AMD FX-4130 not using all cores...?

The other day I decided to bump up my AMD FX-4130's clock speed to 4.0 from its usual 3.8 to see if I could get some more performance out of it. I DID NOT MESS WITH ANY VOLTAGE OR ANY OTHER SETTING BESIDES CLOCK SPEED.
I ran CPUID CPU-Z benchmark with improved results afterward. I decided to test it in a game so I started up CS:GO and noticed that instead of my usual 150+ FPS I was now getting 30-40 FPS.
At first I thought this was no big deal so I just reverted the overclock and got back on.

Same FPS. I tested some other games such as Fallout: New Vegas and Alien: Isolation to see if it affected them as well. Fallout got to the main menu and then crashed on me. Alien Isolation started up and I could play a survival round but after I died and tried to restart the round the game crashed on me as well.

So I went into my BIOS and from there I reset it to the optimized defaults and the fail-safe defaults with neither of them being effective. I removed the CMOS battery and still had the issue.

From there I tried several fixes I found online and I eventually resorted to reinstalling Windows 10 through the reset option in the Settings. This still did not fix it so I removed my processor and put it back in and this did not fix it as well. I had noticed with CS:GO that whether or not I had multi-core rendering on or off didn't matter and I received the same amount of FPS. I decided to dig into that and everywhere I saw said that "Since its and AMD quad-core, Windows 10 will only show you 2 of the cores due to their architecture." Now I know this is true but before the issue, Task Manager had always shown that I had 4 cores and so did the resource manager. Now they will both only show 2 cores. CPUID CPU-Z was only showing 2 cores 2 threads and AMD OverDrive was also showing the same thing: 2 cores where it used to show 4.

I checked the BIOS and in the CPU settings I have all 4 cores enabled but I can't seem to figure out how or why this happened let alone how to fix it.

Literally any and all ideas would be appreciated right now as I have no idea what to do anymore.
Specs:
AMD FX-4130
AMD Radeon HD 7850
Kingston HyperX 4gb RAM
Gigabyte GA-78LMT-USB3
550W 80+ bronze PSU (I forget the brand)
(Please don't criticize my PC specs, I built this sometime ago with a small budget)
 
Solution
Loading up the default failsafe options in BIOS did nothing? If so, then you cooked a couple cores. They be dead. Likely damaged other parts of processor in the process.

AMD are actual cores I believe. It should be showing you all 4 cores. AMD doesn't have Hyperthreading like Intel does. A Dual Core intel will show 4 because of the Hyperthreading.
Did you document the changes you made? Reverting all of them (if you remember)

I'm not sure what happened really. This isn't the first time I've tweaked the settings and it has never done this in the past. BIOS are all up to date as of right now. I've narrowed it down to the fact that it isn't using all of its cores but I have no clue on how to fix this.

All I know is that it should show 4 cores like it did in the past and now its only showing 2. I went back and manually adjusted the settings (I wrote down all the changes I made in case it went awry) and then I separately tried loading the two default settings after that didn't work. Still no luck.

This is why I will never overclock my CPU. I will leave the overclocking to my GPU only for heavy intensive graphical games, but I always reset it after I'm done playing those particular games. I know my CPU bottlenecks my GPU though. But it's just something I have to deal with on my current PC.

{I hope you fixed your PC. Don't feel too bad about the specs. My PC has some of the same specs. I'm planning on building a new PC soon though. I will start with the AMD Ryzen 7 1700 and 16GB of ram among other things. It will take a while to build since I'm not rich either, but I'm going to buy one part per week starting soon.}

Current PC:
AMD FX 4130
AMD Radeon 7850 2gb
