I have a Nvidia Ge Force 8300 GS on my Dell Inspiron 531 computer (with Vista service pack 1) and experienced a major problem with the display-everything appears much too big like it would in the safe mode, with vertical yellow lines across the monitor,or if I try to start my computer after a few days the picture completely coved with colourful lines and squares. The device manager indicates there is a problem with my graphic card(shown with a yellow triangle), the diagnostic program tells me that the device has a configuration problem that prevents it from working properly the device Nividia Geforce 8300 is reporting ‘’tv_configMgrErr43’’ . I have tired searching for solutions on the internet I understand, my computer has a problem to update nvidia. I went to Nvidia website and directly downloaded a driver for videocard but it didn’t work.I have tried again and again,still there is a yellow triangle and distorted picture, the new driver is not accepted by Microsoft system. Whilst looking for help I found many others had written on help forums experiencing the same problem regarding a Nvidia Ge Force 8300. Unfortunately there was nobody who provided a solution,in my opinion there must be some problem with this product which appears after Windows automatic system updates,what to do now? replacement?
