While using the computer to enjoy the fun of the Internet, we also have to face all kinds of weird problems that appear in the computer, today Xiaobian collected some common faults of the Windows operating system on the network. Solution summary (this article applies to Windows XP/Vista/Win7/Win8), I hope that everyone can learn knowledge with the soft media Xiaobian, and secondly hope that the following methods can play a role when everyone encounters the corresponding problem.
First, blue screen failure often occurs under Windows
There are various ways to perform such faults, sometimes appearing when Windows starts, sometimes when running some software under Windows, such faults are generally Due to improper operation of the user, the Windows system is damaged. This phenomenon is manifested in the fact that when the user boots in the safe mode, the system cannot enter the system normally, and a blue screen failure occurs. Sometimes too much fragmentation can cause such a fault. Once I solved the fault after finishing the fragmentation, if the rule is excluded, there are several reasons that may cause the fault.
1, memory reasons. This fault is common due to memory reasons. This type of fault is usually caused by poor chip quality, but sometimes we can solve this problem by modifying the delay time CAS in the CMOS settings (change it from 3 to 2). If it does not work, only replace the memory module.
2, the reason for the motherboard. Due to the reason of the motherboard, the probability of causing the fault is slightly lower than that of the memory. Generally, after such a fault occurs due to the motherboard, the computer generally does not crash after the blue screen, and the fault occurs frequently, and only the motherboard is replaced.
3, CPU reasons, due to CPU reasons such a phenomenon is relatively rare, generally common on the cyrix CPU, we can reduce the CPU frequency, see if it can be resolved, if not, then only replace one way.

Second, the computer appears
General Protection Fault when Windows starts in normal mode SUCH The reasons for the failure are generally as follows:
1, the reason for the memory. In the case of memory, we can change the CAS latency to see if it can solve the problem. If the memory is operating at a non-66MHz FSB, such as 75MHz, 83MHz, 100MHz or higher, we can reduce the FSB or memory frequency. Let's try it. If it doesn't work, just replace it.
2. The disk has bad sectors. If it is caused by bad sectors on the disk, we can boot the system in safe mode, and then use the disk scanner to fix the hard disk error to see if it can solve the problem. If the hard disk has bad sectors, if it is not repaired in time, it may lead to an increase in bad sectors or complete damage to the hard disk. Therefore, we should fix it as soon as possible.
3, Windows system is damaged. This can only be solved by reinstalling the system.
4, anti-virus function is enabled in the CMOS settings. Such failures usually occur during system installation. Turning this feature on after the system is installed generally does not cause problems.
Third, the computer often appears random crash phenomenon
Dead machine fault is more common, but because of its wide range, it is more troublesome to repair, now I will gradually explain it.
1, the virus causes frequent computer crashes
Because of such reasons, the phenomenon of this fault is more common, when the computer is infected with the virus, mainly in the following aspects:
1 system startup time is extended; Br> 2 system starts automatically when starting some unnecessary programs;
3 no reason to crash
4 screen appears some garbled.
The form of its expression is endless. Due to space reasons, it is necessary to mention that if the system is unstable due to virus damage to some system files, we can use system file check in safe mode. The system files are repaired.
2, due to the poor thermal stability of some components caused by such failures (specifically in the CPU, power supply, memory, motherboard)
In this regard, we can let the computer run for a while, after its crash, and then Touching the above parts by hand, if the temperature is too high, there may be a problem with the part, we can use the replacement method to diagnose. It is worth noting that it is best to apply some thermal grease when installing the CPU fan, but I can hardly see it on some assembled computers. It has been proved that the silicone grease can lower the temperature by 5— about 10 degrees, especially On the P III computer, if the silicone grease is not applied, the computer will not work properly. I have encountered this phenomenon once. The main configuration of the machine is as follows: 磐英815EP motherboard, PIII733CPU, 133 FSB 128M memory stick, when the machine is assembled, it crashes frequently, even the Windows system can not be installed normally, but after replacing the CPU of the Celeron 533, troubleshooting I suspect that there is a problem with the motherboard or the CPU, but the fault cannot be solved after replacing the motherboard and CPU of the same model. Later, due to the fact that the temperature was too high, some heat-dissipating silicone grease was applied to the CPU, and the fault was completely solved. Practice has proved that in the Celeron 533 or more CPU must be coated with thermal grease, otherwise it is likely to cause a crash.
