Fake CPU throttling

CPU: AMD FX-6300 (normal: 4.4 GHz, stock: 3.5 GHz)
Motherboard: MSI 970A-G46 AM3+

Today, I was trying to fix a RAM issue, so I resetted the BIOS by taking the motherboard battery out for 10 minutes, and putting it back in. This worked.
Unfortunately, after that, whenever I start up Task manager in Windows, it says the CPU frequency constantly remains at 1.36 GHz. No matter what kind of load I put on the CPU, it always remains at the same, unusually low frequency.

So I thought the temperature was too high, and the CPU was throttling, but no. The temperature remained at 26º C, which is almost room temperature.
After that, I tried changing the BIOS settings to force the original 4.4 GHz, but unfortunately, it doesn't work. I tried to disable AMD turbo boost, enable it, and set it to 'auto'. No matter what I do, including resetting the BIOS, the frequency always is 1.36 GHz in Windows.
Also, CPU-Z and Open hardware monitor say the same thing: 1400 MHz.

I have no idea what is going on, and this has never happened to me. My computer's performance is now 35% of what it originally was. Please help.
Can this be slowed by using Linux, or re-installing Windows?
In the meantime, I'll also try enabling OC genie II.

Try reloaded default settings on your bios (exit -> load default settings) and see ? But it will remove your overclock.

Might be stupid but also check your power options in windows, who knows maybe you are on saving mode or the CPU max frequency is limited to 30%..

The windows power setting is "Balanced". I never changed this, so I don't see why it would change today, without me doing anything.
And yes, I have tried using the BIOS's default settings, but theclock speed still is always below 1.4 GHz.
At this point, I'd be grateful if I could even get stock speeds, let alone getting my old overclock back.

Hey...wait!
I asked the same kind of question 7.5 months ago:

..and I found out that the solution was to disable AMD smart protection.
I guess that setting was reset when I resetted the BIOS, in order to fix the RAM today!
So I'll try disabling smart protection.
