I was using my copm a few hoursn ago. Im using a P4 2.8C processor on an ECS PT800 CE motherboard with 1 G RAM with my old 128 mb NVidia MX 4000 video card, when suddenly the display disappears and my comp beeps (long beep that dont stop until i turned my comp off). I notices that my comp still running and the activity led is still blinking. I restarted my comp and my my turned on but theres seems to be no cpu and monitor connection. Is this a video card problem? I just want to be sure before i buy a new one. Thanks
