I just bought a new Gigabyte M61PME-S2P and AMD Athlon X2 250. I set everything up with XP Pro on a Viewsonic Graphics Series G810. Everything was fine. I unplugged everything and set the PC up with it's own monitor, a Viewsonic Viewpanel VG150. The computer would not power on at all. through removing each component and retrying the power button I came down to the monitor as the problem. I tried keeping the monitor unplugged, starting the PC and then hooking up the monitor. The mouse and Keyboard would not work. I tried starting it with the G810, and then switching to the VG150, and the mouse and Keyboard would die as soon as the VG150 was plugged in. Any clues?
