Strange popup, laptop muting itself and randomly sleeping

This all started a few hours ago. My laptop just sleeps whilst I'm in the middle of using it. I thought at first it might be a graphics card problem because it seems to sleep only when I'm doing 3D modeling work in 3DS Max. It mutes itself randomly too, and now I just found this weird popup on the desktop:

I did thorough scans and made sure Malware Bytes and Windows defender are up to date. Any ideas would be greatly appreciated.
