Hi, I had the same problem, but mine started two days after uploading new music from my iPod. Pioneer said it was hardware but I had a hard time believing that. I didn't want to dismantle it and send it back so I thought I would poke around in the software. Somewhere in the beginning of the forums stickey has the download of the test mode software you need to boot up in tested. It took some digging and I can't remember where I found it but it's there. BE SURE TO MAKE A BACKUP of you system on a separate Sd card. Being a Mac guy I don't really understand Windows so I had to copy and paste files
