The computer needs to be turned on multiple times

First of all, the phenomenon must be caused by low voltage or insufficient power, and the solution can be based on the following points:

1. There are poor contacts or inferior products in the power cord, plug-in board, and power interface, resulting in insufficient voltage or power supply.

2. The power quality is poor or the rated power is lower than or just near the critical point of the power required by your computer.

3. There are leakage components on the motherboard or there is a bug in the BIOS

In the first case, it is better to solve the problem, and it can be re-plugged or replaced.

In the latter two cases, you need to use the replacement method, and you can only find the installer.

According to your situation, the problem should be your power supply. You can open the case and take a look at the boot situation, whether the CPU fan turns or not, whether the GPU fan turns or not, if there is no problem, it should be a power supply problem.

First of all, no matter who installed it for you, it could be a problem with the power supply.

Another is that there is a problem that the CPU fan heatsink is in contact, and the CPU will turn off when it overheats.

Of course, it could also be a problem with the motherboard.

It needs to be taken a closer look. Acquaintances don't always pretend to be good, and make acquaintance money the fastest.

Tell you a way. Go to the hardware repair area to test if the contents of your case are normal, and if so, they are all normal. Then it's a system problem. From the installation system should be good!

I also had this problem on my previous computer, and it took me a long time to find out that it was a motherboard problem, and it was the same way, and it had to be turned on many times before it could enter the system, and it would automatically power off. Later, I took the motherboard to the warranty and replaced it with a new motherboard, and there was no such problem.

My motherboard with the problem was Onda N61S

Brothers. I had a similar situation with my computer the other day, and in addition to that, once it unplugged it, the time went to zero. I don't know if yours is the same as mine.

I made the system, the problem is still not solved, and finally I thought of the battery, so I replaced it, (pay attention to the method of changing the battery, try to wear gloves, not afraid that you will be electrified, for the good of your computer,) in the end, it will be fine.

But the next day when I had it turned on, it started very slowly, but I found that the time was right, and it didn't have any problems turning on at noon.

So I found out that my computer was caused by a dead battery and a fear of cold! Now everything is normal.

So you also change the battery and warm it up.

I feel like your computer is in bad contact.

The plug of the power supply to the motherboard is not plugged in tightly.

Either that's a problem with the front panel switch.

The problem should be with the motherboard or power supply. If the problem persists, you should be able to confirm that it is a motherboard problem.

Reinstall the system, if it can't be solved in this way, it's a hardware problem, the computer is going to be repaired, find your classmate's brother.

There is also a certain chance that the motherboard problem is a power supply problem.

It may be that the battery is dead, try changing the battery.

Problems with the motherboard or power supply It is recommended to replace the tests one by one.

1. If the computer is always automatically re-started repeatedly, the reason is likely to be that there is a problem with the switch of the machine, and there may be a power failure, the solution is to first check the boot switch of the host to see if there is a failure of the spring of the boot button, and friends with conditions can use the multimeter to test whether the power supply voltage is normal. Finally, if the CPU has poor heat dissipation, such as a bad CPU fan, it will also cause the computer to automatically reboot repeatedly.

2. The computer needs to be turned on several times, and the most common problem encountered by the author is the memory, and it is easy for this situation to occur when there is a small fault in the memory. The solution can be like this, we will take out the memory, wipe the memory gold finger, and then install it back to try, conditional friends suggest a new memory to try, there is no lack of macro new memory friends can consider removing it from a friend's computer to try, rule out whether there is a problem with the memory.
