In the device Manager, I see one adapter, a discrete video cardIn device manager do you see two display adapters?
Because your CPU has integrated graphics but I don't know if you can disable it in BIOS or you have to disable it into device manager.
If you see AMD video card, try to disable it
With 8GB RAM you should install a 64bit system, not a 32bit
If you can't disable AMD video card, the last thing you can try is to enable the internal graphic and remove the nVidia card and see what it does
