I installed a lot of software, but it won t start when it is booted up, will it slow down the system

No, you can clean up the registry.

Optimize it with Master Lu, and optimize it when 360 boots up. Anything else can only be replaced with hardware, and there is no special effect method.

1 Periodically, clean up the dust in the computer, open the chassis after shutting down, use a hair dryer, and blow cold!!

2 Usually use tools such as 360 Guardian and Kingsoft Guardian to clean up system garbage and temporary files (IE cache) generated by the Internet, and check and kill malware.

3 The computer configuration is poor, try to set the virtual memory to a larger one, (xp) right-click on my computer Properties Advanced Performance ......There the settings are advanced to change.

In the custom there is set to 2000 - 4000

Win7) Computer - Properties - Advanced System Settings - Performance Settings - "Advanced" Tab - Virtual Memory - Change - Select the drive C drive you want to set, select the system management size or select the custom size as you need - Settings - OK.

4 Antivirus software installation takes up a small amount of resources, such as NOD32, or only one auxiliary antivirus software is installed.

5 Try to set the IP to a static IP, which can reduce the startup time of the computer and the reflection time after entering the desktop.

6 Don't put too many files and icons on the computer desktop, which will slow down the computer's response, and try not to install the software on the C drive.

7 Close some startup programs. Start-Run-Enter msconfig-OK-Click "Start" in the "System Configuration Utility" window-Start, except for the input method (ctfmon) and anti-virus software, the general program can be turned off. You can also use 360 and other software to intelligently optimize boot acceleration.

8 It is recommended to install only one main antivirus, as installing multiple will take up computer resources and make the computer slower.

9 Regularly defragment the disk, open my computer To defragment the disk of the drive - Properties - Tools - select the defragmented disk to open the "Disk Defragmenter" window - Analyze - Defragment - the system will start to defragment.

10 Install a computer optimization software such as Optimizer or Super Rabbit, and the computer will be much faster under optimization!!

11 The current system also occupies a large amount of memory, and if necessary, adding more memory will be much faster.

12 The computer hard disk will be used for a long time, it will also make the computer slower, repartitioning and installing can fix the logical bad, the computer will be faster, and the physical read and write speed of the hard disk is slow, and it can only be replaced with a better !!

Hope it helps!!

I don't understand hi me!!

Well, try typing msconfig in the runtime and pick the one you need from the startup option. However, there are some necessary systems that should not be changed. If it doesn't work, go to the CMOS settings.

Viruses are messing around.

Install the anti-virus software McCafe.

Be careful to sail the ship of ten thousand years.

There are two possibilities, either poisoning, or too many cache files affecting the operation of the system.
