Strange hash rate/power problem

[afarzin]

I was mining away with my dual 5830s yesterday. Turned the computer off at night cause it was too loud. This morning I'm having this strange problem where the first card that gets started up works properly but the second card only mines at 1-2 Mhashes. Any ideas?

Is that actually the second card, or is the mining software seeing a CPU in the [1] spot instead of the second 5830?

Problem solved! I'd actually messed around in Bios and some power management BS was kicking in.
