. It is initially suspected that the CPU temperature is too high, but the CPU temperature tested by the software is still within the normal range. Fault Analysis: Many mainboards now have built-in control chips that can automatically monitor CPU temperature and shut down when the temperature is too high. However, if you set the BIOS warning temperature value to automatically shut down. Known solution: Go to BIOS settings and increase the "shutdown temperature" value in the "PC health" pr

In peacetime, we often remotely log on to Windows computers, although the Remote Desktop link tool provided by Microsoft provides the ability to remember the credentials, but we still have to prompt each time "system administrator does not allow the use of saved credentials to log on to the remote computer, because it does not fully verify its label, Please enter a new credential ", which will cause us to re-enter the password.Log off requires a remot

The author has encountered a case of such a failure two days ago, the process of troubleshooting is introduced to everyone, I hope to give you in the future to deal with such failures to do a

test, unsuccessful. It is good news, though not successful. Look closely at the application events log on SQL and find that SQL is always initializing after MSDTC restarts. MSDTC. did not prompt successfully. Then restart the server for SQL Server. Problem solving.Summary: There are a lot of articles on the web that address Ms MSDTC, but none of them speaks of restarting SQL Server.

But just after half a year, this LCD is a failure, the specific performance: As long as the start or restart the computer, there will be an approximate "flower screen" fault phenomenon, giving people the feeling as if there is high-frequency electromagnetic interference, the screen of the handwriting is very vague and jagg

Hardware issues Phenomenon: The system can start, there is video, failure prompts, at this time can be based on the tips to determine the fault site. The following are some common troubleshooting tips:First, the hint "CMOS Battery State Low"Reason: CMOS parameters are lost, sometimes can be started, using a period of time after the crash, this phenomenon is mainly due to the lack of CMOS power supply. For different CMOS power supply methods, take dif

The First: Cleaning method If there is conductive debris on the motherboard, as long as brush lightly with brush to the motherboard on the dust can be, the motherboard on some cards, chips are used in the form of pins, often because of the pin oxidation caused by poor contact, we just use the eraser to surface oxidation layer, and then plug the problem solved. 　　Second: The observation of the law In the event of failure, you can carefully observe the problem of the motherboard, to see whether

Sometimes the hard drive is in use, will suddenly "when" straight ring, and then can not continue to read and write, restart the computer again, in the BIOS can not find the hard drive. The more typical fault is just boot hard disk use normal, but when the use of one or two hours, the hard disk suddenly appear this abnormal sound phenomenon. From the surface analysis, this seems to be a hard drive of a chip instability caused hard disk work paralysis
