Most likely this is an overheating situation. Itunes, RealPlayer, Windows Media player, etc. require a lot of processing power to decompress and decode music files, which can cause the system to get hot.
If your CPU is running at over 60 degrees you might be at risk of burning it out. Some systems shut down automatically when the temperature reaches an unsafe level. If you determine that overheating is not the problem, the most likely suspect is bad memory

What is the CPU temperature?

Be sure to run it for at least 6 hours, preferably more. Try running it overnight.
