I'm having a serious issue trying to install Windows on an older PC that used to work perfectly. This machine was my go-to for gaming and work until I swapped its case for a new GPU I got for another computer. After the swap, every USB port stopped working, and the hard drive only boots occasionally. I left it for a while, but now I'm trying to revive it. I managed to get to the BIOS using a PS/2 keyboard, which was a relief. I planned to install an SSD to make it my main PC, but despite creating a bootable USB, the system keeps claiming that no operating system is detected. I've been troubleshooting for hours and feel completely stumped. My components (Xeon X3470, Gigabyte GA-H22M-S2, 1050 Ti) are outdated, and I haven't found anyone with a similar issue online. I'm not looking to replace major parts or burn a DVD; I'm determined to make it work despite being on a tight budget. Any advice on how to get this old machine running would be greatly appreciated!

Have you considered the possibility that there might be a short somewhere, perhaps with the motherboard touching the case? It’s worth examining, especially since USBs are acting funny after the case swap.
Make sure to reset your USB settings in the BIOS. Set USB ports to always powered on and prioritize the bootable drive as your first option. If you have access to a USB tester, that could help you troubleshoot if there's an issue with multiple ports too. Good luck!
It sounds like you might not have the case button cables connected correctly to the motherboard or that the USB cable is oriented wrong. It might help to double-check those connections, just in case!
I’ll definitely check the button cables! I’ve plugged my USB devices directly into the back of the motherboard, so hopefully that’s fine.

I actually set everything up on a cardboard box to rule out that possibility, but the USB ports still wouldn’t work. It's infuriating!
