The computer turns on and the power goes off immediately? Is the power supply insufficient?

Generally not, the boot speed is generally related to the system, the system is good and the boot is fast, if the power is small, the computer will not start, there will be no slow boot, I suggest that lz use the software to measure the power and performance of the whole computer, reinstall the system is not good for a higher power, I hope If it helps you, please remember to answer for satisfaction, thank you! Huaxia Alliance wishes you a happy life!

This situation generally has nothing to do with the power supply. Check your memory module, it may have been encountered when you changed your graphics card. Find an eraser to erase the gold finger of the memory module, and then restore or change the slot, and the problem may be solved.

Hey.. I didn't see clearly what you said about replacing the old graphics card. You can try the 300W, which generally requires 350 and 300W. My graphics card still requires 450w,Hehe。。

There are bigger ones. I can't find it and I can shop online. You're in luck with this power. If you're unlucky, it's not a power supply thing. It can break a lot of things. Such as hard disks, CPUs, graphics cards. will be due to the fact that your power supply is broken.

It should be this problem, or take the host to the computer city and let them help you solve it.

What graphics card can consume 350W? God card? Let's see if the power connector on your graphics card is plugged in.

What is the specific configuration of your computer?

What happens if the computer power supply is insufficient? 1. First of all, there will be a lack of voltage, which will damage the hard disk and lose the data in the computer. 2. It will also cause the computer's hard disk to make noise, and if the processor can't run, the heat will increase, so that the computer's motherboard is easy to be burned out.

3. It may also cause the computer to fail to turn on, at this time, the computer will not respond when pressing the boot button, even if it is turned on normally, it will not be able to shut down normally.

Suggested workaround:

1. If the power is insufficient to cause the failure of the motherboard or data cable, you can use the replacement method to eliminate the problem of CPU, power supply and other accessories, and then use the replacement method to lock the fault on the power supply, because the increased optical drive is the insufficient power of the computer power supply, resulting in the inability to read the disk, you can replace the power supply or uninstall the optical drive, and the fault will disappear.

2. For high-end graphics card computers, the power will generally be relatively large when starting, so it is necessary to replace a higher power power supply, generally GTX470 graphics cards above GTX470, with a high-frequency quad-core processor platform, need a power supply with a rated power of more than 600W, and HD5850 graphics card, with a high-frequency quad-core processor platform, also needs at least 550W power supply.

When the power is low, the computer will automatically restart. The computer power supply will power all the hardware. When the power supply is low, there may be things like memory loss or hard drive data loss, and random computers restart.

After the computer upgrades the graphics card, if you run the game at a high resolution, the blue screen will restart, and after changing back to the original graphics card, the blue screen will return to normal. It is basically certain that the problem is caused by a lack of power.

Insufficient power supply on the computer will cause the computer to restart.

First of all, rule out that the computer is not powerful enough, it may be a problem with the graphics card and memory.

The system is recommended to install the pure version (that is, the original version),The special version of the computer company is to save trouble and time when installing,It's a little inconvenient to use。

If your computer's power supply is running low, there are a few things that can happen:

1.System stability issues: Since computers often need to draw stable power from power sources to support the operation of various hardware and software, low-power power supplies may not provide enough energy and cause computer system instability.

2.Sound card or graphics card malfunction: Some devices with high power requirements, such as high-performance graphics cards, discrete sound cards, etc., require higher power supply power to function properly.

If your computer's built-in power supply doesn't provide enough power, these devices will malfunction, crash, and randomly restart.

3.Reduced performance: In order to avoid overloading the power supply, the computer may reduce the power consumption of some components to ensure stable operation.

As a consequence, the performance of the computer will be degraded. For example, the CPU frequency may be locked at a lower level, the graphics card will not work at full speed, and so on.

4.Unexpected Incidents: If the computer is operating at the upper end of the actual voltage fluctuation range, the voltage regulator and protection circuit components may not be able to react in time to prevent damage, and in the worst case it may lead to an emergency such as fire, ** or damage to the computer.

Therefore, in order to ensure the stable operation of the computer system and the integrity of the hardware plate, we recommend that users choose a model with sufficient power when purchasing a power supply, and make appropriate additional supplements according to the computer configuration and needs. If you are unable to determine the details around the power supply, consult a professional hardware engineer.

If your computer is running low on power, the following can happen

1.Computer system crashes and restarts: When your computer runs out of power, the system may crash or restart. This is because the computer can't get the steady power it needs, causing the operating system to not work properly.

2.Poor performance: If the amount of power** is insufficient, your computer's performance can be significantly reduced. For example, the application may be running slowly or stuttering.

3.Hardware failure: Insufficient power supply can also cause hardware failure. For example, if the CPU or graphics card doesn't have enough power**, these parts can overheat or even get damaged.

4.Data loss: This can lead to data loss if your computer is using insufficient power. For example, if important data is not saved during a system crash or reboot, it may be lost permanently.

Therefore, to avoid these kinds of problems, it is recommended that you choose a power supply that is powerful enough to use your computer, especially if you are using high-performance hardware on your computer.

1. If the power supply is seriously insufficient, the computer will not respond when it is turned on, and the host will not be lit. 2. If the power supply can be barely supplied, it is easy to have an electric banquet and shout brain instability, such as running some complex programs, such as running a game that is popped up or a crash screen. This is mainly because, in the common operation of games or some large-scale software, the power consumption of the computer increases, and the power supply cannot keep up, it is easy to crash, restart and other phenomena.

3. Buyou's computer does not recognize the storage device, and there is a strange sound on the hard disk.

Common phenomenon: 1. The computer cannot be turned on, the computer does not respond when the boot button is pressed, and there is no way to shut down normally even if it is turned on normally. 2. The computer often restarts automatically, and there will be an IDE SATA storage device when it is turned on, which cannot pass the boot self-test and stay on the motherboard information screen.

3. The computer has a screen of death.

Suggested workaround:

1. If the computer cannot be turned on or the boot button does not respond, you can use the charger that comes with the computer to charge, or buy the original charger of the computer to charge.

2. If the computer often restarts automatically, if it is inconvenient to replace the power supply, you can remove the hard disk and optical drive that are not always available, or replace it with a power supply with a larger power. To reduce the number of storage devices on board, hard disks and optical drives that are not commonly used, it is best to unplug the power and data cables.

3. For the problem of screen crash caused by insufficient function, the motherboard will be burned out, and a pressurization device can be installed for the computer to use.
