The two may seem the same but they are different from each other.
A crash is when the computer can’t process the user’s request and it shuts down or restarts or may shows the Blue Screen of Death. A freeze is the state when the user is trying to do too many things at once and the computer can’t keep up with the requests, it cannot read the file because it is confused. These are common problems of the Windows 7 operating system. Many people are experiencing these problems on their Desktop or Laptops.

These problems may sometimes go very to serious, that it may distroy your important data and even sometimes distroys your whole Pc. However, in most of the cases, they are only mild causes as the symptoms aren’t that serious.

The causes of Windows 7 crashing are as follows:

1. Specific files are not readable.
2. Files have been corrupted or may damaged.
3. The registry settings are unstable and have some issues.
4. Recently changed hardware or may cause from new hardware.
The causes above contribute to Windows 7 for becoming an unreliable and unstable system. These problems can be fixed by following some of the steps that I’ve described below. I am going to explain you how to repair and prevent Windows 7 from crashing in the future.
1. The first thing you should do is to access the ‘Startup Manager‘. When we turn on our computers, the Startup Manager comes up and has a list of programs and processes that need to be loaded up during the Boot process.
2. Having too many programs and processes during the boot process can make the computer very slow. It is important that you minimize the number of programs and processes that are requested during the boot process.
3. To do this simply Click on Start > >Run >> type msconfig and press Enter.
4. Select Startup from the tabs and disable some programs and processes from the list.
5. The second thing you should then proceed is to remove unnecessary programs from your system as this can clog up the computer’s memory. To remove any unwanted programs from your system, Click on Start >> Control Panel >> Uninstall A Program. Then proceed to remove any programs that you think might be useless.
6. After that, it is necessary that you perform an Anti-Virus scan of your entire system. This ensures that your computer has not been infected with any sort of Virus or Trojan.
7. Execute a scan of the Registry using a registry cleaner. The Registry Cleaner will scan your entire computer and locate any erratic files that are causing your system to fail.
