Hi, I have just bought an iPod Nano 8GB. Downloaded the latest version of iTunes and installed. Then as soon as plugged the USB cable into the PC it shut down instantly. I had to wait a good 5 minutes when before it would boot back up again. I have tried the front and rear USB port... but to no avail I running Windows Vista and my PC spec is as follows: AMD Athlon X2 4600 Dual Core 2GB Corsair RAM 256MB GeForce 7600GS 320GB SATA II HDD MSI K8N Neo2 Platinum with Nvidia nForce 3 Ultra Chipset (motherboard) The USB ports are all 2.0 compatible. My PSU is 400W. I have 3 USB devices plugged in the rear and nothing in the front. Devices connected are: Keyboard Printer Scanner I am sort of guessing the iPod USB cable is causing a surge of some sort, but I might be wrong. Does anyone have any ideas as to what the problem might be... and how to fix it please? Many thanks, Gazza.
