모니터에 아무것도 안 뜨는 컴퓨터 수리

정상적으로 동작하지 않는 컴퓨터가 입고됐습니다. 

 

 

 

기존의 메모리가 다시 꽂아봐도 인식이 제대로 안돼서, 제 메모리를 교체해서 출고했습니다. 

근데, 이상한 점은 원래 있던 메모리를 다른 컴퓨터에 연결하면 정상적으로 켜집니다.

손님 메모리와 메인보드 간의 문제가 있는 거 같네요.

The computer below is a Samsung computer that was released in early 2010. It's an old computer from 2010 to 2011. It's a computer that was received due to symptoms of screen failure. The main board is equipped with H55M01S1 Samsung OEM main board. When it was first stocked, I installed my memory DDR3 2GB as a test, so the screen turned on and went over to the desktop. My DDR32GB memory for testing had symptoms of mouse keyboard malfunction on my desktop. (It appears to be a memory issue.)

 

​

 

=> The memory connection is bad, so you can repair it and take it back if it works normally. If the above complicated situation occurs (if it cannot be solved at once), additional checks are needed, so I have to proceed with additional checks. = It takes time.

 

 

 

 

 

 

Repairing a computer that doesn't turn on

 

I wrote down your name in your memory and checked it by installing the guest memory on my test motherboard, and both of the guest memory were successfully passed on my motherboard.

 

 

 

 

I'm testing the memory by connecting it to my motherboard.

 

I put on a memory test and was looking at something else, so I passed the pass twice. I passed the remaining memory once.

 

 

 

 

 

 

Both memories were recognized normally and passed through the memory test program.

 

​

 

Below, I have installed my memory with the same capacity and speed of the customer's memory, and I am trying to boot it up and try the window operation. When I plugged in my memory, it started to boot, but the blue screen came up. My memory is already tested and stored in a memory box, so it is unlikely to be defective. There is a possibility that it is defective, but I think it is low.

 

 

 

 

 

 

I'm trying to run the window by plugging in the memory of the same capacity and speed.

 

We will remove the main board from the case and clean the memory socket. The socket is suspected to have a faulty connection. Since I don't usually remove the main board, I removed the CPU cooler to re-apply the thermal compound since I opened it up to here. There is a bulk Intel CPU with the LG mark on the Samsung body. (It doesn't look like the CPU you were originally using. Samsung will not use LG logo's bulk CPU, right? It's a computer that you've repaired in the middle, bought a second-hand computer, or seen your hand once in the middle.)

 

 

 

 

The CPU of the Samsung computer is equipped with an Intel bulk CPU with the LG mark on it. I think you got a replacement in the middle.

 

When replacing the CPU, we are removing the CPU and checking the status of the CPU pin to see if there is any damage to the CPU pin. There are some strange cases where memory connection is often bad due to CPU pin damage.

 

 

 

 

 

 

The CPU cooler fixing guide is almost integrated with the motherboard, so it doesn't seem easy to replace the cooler.

 

(Dum, this motherboard does not look easy to fit an Intel base cooler.) If you unzip the CPU retention guide and replace it with a guide for the Intel motherboard, you may also be able to install an Intel base cooler. I haven't tried it because the CPU cooler isn't broken, but I thought it wouldn't be easy to replace it while looking at the picture.)

It is recommended that the BW-100 be sprayed outdoors with good ventilation. The precautions on the back of the can say not to store in an enclosed space and never to inhale or drink. Check the direction of the wind carefully and I think I'll spray with my back against the wind. (When the wind blows, the fluid comes toward the body, so I think I'll spray it with the wind hitting my back. Especially when spraying, I think you'll be careful not to let the liquid get into your eyes.)

 

​

 

I scrubbed the substrate-wiping solo memory slot (as if I was scrubbing with a brush) with a BW-100 detergent. (Up and down) And the liquid left on the substrate will evaporate after some time, but it was blown out by the compressor and dried outdoors. When gunpowder evaporates, the ingredients do not disappear immediately, but they remain in the air, so outdoor work seems to be recommended.

 

 

 

 

 

 

BW-100 Rear Precautions, Outdoor Work Recommended, Avoid Eye contact

 

Before reseating the CPU cooler (BA31-00023B), re-apply the thermal compound and make sure that the CPU radiator does not get caught in the accessory next to it. In the days of the 775 cooler, depending on the direction of the CPU cooler, the cooler was caught on the accessory next to the CPU. Maybe it's because I designed it well after that, but it's not bad because I'm careful. If the CPU cooler is not assembled properly, the heat dissipation cannot be resolved, causing problems with computer use.

 

 

 

 

 

 

After re-applying the thermal compound, the CPU cooler is re-attached and secured.

 

When I plugged in my memory and operated it, it worked fine, so I replaced the memory and shipped it.

Below is a picture comparing your memory with mine. (The substrates are produced in Week 1242 below and Week 1211 above. The label on the actual memory card will be parked a little later. 1242 board => Week 1246) I couldn't see one of the components in the middle of the memory, so I thought it wouldn't work well because it fell off, so I compared it to other memory (1211) produced in the same year, but my memory is also in the same location. The probability that two memory parts of the same place fall together is very low, so it looks like this originally designed product. To make it a little more clear, I think it's better to find more memory of the same year and compare it by looking up the Internet.

 

 

 

 

Checking Memory Status-Checking

There was a board that had a memory recognition problem with the first generation Intel motherboard. Mainly the motherboard with four memory slots. There was a strange main board that didn't turn on when plugged in number 1, and the slots number 2 and 4 were recognized first. It's hard to see people using the first generation of Intel CPUs these days because the first generation of Intel CPUs went in early and moved on to the second and third generations. There are not many live computers in active use because the sales are low and many years have passed.
