Unable to Downclock CPU

After replacing my case fans, I got on to my PC and started browsing as well as playing a game. And then it happened. I was greeted by a blue screen with the words, WHEA_UNCORRECTABLE_ERROR. I let Windows restart itself and everything seemed normal. I opened up HWMonitor and it was showing me this:

I checked the "Power Options" in the settings and "Balanced" was all ready selected. I restarted my PC and booted up into BIOS. I selected "Optimized Defaults," saved and, booted back into Windows. HOWEVER, the CPU was still overclocked. I went back into the BIOS and found out that my changes weren't saved. I snapped a photo after selecting "Optimized Defaults" again:

My DRAM is also being a problem for me.

*I'm using Windows 10
 

So I'd do the following:
1. Enter Bios (restart machine spam f2 f11 and del(not sure which one your mobo is)
2. Look for something that says 'Restore to factory defaults' (probably under a tab labeled "exit")
3. Click that
4. Your golden.
 


I've all ready tried that. "Optimized Defaults" is pretty much THE default setting. Everytime I open up HWMonitor, it's still telling me that the CPU is overclocked. Going back into the BIOS and selecting that option shows me that the changes were NOT saved. They reverted.
 
If the "Restore to optimized defaults" setting on your motherboard is not working properly, and BIOS settings are not being reset, you may have to perform a hardware reset of your CMOS/BIOS.

To do this:

1.Shut your computer down.
2.Turn your Power supply switch to the "off" position, and unplug it. (Note- failing to do so will result in serious damage to your motherboard)
3.Take your CMOS battery out of your motherboard. (Again, failing to do so will result in serious damage to your motherboard)
4.Press and hold the "Power" or "On" switch to your computer for 20-30 seconds to discharge any remaining power in the capacitors.
5.Locate two pins on the motherboard that usually say "CMOS_RST", they are USUALLY on the bottom right of your motherboard above the input panel (Where your power and reset switch etc. are plugged in).
6. Create a short circuit between the two pins with a screw driver (Or anything conductive) by touching both pins simultaneously with the screw driver and holding it there for about 10 seconds.
7. Put your CMOS battery back into your computer.

Remember that when you do this, it will reset all BIOS options back to their original state. I take no responsibility for you damaging your computer if you do this improperly.


Now for your original problem.

"WHEA UNCORRECTABLE ERROR" is a generic description of an error called a "Stop_124" (0x124 hex), which can be caused by a lot of things but usually means the computer shut itself down to prevent damage because of a "Fatal hardware error."

Since this issue did not arise until you replaced case fans there are a few obvious issues that you should look for first. I will list them in order of severity.

1. Make sure you didn't accidentally create an electrical "loop" by daisy chaining the molex adapters on the fans together.
2. Make sure fans connected to your motherboard headers are connected properly.
3. Use speedfan or AIDA64 to ensure that your motherboard's PWM control hasn't been damaged somehow, use these programs to cycle their spin rate
very high and very low to make sure that they are responding to software/firmware commands. If they do not respond, try plugging a known good fan into the same motherboard header and repeat the process. If the second fan responds, you know the PWM control on the first fan is damaged, and the fan should be discarded, if it does not respond, there may be a problem with your motherboard.
4. Check for bad RAM modules.
 


Sorry for the late reply. Anyway, I don't want anything bad happen to my PC. However, I've read another thread from another person with a similar problem. It said something about updating the BIOS to fix this. Will that work too?

Also, my new fans are connected to my case's fan controller. I had to use this due to them being 4 pin fans:

My previous fans were connected to the motherboard before being replaced. I would also like to mention that both the error AND the inability to change the settings in the BIOS back to default, happened almost at the same time on the same day. 🙁
