Help! My New PC Build Keeps Rebooting Instead of Booting into Windows

I recently built my first PC, and it was working great for about two weeks. Then, it started freezing occasionally and eventually shut down completely. Now, it's stuck in a loop where it keeps rebooting. It gets to the BIOS screen but never actually boots into Windows 11. Here are my specs: Ryzen 7 5700, MSI B550M Pro VDH WiFi motherboard, 2x16GB DDR4 RAM at 3200MHz, ASUS Dual 5060 GPU, and a CX750M power supply. I've spent over 50 really frustrating hours trying various solutions. I've tested both RAM sticks in all slots, reseated everything that wasn't stuck, bought a brand new NVMe SSD, and updated to the latest BIOS. When I boot up, it shows the motherboard logo and attempts to load Windows, but before it completes, it turns off or sometimes shows a recovery screen. Then it automatically reboots, and the screen blinks a few times before shutting off again. I've even reinstalled Windows 11 about six times. Any suggestions would be greatly appreciated!

What slots did you use for your RAM? Since this is your first build, it's a good idea to isolate each component to rule out any failures. Make sure all the jumpers are set correctly and check that all fans, especially the CPU fan, are running. It sounds like something might be shorting out the motherboard but only after the POST process. Try unplugging all peripherals and testing again. If itโ€™s not the motherboard, check your storage and power supply next.

Have you tried clearing your CMOS? That could help. I recommend testing with different RAM sticks if possible, maybe borrowing from a friend or an older PC. Try installing Windows on a cheap HDD and booting from SATA or even running a Linux distro to see if that works. Is your computer POST'ing? Does it have any indicator lights on the motherboard or beep codes that might indicate issues? If you donโ€™t get any beeps or signs from your motherboard, you might need to replace it.
