I checked with the manufacturer for a bios update for my ram at Īnd there was a bios update, so I burnt it to a disk on my wifes computer because by this time my comp was completely unstable even though I had taken the ram back out. My mobo is a nforce 680i LT and I recently bought another 2gb of ram bringing my total to 4gb, well my mobo had some serious problems dealing with the new ram and sometimes it would not boot up. Well I finally got this fixed, but it happened by accident.

There is nothing wrong with the acer monitor, if i plug in my old hard drive which has winXP on it, it works fine. The problem is that the nvidia vista 64 video driver does not recognize the acer monitor. I have a second monitor, if I unplug the Acer monitor and plug in my Viewsonic monitor and reboot then vista loads properly the nvidia driver loads properly and I get all the possible resolutions for that monitor. But the resolution is locked at 1024x768. Here is the crazy part, at that point if i unplug the monitor from the video card, and then replug it and then click the mouse a couple times the monitor wakes up and I can log in just fine. At that point the OS is loaded and it is waiting for me to login. When the boot screen comes up, it comes up normally does the ram check and then loads vista, the vista loading bar also displays but then right before it shows the windows logo the screen goes black and it says 'No signal'. However if i install the nvidia driver the monitor stops working. Now the default vista video driver works fine, but of course has no 3d acceleration so its not an option. So I bought vista64, and bought a new hardrive, put in the new hardrive and installed This box used to run winXP but I upgraded because I wanted to try vista64
