hey i have a really annoying problem that i think started around a week ago. every time i plug and kind of USB flash drive the mac osx 10.5.6 gives me the "you need to restart your computer. hold down the power button for several second or press the restart button" message. i talked to apple and they told me to restart my PRAM and NVRAM which i did and did not help me at all. i really need a solution please please help me Thanks..
