I have a PNY Optima Pro Attache 2G flash drive, and when I plug it into my PC with Vista Home Premium, nothing happens. When I go to My Computer, its icon shows up, but when I try to open it or just click on it, Vista crashes ("not responding"). This drive is supposed to be compatible with Vista and not require you to install drivers, so why is it crashing the system? I know nothing about computers, so any help in layman's terms would be much appreciated. Thanks.
