What should I do if my computer shuts down for a longer period of time?

1. Choose Start> Control Panel> Power Options> enable advanced power management.
2. Check the computer device manager to see if there are any hardware devices with driver problems. If yes, reinstall the driver.
3. Disk fragmentation. My computer-right-click the drive to fragment the disk-> Properties-> Tools-> select a disk to open the disk fragment program window-> Analysis-> fragment-> the system begins to organize, the system will notify you after the process is completed.

4. Shut down all unnecessary programs before shutdown.
5. Choose master optimization> System Performance Optimization> disk cache optimization> remove the check box before "windows shutdown automatically clears page files.
6. Do not load DLL files. In [start]-> [run]-> type [Regedit]-HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer and create a dubyte value named AlwaysUnloadDLL with a value of 1. To remove this optimization, set the key value to 0.
7. Disable the "NVIDIA Driver Helper Service" Service, which is generally not required and occupies a lot of system resources. To close the feature, open Control Panel> Administrative Tools> services. In the displayed window, right-click the NVIDIA Driver Helper Service item and select Properties ", in the enabled drop-down list box, select disabled ".
8. Modify the registry to switch on/off the server: go to [start]-> [run]-> type [Regedit]-> [HKEY_CURRENT_USER]-> [ControlPanel]-> [Desktop], change the value of the string value [HungAppTimeout] to [200] and the value of the string value [WaitToKillAppTimeout] to 1000. in addition, in [HKEY_LOCAL_MACHINE]-> [System]-> [CurrentControlSet]-> [Control], change the value of the string value [HungAppTimeout] to [200]. change the value of the string value [WaitToKillServiceTimeout] to 1000.
9. If the above methods are ineffective, I think it is better to find a good system disk and reinstall Windows 7.
