I have an F1A75-V Pro Motherboard w/and Amd APU A8-3870K with HD Radeon 6550D graphics, also a ATi HD Radeon 6770 graphics card. Now I have been using Norton 360 v6 with the drivers for the 6770 card since I built this machine. Then suddenly I had to uninstall Norton and re-install it, now Norton doesn't work with the 6770 drivers, it won't even open up on my desktop?? Now the AMD Drivers that were installed with the motherboard and APU before I installed the 6770 which are Radeon HD 5700 works with Norton and the 6770 drivers won't. I have contacted Norton we went threw the uninstall and install until we decided that they will only work with 5700 drivers. Now windows will always try to update my graphics back to the 6770 which I would rather have but my Norton will not work with them no more. Any help with this would be greatly appreciated.
