This may sound weird; but a few months ago I had a computer ( I returned it ) and whenever I plugged certain objects into the USB ports, it would INSTANTLY shut off like you said; if the object remained plugged in while Windows booted up it would instantly restart again; and it would go on and on. Eventually it told me the computer told me it was "protecting itself from a potentially harmful object" I never did figure out how to fix it; I bought a different USB wireless internet; is iTunes installed on your computer yet?

Do you have enough power going to your USB plugs? A power issue could be at hand.

Oh, well I returned that computer and it wasn't a power issue; it could be for him, not sure exactly what type of PSU he has; if it's a decent one, 350w should be enough. (assuming that his system specs are for the computer in question)

Actually, I just sold it to a friend of mine earlier today. It does have i-tunes on it. He's bringing it by tomorrow for me to look at, I'm just trying to get a head start on it tonight so I know what to look for. His old computer has a 4 port usb card that I'm going to try and install on it tomorrow, hope it helps.

My old iPaq, after years of working just fine, started frying my work PC's PSU seemingly randomly when I docked it. I must have burned through five of them before they told me I had to get a new iPaq.

So in my experience, USB connections can wreak havok on a PSU.

If your system only supports ver. USB 1.0 (possibly 1.1) and the device is ver 2 and not backwards compatable... who knows what it might do!
