CPU Troubleshooting

1.The noise of the chassis.

Fault phenomenon: to upgrade the CPU, the computer every time you turn noise particularly large. But after a while, the voice returned to normal.
Fault Analysis and Processing: First check whether the CPU fan fix bad chassis work and structure of some low-quality, easily in the boot of work caused by resonance, increased noise, in addition to the CPU fan and chassis fan motor add a little oil to try. If it is, it is best to replace the chassis because the chassis of the box single book.

2.The temperature rising too quickly.

Fault phenomenon: a computer running when the CPU temperature rose quickly, boot and only a few minutes the temperature rose from 88 ° F to 124 ° F and when 128 ° F to stabilize, no longer rising.
Fault Analysis and Processing: Under normal circumstances, the CPU surface temperature can not exceed 122 ° F.use could easily lead to system instability and hardware damage. According to the analysis of phenomena, warming up too fast, stable temperature is too high should the CPU fan, just replace the CPU fan can be a good quality.

3.The dust caused by the crash failure in the summer.

Fault phenomenon: computer failure, the phenomenon of using an average of 20 minutes will crash once, a few minutes after the reboot will again crash.
Fault Analysis and Processing: Start is estimated that the CPU temperature is too high in the chassis resulting in crashes in the BIOS, check the CPU temperature, the findings suggest that the temperature is only 91° F. Later discovered that the temperature was only 91° F check in the BIOS boot this computer to boot using one hours after the temperature increased by only 4° F, when the room temperature at 95° F. It seems the CPU temperature is measured is not accurate. Open the case found the fan on the heatsink too much dust accumulated above, has been transferred to fixed, then replaced the CPU fan, the next time you boot the computer running a few hours of the game did not crash phenomenon occurs. Later found that this motherboard temperature probes rely on the glue stick up in the heat sink to measure CPU temperature, while the probe and the heat sink close contact, separated from a great distance, the heat of the heat sink can not pass directly to the temperature probe measured the temperature of natural error. Replace the CPU fan, the probe and the heat sink paste together firmly fixed, so that the boot after 20 minutes, the temperature measured in the BIOS is 113° F, after everything is normal.

4.The CPU pins poor contact to cause a computer can not start:

Fault phenomenon: an Intel-CPU computer, usually been normal, Recently the problem.
Fault Analysis and Processing: First of all graphics card failure. Substitution method to check, but sometimes normal. Last unplug the plug on the motherboard, CPU, and careful observation there was no burnt traces, but found that the CPU pins are black hair green traces of oxidation and rust (CPU pin manufacture, the outer layer of gold-plated) copper material the CPU pins do the removal work, computer power.

5.The CPU caused the crash.

Fault phenomenon: in memory self-test through the boot of a computer after a crash.
Fault Analysis and Processing: Press [Del] key to enter the BIOS settings, double-check the settings no problem, and then read the default BIOS parameters, the crash still exists after the restart. Substitution method to detect the hard disk and various boards, the results of all the hardware. Estimation problem may be out on the motherboard and CPU, the CPU operating frequency to reduce one o'clock start the computer again, everything is normal.

6.The CPU fan led to the crash.
Fault phenomenon: when a computer's CPU fan turning suddenly fast and slow, use the computer for a while it will crash.
Failure analysis and processing: mostly due to the now common fan ball fan, need lubrication to lubricate the ball and bearing of this phenomenon is estimated between the ball of the CPU fan and bearing lubricants, resulting in increased fan rotational resistance, rotation difficult, so that the unsteadiness. The CPU fan can not be sustained strong winds to the CPU cooling, so that the CPU temperature to rise eventually led to the crash. Lubricant added to the CPU fan, CPU fan to turn the party crash phenomenon disappears.

7.The CPU frequency is not fixed.

Fault phenomenon: a computer every time you start when the CPU frequency is high and sometimes low.
Failure Analysis and Treatment: Most likely the battery on the motherboard without electricity caused. Replacement of the same type of battery, re-set the parameters in the BIOS, the CPU frequency display can be restored to normal.

8.The CPU caused by ultra-screen monitor black screen.

Fault phenomenon: a computer CPU overclocking boot display blank screen.
Fault Analysis and Processing: This failure is caused by typical overclocking failure. CPU frequency is set too high, the CPU does not work, and cause the display point light can not enter the BIOS settings. This situation needs to discharge the CMOS battery and reset to normal use. There are kinds of situations is the power-on self test properly, but can not enter into the operating system in time to enter the operating system crashes, this situation simply reset to start and enter the BIOS to change the CPU back to the original frequency can.
