I just upgraded my video cards to 2 x Titan Black Edition in SLI.
Everything seems fine, except I happened to leave the room while my computer idling, and when I returned some 20 minutes later I found my monitor black. I turned the monitor off and on again, and it reported no DVI signal. My computer was still running, and nothing seemed to be overheated - I touched the heat sinks on the CPU and video cards to check. So I pressed to reset button to reboot, and it was back to normal. It did tell me that Windows was improperly shut down, which of course it was because I reset it because I could not see the display.
Any idea why these video cards in SLI would suddenly stop outputting a DVI signal? I'd appreciate any feedback on this. I'm running an ASUS Rampage IV extreme, BIOS version 49.01.
Thanks for any thoughts on what could cause this.
