The case of noise: Symptom: CPU computer after the upgrade, particularly when the noise each boot. However, after using a voice back to normal.
failure analysis and processing: First check the CPU fan is fixed, and some poor quality workmanship and structure of the chassis is not good, easy to work in the boot caused by resonance, increasing the noise, the other can give CPU fan, chassis fan motor Oil the test test. If the box is because the chassis caused by a single book, the best replacement chassis.
2, the temperature rose too fast:
failure phenomenon: When a computer running the CPU temperature rises quickly, turn the temperature up by only a few minutes or so up to 31 ℃ 51 ℃, 53 ℃ for however to stabilize , and is no longer rising.
failure analysis and processing: In general, CPU surface temperature can not exceed 50 ℃, it will lead to the phenomenon of electron transfer, thereby reducing CPU life. For the CPU temperature is too high for the next 53 ℃, and prolonged use could easily lead to system instability and hardware damage. According to the phenomenon of analysis, heating too fast, stable temperature is too high should be the CPU fan, you just replace a CPU fan can be of good quality.
3, summer dust-induced crash failures:
failure phenomenon: the computer fails, the phenomenon of using an average of once every 20 minutes it will crash, reboot again after a few minutes will crash.
failure analysis and processing: starting estimate is within the chassis temperature is too high CPU caused crashes in the BIOS to check CPU temperature, findings suggest that temperature is only 33 ℃. This computer was later found in the boot BIOS will only check the temperature of 31 ℃, start with 1 hour, the temperature rose only 2 ℃, at room temperature about 35 ℃. It seems the CPU temperature is not measured accurately. Open the case found that the fan on the heatsink too because the dust accumulation above the already turn no more, so replacement of the CPU fan, the next time you boot, the computer running for a few hours of gameplay are no backing out. Later discovered that the temperature probe is a piece of board by glue stick to the CPU heat sink temperature measurement up, but now the probe and the heat sink is not in close contact with, separate from a great distance, the heat sink can not directly transfer to the temperature probe, the temperature measured very natural error. Replace CPU fan, heat sink attached to the probe and the fixation with, so 20 minutes later in the boot, the BIOS in the measured temperature is 45 ℃, then use all normal.
4, CPU pin bad cause the computer to not start:
failure phenomenon: Intel CPU of a computer, usually used has been normal, Recently problems.
failure analysis and processing: the first estimate is the video card failure. After checking with the substitution, but sometimes normal. Finally, disconnect the plug on the motherboard's CPU, carefully observe the no burn marks, but found the CPU's pins are black, hair green, with traces of oxidation and rust (CPU's pins for the copper material, the outer layer of gold-plated), pins on the CPU do cleanup work, the computer power and can work.
5, CPU crash caused by:
failure phenomenon: a computer boot after crash in memory self-test passed.
Failure Analysis and Treatment: Press [Del] key to enter the BIOS setup, carefully check the settings no problem, then read the default BIOS parameters, restart crash still exists. Replace the hard disk and detected by a variety of boards, the results of all the hardware are normal. Estimation problem may be in the motherboard and CPU, the CPU operating frequency down a little bit start the computer again, everything is normal.
6, CPU fan led to the crash:
failure phenomenon: a computer's CPU fan rotation unsteadiness, while using the computer will crash.
failure analysis and processing: the ordinary fan is now mostly used ball fan, you need to lubricate the ball and bearing lubrication, this phenomenon is estimated CPU fan lubricant between the ball and there is no bearing, causing the fan rotation resistance increased, turn difficult to unsteadiness. CPU fan can not be sustained due to strong winds provided the CPU cooling, CPU temperature rise eventually lead to crashes. Added to the CPU fan in the oil crash after the party CPU fan rotation disappears.
7, CPU frequency display is not fixed:
failure phenomenon: every time you start a computer when the CPU frequency display high low.
failure analysis and processing: is likely to be the battery on the motherboard without electricity caused. As long as the replacement of the same type of battery, then re-set the parameters in the BIOS, CPU frequency display can be back to normal.
8, CPU caused by ultra-screen display a black screen:
failure phenomenon: a computer after overclocking the CPU, the boot display blank screen appears.
failure analysis and processing: This failure should be the typical failure caused by overclocking. The CPU frequency is set too high, resulting in CPU does not work, and cause the monitor point does not shine into the BIOS and can not be set. This situation requires the CMOS battery is discharged, and re-setting to work properly. POST also a situation that is normal, but can not enter into the operating system, when entering the operating system crash, in which case just start and enter the BIOS will reset CPU frequency can be changed back to the original.
failure analysis and processing: First check the CPU fan is fixed, and some poor quality workmanship and structure of the chassis is not good, easy to work in the boot caused by resonance, increasing the noise, the other can give CPU fan, chassis fan motor Oil the test test.
