Hi all, After a long wrestle, I've just installed a Radeon X1650 Pro into my old Compaq Presario 6000. It was working very well through a couple of reboots, but now I get Windows opening without any video output. The mouse cursor is visible and movable, and all the audio cues are going off -- it's strictly a display issue. I've tried working in BIOS to isolate the problem, but the onboard graphics don't seem to be interfering with the new card (and they didn't with the previous 128 MB model, either). I had a system crash while playing Civ 4 and came back at low res right before the problem started to occur, so I've tried bringing up the aperture to 256 -- still nothing. Any advice? I've got a lot of work to do today, and ATI tech support isn't open on weekends!
