Hey everyone! I recently upgraded my PC with a new Intel 14th gen i7-14700KF processor, but I had to update my BIOS on my ASUS TUF GAMING Z690-PLUS WIFI D4 motherboard to make it compatible. After some troubleshooting, I managed to get the BIOS to recognize the new processor. However, during the first startup, I fiddled with a few BIOS settings and encountered a 'fatal error, computer case is open' message. I suspect I accidentally changed the chassis intrusion detection setting. To fix it, I removed the circular battery to reset the BIOS, put my old processor back in, waited a bit, then reassembled everything. Now, when I power it on, the motherboard lights up, but nothing happens when I try to turn it on—no fans or anything. Did I brick my motherboard, or is there something else I can try? Should I be concerned about static discharge, or could this merely be an issue with the BIOS settings? Any advice would be greatly appreciated!

It sounds like you're in a bit of a bind! From what you're describing, it seems like your motherboard isn't completely bricked, especially since the lights are coming on. The fact that you can't get any response when you hit the power button is a bit concerning, but it could just be a setting or a power connection issue. Make sure all your power cables are secure, especially the 24-pin and the CPU power cable. Sometimes reseating these can make a difference. Also, try removing all components except for the CPU and one stick of RAM. If it still doesn't start, you might be looking at a motherboard issue, but don't give up hope just yet!
Don't panic just yet. The chassis intrusion setting could definitely be causing the boot issue, so double-check that everything is plugged in correctly. If you haven’t already, try clearing the CMOS again after ensuring the system is completely powered down. If you have access to a different PSU, sometimes that can make a difference too. It's good to rule out all possibilities before assuming the motherboard is dead.
Definitely don't rule out the PSU. Sometimes older ones can drop power and cause strange behavior. If you have access to another, try testing it!
I had a similar issue and it turned out to be a loose connection! Just re-check all connections and maybe try booting with just the essentials. It might save you from buying a new board!
