Without warning, my computer suddenly stopped recognizing that I have an AverMedia M791 TV Tuner card plugged into my PCIe slot. I am able to install the device in safe mode, and use the updated driver from AverMedia, but when I try to boot normally I get the BSOD. I've reseated the card, to no avail. This issue occurred just after the last automatic update. In addition, I no longer see Windows loading on my computer screen (although I can see it via the HDMI connection to my flatscreen TV). Any suggestions?
