Hello!
I wanted to upgrade my graphic card driver - so I've downloaded the new version from dell official web site. I got the error that it's not compatible.. I read somewhere that it's good to uninstall the previous driver and to install the new one. Yes, but after I uninstall the old driver, my windows doesn't recognize the video card. I can't see it at the device manager at all. I have only one 2nd generation Intel(R) CORE (TM) processor family PCI Express Controller - 0101, which isn't installed properly. I guess it's something from this optimus technology, but I have no idea how to fix it. My last idea is to try to repair the windows 7 system and if not - reinstall...
Thank you!
