My son Just bought me a new computer. It's a quad-core, and he says it has two graphics cards, which I think is the problem. He wanted me to use the hard drive that was already in it, but I didn't want to lose any of my stuff, and so I had him put my hard drive from my Gateway 825GM in it. Except that I can't get anything to work right. My Ethernet cable is working ok, but My resolution is stuck at 800X600, instead of 1920X1080. He's away for a while, And I don't want to bother him (Especially since I've been sending his phone into spasms with questions like this one. Does anyone know what I can do to fix this?
