About a month ago I sent my computer(1) into BestBuy because i was using it one day and just out of no where the screen turned black. SO I shut it down and the screen came on but i was still black and I could see and move the mouse around. After BestBuy sent it back saying that they had fixed the problem. I hooked everything up and it worked for about 20 minutes before AGAIN the screen turned black and did the same thing. I thought there was something wrong with the screen(1) so I hooked it to my other computer(2) and it worked fine. Then I tried to hook the (1)computer (the one that turned black on my) to my (2)computer screen. But computer(1) had different ports. Computer(1) didn't have any BLUE ports only 2 WHITE ones(both ports had different holes in it). But on the cord with the BLUE ends the was a little BLACK adapter thing. It had a BLUE port on one end and a WHITE port in the other end. On computer(2) the was a WHITE and BLUE port but the WHITE port didn't have the right holes for computer(2) to plug into screen(1) So I went online and bought a new DVI adapter. I just got it and hooked up my computer(1). And the same thing happened. The screen came on but still black but responsive. A box popped up that said "DVI:Not Active AVG:Active ". and another box that said"Check Video Cable" Computer(1) is set to default on DVI but is on auto switch to AVG if needed. I'm really frustrated and confused because I can normally fix and problem on my computer? PLEASE HELP!!! P.s I know my computer is a Windows 8 but in not sure if its(32-bit) or (64-bit)
