Today I was connected to the external Alienware Graphics Amplifier, when suddenly the screen went black and the fans on the external graphics card revved to full blast. I had to disconnect the cable and hard power down the laptop, and when it came back up, the computer was no longer detecting the internal Realtek Audio chip. I attempted to reinstall drivers, and when that didn't work, I performed a fresh install of the OS from Windows Installation Media, including formatting the boot drive and then installing Windows 10. I've installed the drivers, reset the CMOS, and inspected the BIOS for any settings relating to the sound chip but can find none.
Are there any tips on resolving this issue before I reach out to warranty support? I've had this computer less than a week and would like to try to get it resolved without waiting for someone to come out and replace the motherboard.
