I solved the problem by trying the method in the link below (BR3). I am currently writing this article from the computer I saved. When I solved the problem, there was 1 RAM (8gb) in the slot. Solution: [URL] The only problem is that only 1 of the XMM slots are working (shown at the picture as 7), RAMs are Original 2x8GB DDR4 that comes with R6. I tried the RAMs separately in this working slot, the RAMs are fine, but when I try the other slots one by one (Slot 4,5,6) or when I try the working XMM slot and other slots as dual RAM (7-4, 7-5, 7-6) PC won't boot. I guess that was exactly the starting point of the problem, the BIOS doesn't show any settings related to XMM slots. If there is no solution for this, I will accept it as a mainboard issue and buy a new 2400mhz 16GB DDR4 and continue my journey with Aurora R6.   [IMAGE]Working Slot
Hi Everyone, A few days ago, I left the computer on and left the table, when I came back after a while, I saw that there was no image on the monitor and the mouse or keyboard had no effect, I turned off the computer by doing a hard reset, when it restarted, it started to restart without the alienware logo appearing, there was a cyclic restart situation. When I was doing research to overcome this situation, I came across a solution suggestion that CMOS reset can be done. I took out the CMOS battery, waited 1-2 minutes and put it back. When I restarted the computer, the leds on the Case were on, the CPU and Case fans were working, but the Monitor and RGB keyboard were not effected, so the computer would not boot. Another solution suggestion was that the RAM slots or RAM pins might be dusty and need to be cleaned. I took the RAMs out of their slots, cleaned them properly, and put them back in, following the instructions. When I restarted, I noticed that there was no effect on the monitor and keyboard, meanwhile the case leds and fans were still working. I tried again by removing the external video card from the board and plugging the monitor into the onboard video card and the result did not change. Thinking it might be a PSU failure, I installed another PSU and the result did not change. Finally, I took the motherboard out of the case, took out all the parts (including the CPU) one by one, cleaned the visible dust on it and reinstalled it, but the result did not change, but again all the fans and leds were working. My guess is that the CPU or Board may have been the problem, but if there was a problem with the CPU, it would be given as an error message with LED combinations as written in the User Manual. By the way, there is a led called HD# LED in the corner of the main board, I remember that it was lit as red normally, that led is not lit at the moment, I don't know if it reflects the current state of the PC? Also, does anyone know what this LED is for? I think I tried all the methods that came to my mind and came across in my research. I can take any suggestions. I am sharing the picture of the region I have specified as HD# LED. Power was ON when I took this picture.   Note: Warranty expired.   [IMAGE]Zoom       [IMAGE]General Look
