The motherboard connected to the CPU is the source of the fault. Generally, there are many problems that may occur. Why?

Generally, the problems that may occur are: 1. Jumper error. The CPU needs to change the motherboard jumper before it can be used. This includes FSB, multiplier and voltage. If the settings are wrong, a fault will occur. ; 2. BIOS error; 3. The motherboard is incompatible, and hardware conflicts may not be resolved by individuals. The best way is to avoid this when purchasing; 4. Incorrect fan installation will cause the CPU to be unable to dissipate heat, leading to computer failure. .

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

CPU is the most reliable product. First of all, it is just one component, the CPU itself. Secondly, its installation is the most convenient and reliable. Third, it requires no drivers and no software glitches.

But the problem often lies in the CPU. Why is this? Because the motherboard connected to the CPU is the source of the fault.

Generally possible problems are mostly as follows:

• Jumper error

• BIOS error
  

• The motherboard is not compatible
  

• The fan is not installed correctly
  

Scare, So many! No wonder my machine can't light up. If you are not sure about yourself, it is better to ask the merchant to install the CPU and test it before installing it, which will be much safer.

Jumper error:

This problem often occurs due to insufficient understanding of the motherboard. The CPU needs to change the motherboard jumpers before it can be used. This includes FSB, multiplier and voltage, such as Celeron 800. Its external frequency is 100MHz, the frequency multiplier is 8X, and the voltage is 1.7V. If the motherboard's FSB is set to 133MHz during installation, it may not light up. Because the CPU settings are wrong, when you use the 133MHz FSB, the CPU main frequency has reached 1066MHz, which is used during overclocking.

Motherboard incompatibility

When we upgrade the CPU, we will also encounter a difficult problem, which is the compatibility of the motherboard. Like early BX, 810 motherboards using the new PIII, or KT133 using high-speed Thunderbird, there will be compatibility issues. The current solution seems to be to update the BIOS and check online to see if the CPU you purchased is in your motherboard's support list. Some hardware conflicts are simply impossible to resolve personally, and the best approach is to avoid this at the time of purchase.

The fan is not installed correctly

If the system collapses inexplicably after a period of booting, check the CPU temperature first. This is often a complicated problem. Always appear in the simplest places. At present, there are many types of CPU packaging, which requires fans to cooperate with them. If you choose a fan that does not match well, it will naturally not achieve good results. If you use an INTEL series CPU, its original fan is very good. If you use another brand, there will be more problems.

CPU setting error solution:

If the CPU frequency settings are wrong, how to reset them. For motherboards that use hard jumpers or DIP switches, you only need to reset them according to the correct jumper method. However, the soft jumper motherboard can only be changed by entering the BIOS after booting the computer. However, the machine cannot be turned on anymore. How to enter the BIOS. The first method is to press and hold the INSERT key on the keyboard after turning on the computer. Many motherboards use this key as a switch to reset the CPU.

It will set the CPU to the lowest frequency and enter the BIOS. There are also some motherboards that define this function on the HOME button. This setting method often appears on AOPEN motherboards. If your motherboard does not respond to the above operations, you can use the method of clearing CMOS. There will be a clear CMOS jumper on the motherboard, and its location is next to the battery on the motherboard. You just need to close the jumper and the CMOS will be cleared. However, the above operations will clear the information in the BIOS. Settings such as hard disk, memory and password will be cleared and you will need to redefine them after booting.
