What is the reason for the computer card screen? 1. Virus Trojans like to hijack thousands of system load points because of "why the computer screen is stuck". Kidnapping the normal files of the system caused the computer screen to get stuck. 2. There are too many startup items, and general programs can be closed except antivirus software and input method, so there are unnecessary services and planned tasks. There is too much rubbish in the computer system and a useless registry. System garbage includes the following contents: (1) window temporary directory, which stores all temporary files generated by the system and applications; (2) The window update patch directory is the place to store the patch installation package downloaded by the update program that comes with the system; (3) The browser cache directory is the place where web pages accessed by the browser are stored. 4. There are too many fragments on the computer hard disk. Solution 1. First, check whether your computer is infected with 1 virus, enter the main interface of Kingsoft Internet Security to kill Trojan 2, and then click Quick Scan 2. Clean up computer junk files 1. Open the main interface of Kingsoft Internet Security and click the "Garbage Cleaning" tab to clean up the garbage files, traces and registry. 2. Then click "Large File Management" to delete or transfer large files according to the scanning results. If you don't know which large files can be migrated, click here. 3. Click the "System Slimming" tab. Over time, there are more and more dispensable files in the system disk, which not only takes up disk space, but also affects system performance. Manual cleaning is neither convenient nor safe, and it can also intelligently detect and clean unnecessary files in the system disk.
