What about the computer motherboard overheating?

Computer motherboard overheating Solution:

The main reason for the motherboard overheating is the high calorific value of the video card and processor, and the heat in the chassis is not able to dissipate in time, the following measures can be taken to cool down:

1, inside the chassis and the motherboard dust more.

2, check the chassis ventilation channel is not smooth and the fan running slowly.

3, Motherboard North Bridge Radiator is not strong, the North bridge temperature will lead to high temperature board.

4. Run multiple programs and multiple games at the same time.

5, the motherboard thermal design error quality is poor (very few).

6, using the Pentium D8XX series of processors (will cause the motherboard temperature is high).

7. Whether the main box is placed in the place of the ventilation (air does not circulate causes high temperature in the chassis).

8, the motherboard sensor damage caused the motherboard temperature unchanged.

Motherboard temperature is too high solution:

1, regular cleaning of the chassis and the motherboard dust. (Dust is the bane of the motherboard)

2, to the chassis to install a better cooling fan. (Cool extreme Good, recommended to install 12cm fan)

3, a new bridge to replace the radiator. (I recommend Kyushu Ice Bridge 3 Generations)

4, run a single program or a single game. (Check the motherboard temperature is not high)

5, is really the motherboard quality is poor (had to change the motherboard)

6. Place the computer host in the ventilation department.

Problem analysis caused by motherboard overheating:

1. The motherboard anti-virus is not closed, causing the system to not install

Symptom: An old Celeron 333-configured computer, installed Windows 98 o'clock, found a black rectangular area suddenly appearing on the screen during the initial installation phase, as if there was a hint, and then stopped installing. Adjust the display brightness and contrast switch is also invalid, feeling and virus-related. Use anti-virus software to kill the virus, and did not find any virus. Later, the person pointed, entered the CMOS Setup program, the "BIOS Features Setup" (BIOS feature settings) in the "Virus Warning" (Virus warning) option from "Enabled" (allowed) set to "Disabled" (Prohibited), The reload of Windows 98 was successful.

Failure Analysis: This phenomenon is relatively easy to appear on the newly purchased motherboard because most of the anti-virus settings in their BIOS are set to Enabled by default, so there is a problem that the system cannot be installed. This problem is strictly speaking, the motherboard failure should not be counted. But often many users are not very careful, leading to frequent occurrences. Therefore, it is necessary to mention, for similar failures, as long as a careful look at the motherboard instructions can be done.

2. Motherboard temperature disorder caused the motherboard "suspended animation"

Symptom: The ASUS P3B-F Motherboard has an intelligent monitoring chip, so the CPU temperature can be monitored. When purchasing the motherboard, buy another 2Pin temperature monitor line, inserted in the JTP pin next to the CPU slot. Later in the process of playing the game, the machine suddenly blue screen, restart, wait until the CD-ROM drive, hard drive since the test after the monitor actually does not light. Since the blue screen error was previously reported, it was initially assumed to be an error in memory and is still invalid after replacing the memory. Again began to suspect CPU failure, changed a Pentium III 450 CPU, the fault remains. Barina, suddenly found that the original motherboard on the temperature control line off, dropped on the motherboard ... Is the temperature monitoring line caused by the fault? Reconnect the temperature monitoring line, and then boot incredibly everything is normal.

Failure Analysis: Due to the CPU heat is very large, so many motherboards have provided a strict temperature monitoring and protection devices. The general CPU temperature is too high, or the motherboard temperature monitoring system failure, the motherboard will automatically enter the protection state. No power up or alarm prompts. The above example is due to the motherboard temperature monitoring line off, resulting in the motherboard automatically into the protection state, refused to power. So when your motherboard does not start or alarm, first check the motherboard temperature monitoring device is normal.

3.IRQ Setup error causes mouse to not be available

Symptom: An older 586 computer that is not available when you install Windows or when you start Windows. Start to think is the mouse problem, the replacement is still occasionally a similar failure. Replace the mouse again, the problem is still, suspected is the motherboard PS/2 mouse interface failure, get professional motherboard detection point check ps/2 normal mouse mouth. It was later found that the CMOS parameter setup error was caused.

Failure Analysis: Because there is a modem use IRQ item in the power management bar of the CMOS Setup program, the options for this machine are 3, 4, 5 ..., NA, the general default option is 3, and set it to an interrupt other than 3. Such failures are generally common in older 586 PCs, and newer motherboards generally do not have this problem. On some old 586 computers, the COM port and LPT port are connected to the chassis by a signal cable. Its COM port signal connector with the motherboard is different, the method is also different, if the wrong connection will also lead to the mouse is not available, it generally has the following two kinds of methods: ① signal Line in accordance with the order of 1 to 9 connected to the head; The ② signal line is connected with the connection point, and the connector is connected with 1, 3, 5, 7, 9 of the signal line respectively, and the following row is 2, 4, 6, 8.

4. Motherboard overheating causes frequent crashes

Failure phenomenon: A TUALATIN/256MB ddr/geforce2 MX440 host frequent crashes, thought to infect the virus, after the killing did not discover any virus. It is also believed that the hard disk is too fragmented, causing the system to be unstable. But defragment the hard disk, and even format the C disk Redo system, but after a period of time and repeatedly panic. Start thinking about the hardware's own problems ... Later check out is the motherboard overheating caused instability, because the motherboard is a I845EP motherboard, poor workmanship does not say, and North Bridge without cooling fan, plus cooling fan, solve the problem.

Failure Analysis: generally for the motherboard or CPU problems, if this method can not solve the fault, it will only replace the motherboard or CPU. This type of failure is generally due to the motherboard cache problems or poor design of the motherboard, the author on a brand 815EP motherboard has been found due to the motherboard cooling is not good enough to cause the fault. After the crash, touch the CPU around the motherboard components, found that the temperature is very high and hot. After the replacement of high-power fan, the crash can be resolved. For cache problems, you can enter the CMOS Setup program, the cache will be prohibited after the smooth resolution of the problem, of course, the cache is prohibited after the speed that will certainly have an impact.
