I have a Samsung ATIV Book 8 with Windows 8.1 and it's been working beautifully for months now, but Device Manager is saying "Windows has stopped this device because it has reported problems. (Code 43)" in the Device Status window about my AMD Radeon HD 8700M Series driver. I've already checked and it says its up to date, but it's still not working. I've already tried the age old classic of turning off my laptop and back on; it helped speed it up, but didn't help the issue. My understanding of computers and coding and such is pretty rudimentary, so please respond with easy to follow steps. Thanks in advance!
