Thank you. I already opened a ticket. The PC is working at the moment, I'm afraid to open an unnecessary ticket.

Thanks for replying. When I select XMP, it shows me "Would you like to apply the all core enhancement with the XMP settings for improved performance? Sufficient processor cooling is required under all core enhancement". Confirm or Cancel. This XMP setting was used since 2015. XMP set 4.4 Ghz all cores. And yes, the PSU is working on my system. It's been almost 2 days trying to solve this problem. And so far I don`t know what happened. Self test failure without cables, self test failure with 8 pin CPU Cable and 10 pin(10+14) together, without short on motherboard. Is there any possible explanation of what happened, more specifically with bootloop and self test failure? Thank you

Firstly, English is not my native language. I apologize for any grammatical errors. I will try to explain my problem. Since 2015 I have never had problems with my PC. But 3 days ago I went to turn on the PC I got bootloop. It started and shut down infinitely. No buzzer sound or error code. I did self test and did not turn on the led. I turned off the PC, took out all the cables, and did the self test again. The led did not light up. I removed the memories, reseating memories, changed thermal paste, clear cmos, backup bios, removed GPU, reseating GPU and the same bootloop. I connected everything again for another test. If I remove the 8 pin CPU Cable the PC power on, self test work, but logically it does not show post. With the CPU cable connected and removing the 10 pin (10 + 14 pin) cable from the PSU, the self test work. I thought it was short on the motherboard. I tested the CPU connector with a multimeter and it did not have a short one. Measure CPU cable and shows 12v. Changed CPU Cable and same bootloop. I tested it with another PSU and the PC power on. I unplugged the power and reconnected after 24 hours and the PC power up again. No problem atm, but I remember when I reconfigured Bios, I activated the XMP and two options showed. One active all cores and another AUTO. I chose Sync all cores because I already used it. The PC shut off immediately. Reconfigured again and chose AUTO. XMP still on. Corsair Link does not detect the PSU and when it detects after hours, the information does not load. It gets frozen. This error has always occurred since the last updates of the CL4. Can the problem be the PSU or motherboard? Maybe CPU? The reports I see on the internet showed to be the PSU, but most with ASUS motherboards. Could you please help me? I hope my explanation did not get too confusing.
