USB flash memory I know it on another computer does not open on my pc.
Answer: Open the device manager to make sure your device sees USB memory. Make sure that the USB drive is visible in the Disk drives section of the Device manager. Make sure that your device manager does not have an exclamation point after you have installed your computer in your USB memory. If you do not see any problems in the Device Manager, your USB memory may be infected; You need to clean the usb flash memory with Virus Removal software.
