Working computer no longer posts.

Hopefully we can figure this out here so I don’t have to drop $1000 on a new CPU and mobo. Not exactly sure what the issue is. I just changed cases like a week ago. I don’t think it’s a leak in my water cooling loop that caused it. My motherboard has been a little wonky lately I had to enter the bios every time to select my boot drive since it wouldn’t save. This computer has been working for years and just decided last night to stop working. Most importantly last night my computer wasn’t shutting off after I hit shut down so I just held the power button until it shut off because I’m an ape. Won’t even post to Bios any suggestions? Did I brick my mobo? Could my 12 year old power supply be the issue??? Any thoughts would be awesome to hear.

Possibly, typically a good setup like yours requires at least 500 watts. But when you said its 12 years old, then that is probably the problem. Too old of tech these days can't keep up because of the economic growth.
