Excuse me for my bad English, I'm using Google translator...
I have a
Samsung NP355C5V-A01UB Notebook with an A8-4500 APU with AMD Radeon HD 7640G.
My operating system was updated to Win 10 1903 and now I do not recognize the video card. I tried updating the drivers, the BIOS and even returned to Win 8.1 but it was not solved ... If I try to place a previous driver it says error 43 ... and if I update the driver, the error does not come out, but the board does not work .
Please, I appreciate any kind of help.
