I hope this is an appropriate post.

I have dual (are they always dual?) 8600GT SLI'd cards. They have been working great. Three days ago I woke up to a black screen. A windows Vista (32 bit) update had been installed. (I knew this because of a boot to safe mode). I tried many, many things but couldn't get it out of a black screen (the initial boot sequence would show on the screen, but when it came to swtiching to a higher resoluton and show the login screen, the signal would be dropped). So I flattened the machine.

It installed and then I went to Windows update and it installed the NVIDIA drivers. It rebooted and black screen again. Ugh. So I went to safe mode again and this time when I installed the NVIDIA drivers it worked. I could boot....but the maximum resolution it allows me to set is 1024x768. I have a Veiwsonic Vm2235 monitor so you can imagine this is pretty lame. SLI enabling work fine.

No matter what I try, I cannot seem to get theNVDIA control panel to show me resolutinos above 1024.x 768.

This is an EVGA card but I don't have the serial numbers because if I crack open the machine I void the warranty. If I bring the machine in for repairs, they told me it could be up to 2 weeks. Ugh.

If anyone has seen this before and knows how to fix it, please let me know. If this is a hardware failure (montior or card) please let me know as well.

My appreciation to all that help.
 
Sounds like the drivers are screwed up. I'm still waiting for Nvidia to write a decent Vista driver. You need to boot into safe mode uninstall all Video Drivers run driver cleaner and then install the newest version of the drivers.

Worse case you may need to reinstall the OS.

The rest of the specs of your machine would also be a help.

But I have money on the fact that this is a driver issue. Good luck.
 
Thank you so much. in fact, I didn't even have to boot to safe mode. I just installed and ran. It rebooted and everything is working. I can't believe how much time I invested in this problem and now I am free!!!!

Thank you again!
