Reason and solution of sudden shutdown of Dell Win7 system notebook computer

Reason and solution of sudden shutdown of Dell Win7 system notebook computer

Workaround One:

1, the first to use a comprehensive anti-virus software to check, to see if the virus, if found out, direct anti-virus to fix.

2. Check to see if the system file is corrupted, click Start Menu-Attachment-command prompt-run as administrator, and then use the Chkdsk command to try to verify and fix.

3, if the relevant machine software, first all directly to uninstall the test.

4, if the problem is driven, we can upgrade the driver to solve. We recommend that you download a driver wizard to detect the driver problem.

5, other problems caused by computer automatic shutdown.

Failure Reason:

General automatic shutdown may be the CPU fan dust too much caused by the high temperature caused, if it is, clean up the CPU fan and heat sink dust, new plus thermal silicone grease.

If this is not the problem, it may be the motherboard parts or power supply problems, voltage instability, hard disk failure and other problems caused by the new hardware is not compatible, if they do not find the reason to recommend repair, because the automatic shutdown is not a small problem. In addition, the system has a Trojan can also lead to shutdown, but the probability is very small, restore the system or reload try.

It may be a setup issue if you shut down or standby automatically without operating. Right-click the Desktop Select Properties/Screen saver/power supply/Select an option for you in the Drop-down list in the Power usage scheme, the following will turn off the monitor, turn off the hard drive, system standby, and set the list of these three contents to "Never" as applied (or set the appropriate time).

Turn on the Control Panel/turn on hardware and sound/Power Options/Select Turn off the monitor (select Never or set time)/Select the drop down list to make the computer go to sleep choose never or choose the appropriate time (Win7 system).

Workaround Two:

1, there may be a problem with the BIOS setup, enter the BIOS to restore the default settings or the motherboard of the battery to take out, reverse-buckle discharge, and so on 5 minutes in reverse loading can be. Objective: To restore the default values for BIOS settings, and to troubleshoot the automatic restart or shutdown of the BIOS's thermal presets.

2, if the computer in the use of an application software occurs automatically shutdown, the automatic shutdown failure may be caused by this program software, the general program software uninstall can be.

3, then check the power supply, power quality is poor, aging or power too small, can not meet the power requirements of computer accessories, can be replaced by high-power high-quality power supply, if troubleshooting, it is the power caused by the automatic shutdown failure.

4, then use the elimination method, check memory, video card, CPU, CPU fan, motherboard and so on.

5, check the memory, the quality of memory does not pass, heat dissipation, overclocking, different brands of memory mix and the CAS value set too low can cause computer automatic shutdown, available test memory, and the BIOS in the memory parameters are adjusted accordingly.

6, check the motherboard, motherboard aging, capacitor failure or slurry, motherboard power pins, motherboard and chassis backplane can cause automatic shutdown, the motherboard can be removed from the chassis check or test, and then check the CPU fan rotation and CPU temperature is normal, and then check the CPU fan heatsink bottom silicone is dry, If it dries, clean the silicone on the CPU fan and then paint the silicone again. If the fan is not normal, replace the CPU fan.

7, cleaning method: It is through the computer mainframe parts of the dust cleaning to eliminate the failure of the method. Dust is also can cause computer automatic shutdown failure of one of the factors, dust can cause parts aging, pin oxidation, poor contact and short-circuit and so on. For these faults caused by dust, it is more effective to use the cleaning method generally.

8, the power supply system is not stable, can also cause automatic shutdown failure, you can consider the configuration of a voltage regulator with the power supply of UPS.
