Problem: My i5-2500k cpu (asus p8p67 pro mobo) is stuck at its 3.7ghz turbo frequency.
No programs are running in the background, Ive tried ending every process in my taskbar, and it is still stuck at 3.7ghz,
The bios is at default except for changing the ram to 1600mhz.
Only thing I have done to my computer is connect a USB 3 external drive, and have recently replaced a defective graphic card I had, asus 6850, with an old gt 220, and then put in the new replacement 6850 today. It has never had this problem before.
