Lenovo desktop computers boot up slowly! Ask a professional master for help

CPU temperature is too high Replace a high-powered fan Keep the room well ventilated The power supply voltage is unstable Buy a voltage regulator or UPS power supply Too many programs open Memory is heavily occupied Close unnecessary programs under msconfig End unnecessary programs Low CPU or memory configuration (Replace CPU to add memory) There are logical or physical bad sectors in the hard disk (find a professional to repair or replace) There is a virus Let's kill it Too many junk files Too many fragmented files ** Optimize the software, optimize it (Windows Optimizer or Super Bunny, etc.) System Problems Reinstall the system There are compatibility issues with hardware and software The BIOS settings are incorrect Resetting the BIOS Dust and moisture are to blame Clean up the chassis and keep the inside dry and clean.

Lenovo computers boot up very slowly, and the solutions are as follows.

1. Press the shortcut key to enter the BIOS setting when booting up, the shortcut key to enter the BIOS may be different for different computers, you can generally refer to the prompts at the bottom of the boot page;

2. After entering the BIOS, make sure that the hard disk is recognized under the information menu;

3. Go to devices-network setup;

4. Select PXE OPROM and press Enter.

5. Select disabled in the pop-up option and press enter to confirm;

6. Finally, press the F10 key to save the settings and exit;

7. In the BIOS, go to the Configuration or Advanced menu and set "PXE Boot to LAN" to disabled.

1. Turn off the NIC to start.

If the computer turns on the setting of the network card startup, it will aggravate the running process of the computer boot up, which will naturally delay the boot time, so temporarily turning off the wireless network card can improve the speed of the laptop boot.

2. Clean up the boot software.

Click the start menu on the main interface of the computer, click the run option in the menu bar, enter "msconfig" in the command box, then click OK, click start, and finally remove all the ticks, leaving only the input method and antivirus software.

3. Clean up system garbage.

Usually, most of the files will be hidden under the "Windows" folder of the C drive, which will take up space in the system and make the boot speed slower. Therefore, you can find the hidden folder with the "$" character under the Windows folder of the C drive, and see if it is an important file, if not, you can delete it directly. However, if you are not sure whether the contents of the folder are needed, it is recommended to clean up the memory junk through third-party software.

There are several reasons why the machine is slow:

1. The hardware configuration is too low; For the first problem, only part of the hardware can be replaced.

2. There are too many installed software and too many programs running in the background; Remove some software that is not commonly used and use a system cleanup tool to clean up the system.

3. The machine is infected with viruses and Trojans; install anti-virus software; System Cleaner Tool to Detect and Kill Viruses.

It is recommended to use a security guard.

4. Close the unwanted startup items, start-run-msconfig-start, in addition to anti-virus software, input method, general programs can be turned off.

5. Clear the temporary file, start-run-enter %temp% OK.

Three tricks to make your computer several times faster.

1. Reduce the waiting time of boot disk scan, start running, type: chkntfs t:0

2. Delete system backup files: After all kinds of software and hardware are installed, in fact, there are very few times when XP needs to update files. To start running, type in: purgecache and press enter, nearly 3xxmb.

3. Compress folders This is a pretty good optimization, Windows XP has a built-in pair. zip file, we can browse the zip file as a folder. However, the system uses some resources to implement this feature, so disabling this feature can improve system performance.

The implementation method is very simple, just cancel the registration, click start - run, type: regsvr32 u. Then press enter.

4. I have time to clean up the disk and defragment it, just get it once a month in the past two days, there are more harmful to the machine, and the method of defragmentation: my computer C disk right-click attribute tool defragmentation. Here's how to clean up your disk:

My computer C drive right-click on the property General Disk Cleanup.

First, disable some unnecessary boot items: shut down and restart, press "F8 key", select "Safe Mode" to enter the system, click "Start" Run" (or use the key combination "Windows key + R key") to bring up the run bar;

Enter "msconfig" in the run bar (or OK) to bring up "System Configuration";

In the pop-up system configuration dialog box, find the "Services" tab and click it, first check the "Hide all Microsoft services" item under the service label, then check all the non-Microsoft services listed in the above box, find out the services that need to be started at boot, and click "Apply" in front of the service item.

Click on the "Startup" tab, find out the unnecessary boot startup program, go to the previous "tick" and click "Apply" OK to "exit the "System Configuration", and restart the computer.

Start the computer normally and enter the system, and repeat the above steps again;

With the help of third-party tools, such as System Optimizer in PC Manager, the system boot is optimized again.

Slow for a reason. That's what needs to be optimized.

1. Run the "start" item, except for antivirus, you can prohibit startup if it is not necessary;

Second, "Computer" Advanced System Settings "Startup and Failure Recovery" settings "at the time of displaying the list of operating systems" and under "when needed......"Remove the tick from the front.

3. To defragment the computer disk, clean the registry, and clean the computer cache, it is recommended to use Windows Optimizer.

360 Security Guard, Optimization Acceleration, One-click Optimization, Scanning, Tick the options to be optimized, Optimize Now;

Or 360 Security Guard Optimize Acceleration Startup Items Select your target "Disable Startup" on the right.
