Ask the master to help, and the machine will automatically restart

Such a problem, if it is determined that it has nothing to do with the system and software, but a hardware problem, generally appears in the power supply, motherboard, memory, hard disk, these places, since the power supply has been replaced, first take off the motherboard's coms battery buckle, (equivalent to discharging the BIOS). Redo the system again, if it still shuts down and reboots, then you try to change the memory.

In fact, shut down and restart, after redoing the system, don't install any hardware drivers, turn off the machine, and see how it goes.

In general, the hardware is a replacement, and the software is a step-by-step installation, and you should be able to see it if you try it.

But as a reminder, some have to do with the compatibility of the graphics card and the motherboard. If you can, you can change the graphics card, a different brand, try .

When you replace it, do you put it in the chassis for an interview or but test it?

1 Check whether there is a problem with the reset switch of the chassis Do not plug in the switch and the reset cable Use a metal object to connect the two needles of the switch of the motherboard to turn on the machine.

2 It's the replacement method to check the motherboard and graphics card.

Check your case power on/off.

You separate the motherboard from the chassis, that is, you don't use the chassis first, and see if you can reboot.

Power supply problems, caused by unstable voltage.

1. The minimum system method starts the system. Unplug peripherals, hard drives, memory, discrete graphics cards. Only keep the power supply, CPU, motherboard, boot the computer to see if the CPU fan is turning normally.

1. Normally, it is a problem to unplug the device, add memory and connect the display to the motherboard to see if it can be lit normally.

2. If the problem is still the same, it may be that there is a problem with the power supply or the motherboard, and the power supply problem should be eliminated according to the following methods.

2. Check whether the power supply is working.

1. Check whether the power supply fan is rotating, and if the power supply fan does not rotate, it is a power supply problem.

2. Do the three indicators of the keyboard (numlock, capslock, scrolllock) flash when the power switch of the host is turned on? If yes, the power supply is normal;

3. Are the power indicators and hard disk indicators on the host panel on? on, the power supply is normal. Because the power supply is not normal or the motherboard is not powered on, the display does not receive a data signal and obviously will not be displayed.

There are two power-off problems:

A: After 20-30 seconds, the power is off, and the fan on the CPU is loose: the motherboard and the chassis may be short-circuited.

Now the chassis is a piece of iron so it is not good to get the chassis frame is not good it is easy to short circuit you put the green and black short wiring of the power supply, see if it can work all the time put the power supply, if you can, then the motherboard problem, clear the battery under the motherboard to try.
