After a bunch of scary messages, weird red lines all over the screen, boot failures, and finally Win7 just refusing to turn itself on any longer, I finally figured out it was my primary 8800GTS which had died. After trying a bunch of things for a few hours, and looking up tons of threads on my laptop, I decided to swap the cards. Make the bottom card of my SLI rig the top, and vice versa. That worked, Win7 happily booted and Nvidia config reported exactly 1 card with no option for SLI. So I shut down again, and removed the (now second) card. Rebooted, and am running non-SLI with a single 8800 GTS. System is happy.
Here is the question. On the mobo (Asus P5N-E), there is this SLI removable credit card which you are supposed to turn around when installing SLI. By default, the SINGLE CARD part of the credit card is down. When I originally installed SLI about 3 years ago, I followed the directions to pull out that credit card, flip it around, and make sure the SLI part was down. In part of my troubleshooting to try to figure out this problem, I pulled both 8800 GTS cards, set the credit card to SINGLE CARD, put one 8800 back in, and rebooted. Nothing but scary beeps, no boot. So I put everything back the way it was including setting that little credit card to SLI again, but this time swapped the 8800 GTS cards and put the suspect 8800 as the number 2 card, and the secondary as the first card. When that worked, I shut down again, and pulled the bad 8800. That is the way I have it now. If you have been paying attention, you will realize that I now have 1 card in my system, but that funny little SLI/SINGLE CARD credit card still set to SLI.
I am very reluctant to switch it to SINGLE CARD because my system is now up and running (finally). Will it matter?
