I have recently had the hard drive of my notebook reformatted and it is now impossible to connect my Xperia M C1905 to the notebook. I get the usb connection symbol on the top bar of the phone but it is not charging nor will pc companion recognise the phone. No problems connecting to my pc or this tablet before it was reformatted. Checked device connections and it shows that drivers are missing. Attempted to download drivers from Sony site but phone not recognised - Catcha 22!
Please explain in lay terms - how do I download motherboard drivers? Thank you for trying to help 
Well try visiting your motherboard manufacturors web site, find exact type of motherboard youre having and download chipset drivers. Or in case of notebook, find exact type you have and install/update chipset drivers from manufacturors website. And try to change USB port youre sticking USB cable in, sometimes it works
