Hi, Sorry, its a very basic question. Could you please tell me what motherboard I have? I had purchased this comp some years ago from HP-Compaq. I tried running everest and am attaching two screenshots below. In one it says 845G and in other it says 845GEV. 1)What motherboard do I have after all? 2)Can someone please tell me where can i read more about all the information shown in Everest? I'm a complete beginner in hardware. 3)Is it possible for me to add a graphics card to this motherboard? (no matter how old) Thanks.
