Ok, This code 10 thing started ever since I reinstalled Windows XP. I've got that sandisk player and when I plug it in it says '' Problem occured during hardware installation etc....'' So, I tried the whole uninstalling reinstalling junk with the ''usb mass storage device'' and restarting and the exclamation mark still came up. Tried updating. Plugged it in directly to the usb with the designated 2.0 usb. And i checked all updates.And I don't really understand anything else anyone posted concerning bios, the master thing, and stuff about the motherboard. I'm obviously new at this. Please help With anything you can pull from under your sleeves. I will forever be sad until then.
