I recently put together a new computer and installed Windows 7. I used two monitors on my old computer (XP), the regular monitor hooked up to the DVI port and my TV hooked up to the VGA port on my video card. I used the same card on my new machine at first, and recently replaced it with a newer Nvidia 460 card. I've had this same trouble on both cards, however. When I have both the monitor and tv hooked up, occasionally, the monitor (the primary display) will lose it's signal and power down, and the desktop will transfer over to the tv. After a few seconds, the monitor will power back on and the video will transfer back, with all the windows at the changed resolution of the tv (it's an older HD tv, and the hdmi port is busted on it). This *only* happens when I have the vga plugged in, though. It's never happened after I unplug the vga cord from the video card, and it never happened over the past few years when I've had the other computer. Any ideas? Thanks!
