Weird problem with Titan

I can no longer get output from a dvi and hdmi simultaneously. Each one will work on its own but when i plug a second one in nothing. Only the first one plugged on will get any output to my moniter and/or tv. It doesnt seem to matter which output i choose to use but only one will work at a time. Any ideas whats causing this. Its the same whether im Linux or Windows. It's obviously not software related. Could it be my PSU ( its a 750M Corsair ) or a physical problem with the Titan?

could you check on 2nd bios? (its dual bios right?)

its the first asus titan that came out, if it does have dual bios i sure wasn't aware of it.

hm, maybe some1 else has any ideas ~ or google ~
can't think of anything - but card itself.
