First, clean the disk and defragment it.

1. In my computer window, right-click the drive letter to be cleaned-Properties-Clean Disk-check the file to be deleted-OK-Yes. 2. Clear the temporary files, and then start-run-enter% temp%-OK.

3. Clean registry and junk files with optimizer or super rabbit. 4. Close some startup programs and start-run -msconfig- start. In addition to antivirus software and input method, general programs can be closed.

5. Delete the unused program software. 6. Defragmentation-Start-All Programs-Accessories-System Tools-Defragmenter-Select C- Analysis-Defragmenter.

Second, optimize your computer with an optimizer or a super rabbit, and then choose the following methods for re-optimization. 1. Disable idle IDE channels. Right-click My Computer-Properties, click Hardware, and then click Device Manager. Open the "IDE ATA/PATA controller" in it, then enter the primary and secondary IDE channels respectively, select "Advanced Settings", find the item where the "current transmission mode" is "not applicable", and put.

2. Optimize visual effects. Right-click My Computer-Properties-Advanced. In the performance column, click Settings-Adjust the visual effects to the best performance, or just keep some necessary items. 3. Click "Settings" in "My Computer"-"Properties"-"Advanced"-"Startup and Troubleshooting", and remove the options of "Write events into the system log", "Send management alarm" and "Automatic restart"; Set "Write Debugging Information" to "None"; Click "Edit", and in the notepad file that pops up: [Operating System] Timeout =30, change 30 seconds to 0 seconds.

4. Disable the error report "My Computer"-"Properties"-"Advanced"-Click "Error Report", click "Disable Error Report", and check "Notify me when a serious error occurs"-OK. 5. Set System Restore and click Start-All Programs-Accessories-System Tools-System Restore. In the system recovery interface, uncheck "Turn off system engineering recovery on all drives". In the Available Drives area, select the partition where the system disk is located, and click Settings to enter System Restore Settings.

6. Turn off automatic update To turn off automatic update, right-click My Computer-Properties-Automatic Update, and then select Turn off automatic update in the notification settings column. Check "I will update my computer manually".

7. Close the Remote Desktop. Right-click My Computer-Properties-Remote, and check "Allow users to connect to this computer remotely" on the remote desktop. 8. Disable hibernation. Click Start-Control Panel-Power Management-Hibernation to uncheck the box before enabling Hibernation.

9. Turn off the Inter time synchronization function, click Start-Control Panel-Date, Time, Language and Regional Options, and then click Inter time to uncheck the check box before "Automatically synchronize with Inter time service". 10. Turn off the disk index, turn on my computer, right-click the drive, select "Properties", and uncheck "Use index to find files quickly".

1 1. Disable redundant service components. Right-click My Computer-Administration-Services and Applications-Services, and set unnecessary services as disabled or manual in the right pane. 12. Close Dr.Watson, click Start-Run-enter the "drwtsn32" command, and open the window of Dr.Watson, leaving the option of "Dump all thread contexts" unchecked.

13. Set virtual memory. The minimum value of virtual memory is 0.5-2 times that of 65438+ physical memory, and the maximum value is 2-3 times that of physical memory. The method of setting the virtual memory is as follows: right-click my computer-Properties-Advanced-Performance Settings-Advanced-Virtual Memory Change-select the system letter in the drive list-customize the size-set the values in the initial size and the maximum size, then click the "Set" button, and finally click the "OK" button to exit.

2. What if the computer keeps crashing but the screen is stuck?

It is impossible to say that the memory of drive C is the smallest. I read your question. I think it should be the virtual memory, which may be super low. Please check whether your memory stick is damaged. Secondly, your file is damaged. Because the system file is damaged, you can't play games temporarily. Think back to what you have done. Third, the memory is full ~ but this possibility is that if the garbage is not cleaned regularly, the system will also crash, that is, there is too much garbage on disk C, and other disks combine fragments, plug-ins, startup items, service items and so on. Fourth, if there is a virus, it will naturally destroy the files in your system. You can't rule out this possibility, so you should also kill virus. Ok if you have any questions, please ask me.

3. The computer is often stuck, what is the reason why it can't move?

1, antivirus software is installed, and all monitoring is turned on. If monitoring is turned on less or not, viruses will often be killed.

2. The software or driver is incompatible with the system. Please reinstall or upgrade the driver.

3, system problems or Trojans, killing Trojans to restore the system or reinstall (download Win cleaning assistant to kill Trojans).

4. Unstable memory, graphics card and voltage will also lead to crash (if the memory is too small, add a memory stick).

5. Common hardware such as 5.CPU or graphics card is too high, which is most likely to cause card and crash.

6. If the hard disk has a bad track, use software to repair the bad track, format the hard disk partition and reinstall it, and change the hard disk.

7. Upgrading hardware will lead to incompatible crashes.

8. There are too many junk files and too many disk fragments.

9. If it doesn't work all the time, it is recommended to carry out an overhaul.

Use the system restore method that comes with the system:

System Restore: Start/Programs/Accessories/System Tools/System Restore, click Restore my computer to an earlier time, and then click Next. You will see that the date page has a dark date, which is the restore point. After it is selected, click Next to restore the system (Win7), and then select the device and security sub-options in the control panel.

Don't operate the computer at full load, that is, when playing games, watching videos and watching web pages, other operations are most likely to crash and blue screen, so don't operate other things when playing games, watching videos and watching web pages.

If your memory is small, it is recommended to add a memory stick to test whether the temperature of your CPU and other hardware is high, and if it is high, it will be cleared. The other is whether there is a problem with the hard disk.

4. Why is the computer always stuck on the screen, but the mouse can move?

Try to compare three reasons.

Advanced power management function is enabled in the BIOS of the computer motherboard, and it is also enabled in the windows system. The conflict between the two causes a crash or restart.

Insufficient space on disk C can also lead to hibernation crash. If the hibernation function is used, at least drive C of 1 G should be reserved.

Then there is the fault of the system itself, sometimes it can't be repaired unless the operating system is reinstalled (if the fault remains, replace the system installation disk). Usually turn it off when you don't use it for a long time, and have a screen protection when you don't use it for a short time.

Reinstall the system. Why not reinstall the system?

There may be many reasons for this situation, which is difficult to solve, but reinstalling the system can definitely solve it.

5. What should I do if my computer is frequently stuck?

In this case, if the computer has neither sound nor response, you can use the computer task manager to manage the program, and press "ctrl+alt+delete" to pop up the window of the task manager.

In the pop-up window of Task Manager, many running programs and their running status will be displayed. As shown in the figure, the running status will be displayed at the back of each running program, and some programs will be displayed as "no response" when the computer card is suddenly running.

As long as you complete the task with running software in a "unresponsive" state, or stop all running software and buy your computer, you will immediately respond and stop the card.

Sometimes the computer is so jammed that even the task manager can't be opened. At this time, you only need to cut off the power directly or let the computer run on its own for a long time, so it won't get stuck so slowly. This kind of problem often occurs, and it is necessary to carry out slimming treatment such as software deletion to improve the running speed of the computer.
