Computer Freezes When I try to Enable SLI

post #1 of 16
Thread Starter 
So I've had a single EVGA GTX460 for a few months now and with the great deals on them I went ahead and bought another one to finally have the SLI setup I've always wanted. I installed the second video card and bridged the two. Everything booted up fine (a little slower than normal but I figured because the computer is detecting the new hardware). I then uninstalled the video drivers and downloaded and installed the latest drivers. After a reboot I went into the Nvidia control panel, clicked on Maximize 3D Performance to enable SLI, and when I click apply it says its applying the changes, then the screen goes black and I hear the unplug/plug-in sound, my desktop reappears and then my computer freezes. Any ideas what the problem could be? I'm new to this and don't know what to try first.

Tried any other driver versions?

try going back to your previous drivers. Or reseating the bridge.

Ok so I looked and my old drivers were the latest drivers anyways, so I dont have any previous drivers to use that are an earlier version than the ones available online. I also tried reseating the bridge and I still freeze when trying to apply the changes. I will try looking for some old driver versions and try that, just out of curiosity though, why would using outdated drivers possibly fix this issue?

Ok so the new GPU is in by itself, been messing around in a few games, no problems so far.

Is one of your cards running at a different clock speed from the other?

Probably the bridge, if that doesn't work.
