1. Blue screen failure often occurs under Windows;
There are various manifestations of such failures, sometimes appearing when Windows starts, sometimes when running some software under Windows Appears, such failures are generally caused by improper operation of the user, causing damage to the Windows system. This phenomenon is manifested in the fact that when booting in 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 is not possible, only replace the memory stick. If the conditions permit, you can fix it according to the author's "Comprehensive Memory Fault Diagnosis of Computers" to see if it can solve the problem. ;
2, motherboard reasons. 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, because the CPU reasons for such failures are quite rare, usually common in the cyrix the CPU, which we can reduce the CPU frequency, see if you can solve, should not, only Change one way. ;
Second, the general protection fault occurs on your computer in normal mode on Windows startup;
reasons for such a failure occurs generally have the following:;
1, memory Reason. In the case of memory, we can change the CAS latency to see if it can solve the problem. If the memory is working at non-66MHz; FSB, such as 75MHz; 83MHz; 100MHz or above, we can reduce the FSB. Or try the memory frequency. If not, just replace it. ;
2, disk 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 the increase of bad sectors or the damage of the hard disk. Therefore, we should fix it as soon as possible. For the repair method, please refer to the article "Detailed Hard Disk Faults for Computer Comprehensive Diagnosis and Treatment". ;
3, windows system damage. This can only be solved by reinstalling the system. ;
4, opened the anti-virus features in 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 appear random crashes phenomenon;
crash failures are more common, but because it covers a wide range, maintenance is too much trouble, and now I will gradually be explain. ;
1, the virus causes frequent computer crashes;
the failure caused due to such reasons are quite common, when the computer is infected with the virus, mainly in the following areas:; < BR>
1 system startup time is extended;;
2 system starts automatically when starting some unnecessary programs;;
3 no reason to crash;
4 screen appears some garbled.
Its expressions are endless, due to space reasons introduced here, it is necessary to put together here, if the system is unstable due to virus damage to some system files, we can be in safe mode Repair the system files with the System File Checker. ;
2, due to the poor thermal stability of certain elements such failure (specifically in the CPU, power supply, memory, motherboard);
regard, we can let the computer running for some time, until After the crash, touch 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 reduce the temperature by about 5-10 degrees, especially On the computer of P; III; if the silicone grease is not applied, the computer will not work normally. I have encountered this kind of 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. ;
3, due to the various components of poor contact causes the computer to crash frequently;
such phenomenon is relatively common, especially in the purchase of a computer for some time. Since most of the parts are in contact with the main board by the golden finger, after a period of time, the golden finger part will be oxidized. After the cards are removed, the golden finger part will be yellowed. At this time, we can wipe it back and forth with an eraser. The yellowed area is cleaned. ;
4, due to incompatibility between the computer hardware cause frequent crashes;
phenomenon common in such cards are not compatible with other components or memory is not compatible with the motherboard, for example, the SIS card, Of course, other devices may also be incompatible. For this reason, other unnecessary devices such as modems and sound cards can be removed and judged. ;
5, a software conflict or damage caused by the crash;
such failure, usually occurs at the same point, this may be addressed to remove the software. ;
four computers appear when Windows starts * .Vxd or other system file is not found, press any key to continue fault;
such failures are generally due to the user not when you uninstall software If the driver is installed incorrectly or the hardware is incorrectly installed, we can enter the registry management program and use its search function to prompt the files that are not found to be deleted from the registry. ;
five in the Windows boot to the login dialog to normal mode, click "Cancel" or "OK" to the desktop with no icons, can not do anything. ;
such failures are generally due to the improper operation, resulting in damage to the system. The solution is as follows: First, we boot the system in safe mode, enter the control panel, enter the "Password" option, set the "User Profile" to "This desktop user uses the same desktop and preferences", then enter the "Network", will Delete the items other than "Dial-up Network Adapter" so that the login method is Windows login and restart the computer to solve it. ;
six or shut down the computer when the computer restarts in Windows;
I see the solution in a recent article reported that the computer is used defragment your hard disk or reinstall Windows to solve In fact, this kind of failure is generally caused by the user using the quick shutdown function of the Windows system when inadvertently or using some software for setting up the system, which causes the failure. The solution is as follows: Click “Start” - “Run” —“msconfig”, then select Advanced in the “System Configuration Utility” panel, select “Disable Quick Shutdown”, and restart the computer to solve it. ;
