right now; I'm pretty much stuck borrowing a friend's computer.
