Can t the host turn on normally at one time after power off?

It's the P35 chipset, right? If so, I can tell you that this is a common problem of the P35 chipset, and there is no cure (unless you brush the BIOS, but there is a risk, and it may not be solved), bear with it.

AMD's board, well, you can try to flash the BIOS, use the replacement method to check the graphics card, memory and power supply separately (to replace it with a wide power supply), if it still doesn't work, it's a motherboard problem.

If there is an error in the file system, run the disk troubleshooting program in XP. Method: Open"My computer", right-click the drive letter, and then select it"attributes"-"tools"-"Check for errors"-"Start checking", prompting two items of the disk check option"Automatically remediate file system errors"with"Scans and tries to recover bad sectors"Check them all and click on them"Get started".

It's a good idea to check all disks in this way. Check the system disk to be restarted (When asked whether to check when asked to restart, click.)"Yes"After restarting, it will be checked with a blue screen, wait patiently.

It is not recommended to use an inferior power supply, change a power supply and try again, Intel's machine, sometimes there will be this problem.

Do you have a problem with the voltage in your home? I suggest you replace the power supply and give it a try.

Or you unplug the hard disk and optical drive first, and try to turn on it normally.

It is best to use the power switch on the motherboard, this situation may also be caused by the poor contact of the power switch of the case.

1. The reason for the power failure protection of the main land machine after a while: the power supply is unstable, the voltage is not enough or it is broken. Poor motherboard power contact. The CPU conducts heat poorly, overheats, the CPU fan does not rotate or rotates slowly, or even breaks.

2. Solution: To check whether the capacitor on the motherboard has a protrusion, if there is a capacitance protrusion, it means that the motherboard has been burned out early. If the computer is powered off for a period of time after it is turned on, it is necessary to enter BOIS after restarting, check Lu Xishu to see the fan status, if the fan status is:

null。Indicates that the CPU fan is damaged. If the fan is damaged and the CPU temperature is too high, the CPU will automatically power off for protection.

So, if the fan is damaged, replace it in time. Check whether the power supply is damaged, check whether the power supply has a short circuit, etc. Damaged circuits and unstable voltages can cause computer power outages.

Touch the CPU fan to see if it is hot, if it is hot, it means that the CPU fan, the heat dissipation function is not good, you have to remove the fan and add silicone.

There can be a number of reasons why your computer console can't start due to intermittent power outages. Here are some suggestions and possible workarounds:

1.Power issues: It could be a problem with the power adapter or power cord. Try replacing the power cord or power adapter, or check the power supply unit (PSU) for signs of damage or overload.

2.Power Management Settings: Go to BIOS or UEFI settings and check the power management settings. Make sure to set to high performance mode to get enough power.

3.Memory issues: Memory failures can cause your computer to lose power intermittently. Try wiping the gold finger of the memory module, or replacing the memory module.

4.Motherboard issues: There may be a short circuit or other problem with the motherboard. In this case, the motherboard may need to be repaired or replaced.

5.CPU cooling issues: An overheated CPU can cause your computer to lose power intermittently. Check that the radiator is installed correctly and that the silicone grease is dry or aged. Make sure there is good contact between the heatsink and the CPU.

6.Graphics card issues: Overheating or malfunctioning of the graphics card can cause intermittent power outages. Check your graphics card's heatsink to make sure it's working properly. If necessary, replace the graphics card.

7.Hard drive issues: Hard drive failures can cause your computer to lose power intermittently. Try replacing the hard drive, or check the hard drive for bad sectors.

8.Virus or malware: Your computer can be attacked by viruses or malware that can cause system instability. Use anti-virus software to perform a full scan and check for viruses.

9.Wrong BIOS or UEFI settings: Check the BIOS or UEFI settings to make sure there are no wrong settings. If you are unsure about the settings, please restore the default settings.

10.Operating system issues: Corrupted or misconfigured operating system files can cause your computer to lose power intermittently. Try reinstalling the operating system, or use the System Restore feature to go back to the previous state.

Try the above methods and take appropriate actions according to the actual situation. If the problem persists, it is advisable to seek help from a professional technician.
