PC randomly freezing with a buzzing sound. This usually lasts about 4 or 5 seconds and then my screens go blank and come back and then all is fine. A few times I have had to reboot the machine.
I have actually had this happen maybe 10 or 15 times over the last month or so and hadn't been able to pin down what was going on. I can't find any problems with my hardware or software. No malware or viruses. For me it usually happens while streaming from Netflix or Xfinity. Hadn't really tho
Do you have NVIDIA HD Audio Driver installed?
