I have an i5-3570k, and I was fine with it - until now. You know how these CPUs underclock themselves to save energy? Yes, well mine stays at that clock (around 1608 MHz according to CPU-Z) all the time. Even when I'm playing games or running Cinebench, it stays like that. Heat isn't the problem, it never goes above 40 degrees with my air cooler. I went into the BIOS and disabled the Intel SpeedStep thing - it still stays underclocked. I've refleashed the BIOS, erasing my overclock, still it continues. Does anyone please have any advice?

Try putting your BIOS settings to default and see if the problem persists.
Just tried that. I first noticed this when I fired up Borderlands 2. And started getting 30 FPS with a GTX 670 Really annoyed. I've done everything I can think of doing.
