alright, i was using my pismo last night, when i got the beachball. it didnt go away. so i restarted with the reset key combination. it came up with the folder/blinking question mark icon. ok, i restarted and went into the startup disk selector, nothing in there at all. then i reset the of and the pram, nothing. i removed the "right side" battery, and it came up. the problem is tht is been freezing like tht every so often. any ideas?
