Around 15:30 GMT I noticed that the audio and network stopped working. I restarted my computer hoping it would work again but they both appear to be disabled after reboot. When I click the network icon on the bottom right I can click Troubleshoot. When it finishes running diagnostics, it gives me the option to Try repairs as an administrator. When I click this option the network starts working again although Windows Network Diagnostics say that the issues have not been fixed. Since the problem started this pops up every time I booted up. When I click the Audio icon, it opens a window detecting problems. It claims that the found problem was: Hardware changes might not have been detected. When I open Services, I attempted to start the Windows Audio service and got 'Error 1067: The process terminated unexpectedly'. Strangely it stopped the Windows Event Log service when I attempted this. I tried a System Restore but it failed and got the Error 0x80070005. When I boot up in Safe Mode with networking, the network is fine and I have no issues. Audio still has issues which I can't resolve because I can't start the Windows Audio Endpoint Builder. I have the assumption that a system file is missing but I'm not sure as to how that could happen. A person suggested to uninstall HP Support Assistant (which I could no longer open). This did not resolve my problems. Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question. It sounds like your drivers were updated without you realizing it. Try going to device manager and right clicking on your network device, click properties, Click the Driver Tab, and see if the 'Roll Back Driver' button is enabled. If it is click that. Check and see if that works. If it does make sure you manually run a Windows Update, and out of the list of updates available, find the network and sound drivers and right click on them and select hide update. 3 additional answers

Anonymous 2015-01-03T13:39:25+00:00 I rolled back the Realtek High Definition Audio driver and restarted my PC. Thankfully it has resolved both the network and audio issues. I'm a bit puzzled why it affected the network. Should I still update my drivers through the manufacturer's site (since there are no updates in Windows Update). Yes, update them from the manufacturers website to ensure you have the latest security updates for them, as driver software can and is often hacked, so it is important to keep your hardware drivers up to date from the manufacturer whenever possible. You can always try out Microsoft recommended versions as well, just be prepared to rollback if they don't work. However, the manufacturer updates are recommended over Microsoft even by Microsoft. Please be sure to mark the correct answer for this if it worked. Thanks, MicroComp's Unlimited 0 comments No comments I rolled back the Realtek High Definition Audio driver and restarted my PC.
