I posted this before but no one will help me so I thought I'd revamp it... My PC had a problem, Dell XPS 420, something happened, thought it was the GPU but it only temporarily messed up the pc, now it seems the sound driver is uninstalled and every site I go to online has an error popping up saying the site is untrusted, even yahoo... I need help, I know I can solve the issues by restoring to factory default but if I do that then I have to go through installing all the programs and files and the like... what can I do? the system restore doesn't even work though it says it was successful...
