I have 2 computer both running Vista. One has the 8600GT card. Last night I was getting no display, monitor said no signal. I plugged it into the Mobo VGA and had display. While I had display I updated the driver for the card. In hardware devices it said the display card was functioning, I updated the driver anyway and got the message it was successful and needed to reboot. I shut it down as it was late and booted this morning. I still had no display from the card and now I have no display when connected to the Mobo.
I tried on a different monitor, no change.
I reseated the graphics card, no change.
I reset the bios by removing the CMOS battery for 5 minutes, no change.
The second machine has the 9400GT card so I tried the 8600GT card in it just to be sure the card was bad and got the same result on this machine. When I put the 9400GT card back in. I got the same issue. No signal display on the monitor. I also get no display when I connect to the VGA port on the Mobo.
I reseated the card several times and reset the bios.
On both systems all the lights come on and flicker as normal, when i connect speakers during boot I can hear the windows chime so the OS is loading. Currently I am booting both machines with the DVDROM disconnected which leaves only the hard drive.
Any ideas?
