I have Lenovo AIO C200. Two days ago I upgraded the windows 7 OS to windows 8.1 After that when I start the computer I don't get any image, just black screen. As far as I could research it's the problem of compatibility of the BIOS and the microsoft update for the graphics card. But I was not able to find the files for the BIOS update for this PC on the Lenovo web page. My BIOS version is D9KT12CUS date: 06/08/10. I found a trick how to make the display work, but it's complicated and it's not the long term solution. Somebody can help me please.
