[QUOTE="bryphotoguy, post: 548543, member: 26695"] PRAM resets some sort of power management controller. If say something goes crazy and your video card stops receiving power, you could run into a situation like you're having. That's just an example.... If you don't have an OS, a folder icon with a question mark appears. It would still send a signal to the monitor. I don't know how else to really help you. [/QUOTE]
