I just swapped my computer case and power supply unit (PSU), but now my PC won't show anything on the display. I've already tried reseating the RAM, the CMOS battery, and I've also tested each RAM stick individually. Plus, I've reseated both the GPU and CPU, but it's still not working. I'm looking for any advice or solutions to get it displaying again!

It sounds like a cable connection issue. Make sure you double-check all the cables are securely connected. Sometimes, even if they look plugged in, they might not be making a solid connection. Give it another look!
Did you switch the PSU cables? If you used the new cables that came with your new PSU, that's great. Otherwise, it might be worth checking to ensure everything is connected correctly.
If your motherboard is a HP ms-7860, make sure to check if there are any jumper settings you need to adjust. Sometimes, a simple tweak can help. Let me know if you need more details!

I used the new cables since it's non-modular, so I think that should be fine. Thanks for the tip!
