Thanks for the update.
Make sure you have the latest BIOS Version installed for your Processor. Unless the latest BIOS version is the reason for your troubles. The latest involves making the Mobo Windows 11 compatible.
Try doing a CMOS CLEAR on the Motherboard to reset BIOS back to factory "Defaults". Don't overclock the RAM at this time and leave everything as default. Unless it goes to CSM Mode by default. Then you need to change it to UEFI Mode. Also disable "Fast Start" in BIOS. Those should be the only changes made at the moment.
Just see if everything boots up and works. If it does then enable or disable all the other BIOS settings except your RAM Settings. Leave that in Default.
If everything boots up and works correctly now overclock your RAM and see if you start getting the 3 Beeps sequence again.
The above is to just eliminate any BIOS settings that might be having issues in UEFI Mode. I mentioned the RAM last because that is where the problem is indicating by the 3 beeps.
I downloaded your Mobo Manual and it shows it uses EZ DEBUG LEDs. So you can use that to troubleshoot your Mobo while it is booting up.
Make sure that BIOS is still in UEFI Mode.
If all above you are still getting the 3 beeps with BIOS in Default and EZ DEBUG DRAM LED is now lit up, then disconnect everything from your Motherboard except your PSU, CPU, and Windows drive.
The CPU LED light should go on and then off and the DRAM LED light should be illuminated. This means that BIOS tested your CPU and it passed the hardware test.
Install one stick of RAM in A2 or second DIMM Slot on the Motherboard. Now both the CPU and DRAM LED lights should go on and then off in sequence and the GPU LED should go on. It is a good chance the PC is still booting into Windows at this time.
Now connect the GPU card, Monitor, and Keyboard/Mouse still with one Stick of RAM installed without being overclocked.
If everything boots up fine without any EZ DEBUG LED lights constantly lit and no BEEP sounds now install another stick of RAM until you have all your Sticks of RAM installed without any beeps.
Now overclock them in BIOS and see if the BEEPs restarts again.
NOTE: I realize this is a lot of work but something is not compatible in Windows 11 UEFI Mode. The above is just a step by step way of trying to eliminate the hardware one at a time.
Also I don't believe you can enable UEFI Mode if your HDD/SSD has a MBR Partition. The Windows drive Partition must be GPT type.
You can check that under Windows Information screen in Windows Settings.
