Whenever i turn my computer on everything turns on except for my monitor. The fans are all spinning, the cd/dvd drives turn on and so does the hard drive. The monitor is connected to a PCI video adapter and the LED in front blinks green once when i turn the computer on and then stays that amber color so i dont know what the computer is doing. The motherboard, CPU, Memory, and Hard DRive are all brand new. I still need to install an OS but if the screen doesnt turn on i obviously cant do that. I cant figure out the problem because the monitor worked fine on my old computer.
