Hello, this is my first time on these forums, so sorry if i do something wrong here (wrong section or not supposed to be using capitalizations whatever) i have a xfx geforce 8600 gt 512 mb video card, i installed it into my tower, but whenever i connect my monitor to it, it has no signal, i have the requirements for it, yet, it doesn't work, a friend told me it could be defective, but i'm just making sure here, and if it is defective, any way to fix it? and it doesn't need to be connected to anything other than the pci-e slot
