pc locks up ,after reboot, sli disabled???

Ok i got a good one...hopefully i can get some ideas in this thread.

While playing WoW and I let it sit idle for like 15 20 min....My pc locks up...Screen just freezes

So i have to hard reboot and when it comes back up...SLi is disabled and dosent even show under the NVIDIA manager.

So Open the case...pull the bottom card out ( after its shut down ofcourse) and then reseat the card, Boot the PC and SLi is back on.

So i drop the OC back to stock on the cards and it keeps happening. Run 9+ hours of Orthos on the CPU overclock and 3 rounds of MEMtest and everything on that end is fine.

I cant figure it out to save my life. Any ideas??

Drivers are 177.83 Bios for 780i is P08

you have both of the 6pin PSU connectors connected to your video cards?
What video / mobo drivers are you using? Do you have the P08 BIOS?

bottom of first post...

still cant figure it out...

Tried new audio drivers cause it threw the BSOD code 0x00000124 which after searching around was audio drivers. But after the new ones, it still happens and i odnt have room for a pci audio card tue to the 8800gt's in SLI

downclocked the cards to stock...still does it.

ugh still doing it...im reading everywhere its the realtek HD audio drivers for onboard audio

but of course i cant fit my razor ac-1 card in with my GPU coolers.
