i am using arduino 0021 and java 6

there was no problem until i got sudden 6 logs on my desktop at 2: 45 am and it's 5:15 am......in korea

and whenever i connect usb wire with or without my device, no power but a warning message that it's disabled so remove it,
after that i can't use my ports no respond at all
before the message i think i can use other devices though i only tried a usb mouse.

every problematic frames are from arduino/java/bin
so i reinstalled java 7, i changed the folder name arduino/java to other so as arduino use programfiles/java but can't even open it, i cleaned registry, reinstalled arduino

help me
