I thought I might of had to look at another keyboard. My Casio PX5s froze a couple days ago then it wouldn't boot-up after 7.5 years of no problems. Searching the internet found I needed to flash the bios as it has happened to others. Thankfully it worked. I really love the beast that the Casio PX5s is. If it does go, the first board I want to try is the Roland RD88 that came out last Summer. Seems like a good fit for my needs.
