The situation of a computer freezing is familiar to almost every user. Most often these are small freezes that slow down the computer's performance and make working on it uncomfortable. But there are also more serious situations when the computer completely freezes and stops responding to user actions.
Instructions
Step 1
If the computer stably freezes some time after turning on or after you have launched some "heavy" program, first check the cooler (fan that cools the processor). Even if it rotates, a thick layer of dust can accumulate on the heatsink fins, preventing the processor from cooling properly. Clean the cooler with a jet of air or a brush.
Step 2
If your computer freezes accompanied by a blue screen and error codes, first check your RAM. Perhaps the cause of the malfunction lies in poor contact: carefully pull out the memory strips and wipe their contacts with an eraser, then put them in place. If after that the problem persists, check the RAM with the Windows Memory Diagnostic utility.
Step 3
In the event that the computer is old enough, carry out a general cleaning. Disconnect all cables from the system board, hard drives and drives, remove the video card. If you are not sure that you can reassemble the computer in the reverse order, sketch the position of all removable parts before disassembling.
Step 4
Thoroughly clean the system board, cooler, video card and other parts from dust. Use a jet of air or a brush for this. Wipe off all contacts and rebuild the computer. If the reason for the freeze was in poor contact in one of the connectors, the computer will start working normally.
Step 5
If the hardware of the computer is in order, the cause of the freeze should be looked for in the software. While the computer freezes, start the Task Manager and estimate the processor load. If it is 100%, look at which program consumes the main computer resources.
Step 6
To speed up the performance of your computer, disable unnecessary services: "Start" - "Control Panel" - "Administrative Tools" - "Services". Search the Internet for a list of services that you can disable.
Step 7
Check your virtual memory settings: Start - Control Panel - System - Performance - Options - Advanced - Virtual Memory. Perhaps for some reason the virtual memory on your computer is disabled or incorrectly configured. Select the System Selected Size option and save your changes.
Step 8
One of the reasons for the freeze may be the presence of malware on the computer. Check the functionality of the anti-virus program and the relevance of the anti-virus databases. If the antivirus does not find anything, install the AnVir Task Manager program. It allows you to conveniently view the list of processes, indicate the processor load, the degree of danger of running programs, startup keys, the name of executable files, etc. With this program, you can find and remove malicious software from the system.
Step 9
Check the degree of disk fragmentation by running the defragmentation utility: "Start" - "All Programs" - "Accessories" - "System Tools" - Disk Defragmenter ". Select the disk, click the "Analyze" button. If the program shows that the disk needs defragmentation, perform it by clicking the "Defragment" button.
Step 10
Remove all unnecessary programs from startup. To do this, run the msconfig utility: "Start" - "Run", enter msconfig and click OK. Select the "Startup" tab in the window that opens and uncheck the boxes for those programs that you do not want to start automatically.
Step 11
Clean the system registry with an appropriate utility such as RegCleaner or Registry Mechanic. A "dirty" registry significantly slows down computer startup.
Step 12
In some cases, the reason for the computer freezing lies in corrupted system files. The easiest way to fix the problem is to reinstall the operating system in update mode. Insert the CD with the Windows distribution into the drive, start the installation. At the very beginning of the download, select the update mode. In this case, all programs and system settings installed on the computer will be saved.
