Hehe, brother, the computer I just bought has such a problem within a few days, so don't ask, just send it directly to the buyer for them to do!

You really have to do it yourself, I can tell you, that's why it's the hardest to judge whether it's good or bad. If you have to find out, send it to a repair shop such as professional hardware testing to test your computer hardware! !

You are not in the computer company, you are at home, and there is not so much hardware to try one by one. If possible, you can replace the hardware one by one by "elimination method" to eliminate the faulty hardware settings. Replace a power supply first, it doesn't work at all, so you can only replace it from the power supply first. If the power supply is changed or not, think about the key to turning on the power supply. (The reason is that you clicked it once, indicating that there are good and bad problems. Don't use the power to open the key. Use a small piece of metal (such as a screwdriver) to find two jumpers of the power supply on the motherboard and connect them with metal. Try this method. This method can only be done by people who understand hardware. If you don't understand, you'd better not try this step. If you make a mistake, you will burn the hardware. ) Not normal. If not, then I think you should consider the motherboard. Send it. !

Brother, the conditions you gave show that the computer company has no problem at all, nor does it say that the computer will recognize the Lord. In this case, I think you should consider checking the voltage in your community. I forget which article I first learned that two iron balls landed at the same time. Dare to deny it, just do as others say and measure your voltage with a voltmeter!

It's not the voltage anymore, so it's a last resort. Prepare two power sources (one is the power source of the computer that you have a problem with now, and the other is a good power source that you can guarantee to boot normally). Plug in the CPU and CPU fan on the motherboard, no memory, no graphics card (if it is an integrated graphics card, leave it alone). Connect the power supplies one by one and try to jump money on the motherboard with a screwdriver. If it is on, the motherboard will call the police, because the memory and graphics card are not plugged in, and the motherboard will call the police if it can't detect these hardware. Of course, don't worry about this alarm, which means that the motherboard, power supply and CPU are all fine, which is a good thing. If it's not so bright, I'll be finished!

I don't mean to be sarcastic, but my least favorite board is MSI! About six or seven years ago, P3 was still the mainstream of computers, and I was playing with it. The boards used at that time were basically 8 15E series. The board of MSI was ok when it first came, no problem, but after a long time, problems began to appear. It seems that all those boards have the same problem, and some old netizens should be very touched! !
