Have you tried plugging in another graphics card here? Yes, the 1080 I used before Yes, the same phenomenon is happening, and I have called the repairman again. He said it was a graphics card he was using for testing again, so I took it and put it on, and it came out the same again. The screen doesn't open, is this it? When I plugged it into the DP port of the main board, it came out, but when I checked it in the BIOS, NA appeared now. There is nothing wrong with the motherboard center. I went to the center, but the screen was output, I don't know what graphics card and power was used, but it was printed, and it was built-in graphics. Yes, that's why it's integrated graphics Why did Unifan plug all the power terminals into 4-pin PWM terminals? You don't have a controller for this? Oh, the controller? I ordered a controller, but you didn't buy it? I didn't know it existed Oh, so you didn't buy a package of 3, but bought all of them? The screen seems to go up, but it doesn't? really? Are you eating too much? But you said there was nothing wrong with the board? He said there was nothing wrong I also showed the screen once. Are you plugging in a graphics card? yes at there? graphics card? I don't know exactly, but it's a little small now Didn't you bring another power cable? Oh, the power cable? Yes, if you look here now, there is only 12VHPWR Oh, we need a power cable to plug in something else, but we have no choice but to test each one first. Because the board side says there is nothing wrong, but the actual user doesn't, so what to do? You just have to keep changing it over and over again. What settings did you do in the bios? There was no setting other than XMP. I'm the type of person who is afraid to touch it without permission, so let's plug the power into ours and take a look. First of all, I'll see if it pops up with the built-in graphics. Didn't it come up when you plugged in the graphics card even during the nude test? Yes, when I saw it, the board seems to be a strong one, but it seems to be a board. Why did it work there? CPU is Intel I7-13700K Yes, you can't even change the graphics card. I haven't been able to use it for two months because of this. two months? You haven't changed your CPU, have you? I didn't even go to the center. Yes, they haven't told me that there is a CPU problem yet, so I thought there would be no problem. Yes, if you want to doubt something, there is no end Did you update the bios to the latest version first? There won't be anything special at the center, and at first it went well, and then it went well? Did it go well at first? Was it used in the first place? Yes, it was used for a while, but the next day suddenly, I asked why it couldn't work after adding the HDD hard driver, and later I confirmed that the RAM was defective. I asked the center, checked for defects, and replaced them. Oh, changed the memory there? I replaced it, and then again, I did a full bank of the original RAM, which was not recognized. It has nothing to do with your full bank, right? I can't say again that it doesn't matter But now it's not full bank The board reacts, but it reacts. But the screen doesn't come up, isn't it a board problem? The VGA keeps giving me an orange light Did you change this to Gen3? link speed? Not sure about this? I didn't touch Still, it seems that you did a good job of assembling, but I also tried the graphics card vertically. No, it is not possible to directly plug in the graphics card, but is it said to be vertical? Rather, when I set up a vertical, it doesn't get worse or this problem occurs, but because the problems are so random If it didn't work with the nude test, don't assemble it. You assembled it. Finally, you need to change the CPU first. So now I just switch to the main board? I was even thinking about changing it. When I plug it in, the light comes out, but the light comes out, but I wonder why it can't be recognized. So, as if it could be recognized, he goes. Now oh, you applied a lot of thermal. Did you apply a lot? Yes, I applied it in the shape of an X, but I applied it a lot. I applied it a lot. Because you all inserted the guide and inserted the socket guide (private bracket). So, to remove it, in the past, you just need to open the latch and remove it, but you have all the guides attached. work is not easy Should I just remove the board to remove the CPU? If it doesn't work later, I'll have to remove the board. It's better to remove the board. If it doesn't work in the end, I have to remove the main board again, so I just remove the board. It's not easy. It's good that we attach brackets when assembling, but if there is a problem Especially those who are stuck behind You need to reduce half of the amount of thermal paste you have applied now. Is that enough? Otherwise, it overflows all over the side. So it didn't work when I did the nude test after I went to the motherboard center earlier, then I have to stop there. No bent sockets or anything like that. I'm going to plug in a 12th gen CPU There's a lot to do, so to test it after opening it, there's a lot more to bring. In the same way, connect it from the inside and see it, right? It's a 12th generation CPU. I'm going to reset the BIOS once again. It's initialized. It's up and I'm going to try the graphics card from now on. Are you saying it's plugged into the bottom of the graphics card? Yes I plugged it in and it works again Here, however, the method is 4x speed. Here, it is 16x speed. Uh... it works because I change the CPU? The CPU is the problem. Yes, I changed the CPU. Right now, of course, it's not a high-end CPU. We're using it for testing, so once we change the CPU, it wakes up right away. I don't think there's a need to try plugging in our graphics card here, so I'll plug in the customer's graphics card right away. I'll plug in the HDMI once and the DP once. It's coming up / It's coming up It looks like there's a high possibility that the CPU is the problem. It's a lot more than I thought. When we sent the defective CPU, we checked all the serial numbers, including the ones that were replaced with the existing serial numbers. It's a problem, so they never changed it at the distributor. So, after that, I check the serial number. Serial when sent, serial when received I think we need to see if there is a problem with the CPU. What about the rest... I'll try to install it again Just in case you don't know, I now have a sense of which part is the problem. Between board and CPU Board or CPU Board or CPU, try plugging the CPU in again. But this isn't fun again, but it's strange It's ridiculous, but it might work when this CPU is plugged into another motherboard and this graphics card is plugged in. I've seen cases like that I'm not going to put on a bracket for now, I'm just going to put it right away and test it. Because I'm like this, I should have used a Mac instead. Do you also use a Mac? Are you doing design or something? photo editing and video editing Did the graphics card fan just stop? It says that the board is responding normally, but it doesn't come out. As expected, the CPU doesn't come out again because it's stuck. Yes, that's right, it doesn't work because the CPU is plugged in. First of all, I even checked at the original location of the last CPU. B760M Mortar Max WIFI I'm going to test the customer's CPU 13700K now with the B760 board. The main board has been changed. Since M.2 is not connected, I will enter the BIOS directly. The important thing is whether or not the screen appears now. It's the same, CPU failure is 100% The board has reacted now. It is now responding to Easy Debug. I mean the board reacts. But the screen doesn't come up, it's the same symptom as before. This is a CPU failure. Maybe if you go to the center, you will check this way that Wherever you go, what's the problem with the CPU? I can't talk like this It's a defect. I have no choice but to replace it in this way, and the symptoms are the same. You can get this by going to the CPU. Even if you go to the center, it will come out the same I wonder if I was worried too I think that's for the customer to decide. Do you want us to act as an AS agent or go to the center and replace it yourself? If you know how to assemble everything because you have tested and confirmed everything like this, then you can go to the center and replace it and assemble it yourself, or you assembled it for the first time. It's embarrassing, but I can't do it, and it's a bit difficult to respond to the center, but then you have to leave it even if you just pay the cost. Intel I7 13700K CPU Service Center Arrived from Koit, a distributor It was exchanged and it was confirmed that it was defective. First of all, it's almost correct because I checked for defects and sent them out. The center also said they confirmed the defects. He sent me a replacement, but he gave me a phone call while sending it. I think he plugged the cpu upside down once He also said I can't put it upside down Did the customer ever say that they plugged it in wrongly? I'll install it and finish it. The i7-13700K is recognized well. Let's try booting Windows. There is a password. windows boots fine Normal booting goes well. Since the CPU is attached and detached, I think I can run Cinebench once to check the CPU temperature and finish it. I've been seeing a lot of CPU failures lately. Now, I played Cinebench once. In the case of Unifan, you haven't connected the controller right now. no controller at all It seems that the customer can finish this now, and I will finish it by replacing the 13700K AS. Ironically, the graphics card is not recognized due to a defective CPU. After replacing the cpu, the screen comes up normally. It's very unusual, it's amazing, and it would be nice if you could refer to the fact that these symptoms can also appear due to these causes.
