My PS3 acted strangely yesterday and was wondering if this is considered a 'normal' system crash, or if I should be concerned. My system is a 80Gb unit with PS2 software backwards compatibility, which I bought used a couple of weeks ago. Anyway, I inserted Splinter Cell in the Blu-ray drive and while it was loading, I pressed the PS button to check my battery life, then returned to the game's loading screen. That's when I noticed that the screen was stuck on the 'loading' screen for what seemed like far too long. The system then beeped 4 times, and the console rebooted. Since rebooting, everything went back to normal, which leads me to believe that pressing the PS button while the game was loading was probably what made the system hang/crash. I guess the PS button is similar to the ctrl-ald-del command on a PC? Should I be concerned about this? I tried Googling the issue but the results mostly point to l337 speak and ******ed comments on the Playstation or Gamespot forums.
