I have a gateway 310x. I tried to upgrade the memory and video card. I have ddr33 pc2700 ram and i bought a cheap 3d fuzion video card so i could try to display my pc image on to my tv. I cannot get an image at all now. The fans and everything turn on, motherboard powers on, there is also a red light on near the front usb section on the motherboard. Any ideas why it will not work. Please help…
