I just finished building my computer and when I was going to install Windows 7 on it, I encountered a problem. After a couple minutes of me leaving it alone, my computer stops sending signals to my monitor. The fans are still spinning, the lights are on, but the monitor is pitch black.
Now I could dismiss this as the how the computer sometimes acts during installation of the OS, but this also happens when I leave the machine alone for a few minutes in the language selection section. I doubt that's supposed to happen.
Please help, thank you very much. Below is the build that I have, plus an optical drive I can't find, and a GPU from my old computer (Sapphire's Radeon HD 5770), also that I can't find in pcpartpicker.
