1- Test the USB stick on a different PC if it does not work than it is defective or wrongly formatted, Try to reformat the drive using the HP USB formatter available on the web. 2- if it works on another PC, get the user guide for your motherboard: (if you don't have it download it from the manufacturers support web site) a- Check the BIOS settings, USB might be disabled b- If you are using Windows go to Control Panel/System/Device Manager ad verify that the Universal Serial Bus Controllers entry, and it's sub entries,is present and none of them have an error indication (exclamation mark), if this entry is not there than the conroller is not working. If the BIOS entries related to USB were correct then your motherborads USB part is failing. Try to reset the BIOS to it's factory defaults, if USB still won't work than the cheapest solution will be adding an OEM USB card which is available for 10 bucks over the internet. c- If the entries do have error indicator than erase them and using "Scan for hardware changes" option re-install them. If the error condition persist it might be a motherboard malfunction and again the cheapest solution will be adding an OEM USB card. In seldom cases the HW or SW drivers might get corrupted and the only solution here is to reload the HW drivers from the motherboard driver CD, and for SW, to re-install the OS. It seems harsh but my experience says 9 out of the 10 attempts to reload just the OS drivers do not succeed to recover.
