Stumped. How abt running both gpu & cpu stress tests together to rule out psu.

Disable say onboard wifi & sound to test? Check DPC latency to see if any spikes coincide with GPU usage drops? - actually I'm not even sure if DPC is related here, just grasping at straws.

And disconnect any non-essential hardware peripheral, if any. http://forums.steampowered.com/forums/showthread.php?t=2767721

Outta ideas here already, sorry frown.gif

Sorry haven't visited this thread in a while. Running Both CPU and GPU stres tests causes the gpu usage to drop. My conclusion is the PSU is bad. I got the http://www.newegg.com/Product/Product.aspx?Item=N82E16817703038 for a steal of $104 (Promos and Customer service Gift Card). I'll report back with results. Thank you all for your help!

Have you tryed in the nvidia settings to change to "prefer maximum performance"?

You could also try upgrading your motherboard drivers if you aint got the newest

Mayhaps you should give the card a small voltage bump.
