Please help! I recently just purchased a new HP Pavilion labtop that came with Windows 8.1 and after a few days I received a pop up to update my HP Bios. I decided to update, after it finished updating almost everything stopped working... When I went to the Network and Sharing Center it said that the dependency service or group failed to start. I tried troubleshooting my audio systems and it said that hardware changes might not have been detected. I think that the motherboard is now corrupted but I'm not sure, the computer functions fine by itself but a lot of programs and services don't seem to work. I don't know what to do because I cannot connect to the internet and I tried doing everything that I can.
