Why my computer freezes up? – Top 12 reasons that may cause computer to freeze randomly

Reason 1: virus infections

Sometimes computer viruses can decrease your computer’s performance greatly. The symptoms may be very high CPU usage, slow computer speed, memory shortage, computer freezing problem, etc.

Reason 2: dynamic link library files (DLL) missing

In windows operating system, there is a very important type of file whose extension is DLL. The nature of such kind of files are belong to shared files, which means that a DLL file can be used by multiple applications during their running procedures. When we uninstall an application, the application’s uninstall tool may record all files that the application has installed on your computer and delete those files one by one. If the deleted DLL files happen to be used by other applications at the same time and the DLL files are important core linked files, then your computer may freeze up or even crash completely.

Here is a picture for how dynamic link library participates in the linking procedure so that you can understand better why an important missing DLL file will cause computer to freeze:

Reason 3: too little free disk space or too much debris

Some applications need large amount of memory to run smoothly, which will require sufficient virtual memory. Virtual memory is provided by the hard disk so the hard disk space has to meet the needs of virtual memory. If not, you may suffer from computer freezing problem. Therefore, computer users should erase junk files per week and develop a good habit of a regular defragment for the hard disk.

Reason 4: improper software update

Most people think software update won’t cause any problem. In fact, the update procedure will refer to some shared components and if other programs do not support the upgraded components, then various computer problems including freezing computer may appear.

Reason 5: beta software

Beta software always have some bugs and their performance are unstable, which may cause data loss, computer freezing problem,  system crash or even computer not starting issue.

Reason 6: illegal software uninstallation

Some users are fond of directly deleting applications from the installation directory. But this removal method will leave a lot of garbage on computer Registry and Windows Directory.  The computer system will become very unstable over time and then cause the computer desktop to freeze up randomly.

Reason 7:  pirated software implement

Some pirated software may be bounded with computer malware. Once you execute the pirated software with virus infections, then the viruses will modify your system immediately and cause your computer to freeze randomly.

Reason 8: application defects

Such kinds of problems is very common. For example, some applications perform very well on 32-bit windows system but they won’t work in 64-bit system at all.

Reason 9: too many programs at computer startup

If there are too many programs running at system startup, then they will eat out the system resource and then cause your computer to freeze up randomly. Sometimes, if a program cannot find out specific data from computer memory or virtual memory during the running procedure, system errors may also occur.

Reason 10: illegal operation

If you use illegal format or parameters to open or release relative programs, it will cause computer to freeze randomly. Thus, please remember the correct format and associated parameters for corresponding programs. Do not open or release unfamiliar programs arbitrarily.

Reason 11: abnormal computer shutdown

Do not shut down the computer directly using the power button, otherwise, it may cause the system file to be corrupted or missing and then cause computer freezing problems or even computer crash.

Reason 12: memory conflict

Sometimes you think all programs are running smoothly on your computer but suddenly your computer freezes for no reasons. After you reboot the computer and run those programs again, everything seems to go back to normal. Actually, this is a kind of fake computer freezing problem because of memory conflict. If an application which was not designed well cannot fully release all memory to return to your computer after it closes, then when the next application needs to use relative memory address, the conflict appears.

How to fix and prevent computer freezing problems:

1. Don’t use unknown software, CDs or pirated software to avoid virus infections which may lead to computer to freeze.

2. You should shutdown the computer using the button on startup menu always. Do not power off your computer to shutdown it directly.

4. If you need to run large-sized computer applications when you have run your computer for a long time or when your system resources are very slow, you will need to restart your computer first and then run those large-sized applications.

5. Try to avoid to use beta software so that you can maintain the computer smooth performance and prevent computer freezing problems.

6.  It is better to hide your system files so that you can reduce the chance to delete important system files which can cause computer to freeze if they are missing.

7. When you surf the internet, you’d better not open too many computer web pages at the same time so that you can reduce the system burden and avoid computer freezing issues. In addition, do not open links that you are not sure whether they are safe because those links may contain
malicious codes that can modify your system and cause computer to freeze up.
