Hi all,
I've been chasing this issue for about two months now, and I figured it was time for me to stop lurking and reach out for help.
I have a PC with an AMD FX-6350 CPU, ASRock 970 Extreme4 mobo, and Sapphire Radeon R9 280 GPU, and 8GB of DDR3 RAM. Running Windows 10. (See build here: http://pcpartpicker.com/p/47fMjX)
I have been monitoring my CPU with CPU-Z to attempt to locate the problem. I notice that, most of the time, my Core Speed maintains a speed of 3.9 GHz. However, occasionally, it will drop to a troublesome 1.2 GHz. When this happens, I notice the following:
I notice no overheating during either of these scenarios.
A few things I have already attempted to resolve this issue:
I'm *almost* out of ideas at this point. My power supply is a Corsair 550W Gold. Running my build through http://powersupplycalculator.net/ tells me that my Load Power was around 440W. It recommended my power to be around 600W. I'm not entirely convinced that the problem is a power issue though, because I feel that I would be seeing different symptoms.
So, I'm hoping that someone else has had a similar issue, or knows which direction I should look.
Thank you!

I have been monitoring my CPU with CPU-Z to attempt to locate the problem. I notice that, most of the time, my Core Speed maintains a speed of 3.9 GHz. However, occasionally, it will drop to a troublesome 1.2 GHz. When this happens, I notice the following:
■ If I am browsing the Internet / File Explorer and open new tabs/folders, the tabs/folders fail to open and just hang. At this point, I can't do anything else, like alt+tab to another window, I just have to wait. After a few seconds, my CPU speed snaps back to 3.9 GHz, the tabs/folders open immediately, and everything is normal.
■If I am gaming, my FPS will drop from a steady 50-60 FPS to an unbearable 10-15 FPS. This seems to happen with every 3D game I play regardless of graphics settings (Rocket League, Total War Shogun 2, Fallout 4, Smite, CS GO....). After a few seconds, my Core Speed again snaps back to 3.9 GHz, and my steady FPS resumes.
I notice no overheating during either of these scenarios.
A few things I have already attempted to resolve this issue:
■ Installed an aftermarket heatsink. I purchased a (huge!!!) Cooler Master Hyper 612. It helped with what I originally thought was the problem (overheating). My PC now idles around 35 C and, under load, gets up to about 55 C. I've read that this is normal for my CPU.
■ Ensured proper application of thermal paste. I've applied thermal paste three times (after removal of the old paste, of course), in a thin layer across the CPU. It didn't seem to do anything for my temperatures, so I'm imagining this isn't the issue.
■ Installed a new motherboard. I had the Biostar TA970, and changed to the ASRock 970 Extreme4. No noticeable change.
■ Underclocking / overclocking my CPU. No change.
■ Underclocking / overclocking my GPU. No change.
■ Disabling AMD Cool 'n' Quiet. No change.
■ Ensured my Windows Power Settings were at High Performance.
■ Upgraded my computer from Windows 7 Ultimate to Windows 10. It got -generally- snappier when I did this, but the Core Speed problem still happened.
I'm *almost* out of ideas at this point. My power supply is a Corsair 550W Gold. Running my build through http://powersupplycalculator.net/ tells me that my Load Power was around 440W.
