There may be many reasons for your computer to freeze often and disturb you when you are working seriously. The reasons could be as follows:
Your system may be having a virus, which is slowing down the performance. The computer may not have the sources which are required to work properly. The hardware compatibility with the computer might not be proper. The configuration of the system may not allow you to open a particular application. The software may not be compatible with the computer. There is a chance of the page file being stuck in the cache for some time. The memory space required may not be there.
Check whether the computer has a virus by running a reliable anti virus application. This will help you know if there is any virus and delete it. You need to keep updating your anti virus software to prevent any new virus from entering your computer. The update can be done using the website of the manufacturer.
Your system might also be affected with spyware and adware. A spyware removal tool can be used to remove spyware. This tool is available on net or in the local software shop.
Your system may not have the correct configuration required to run the software. So, delete all the software installed recently to see whether they caused the problem. If your system still freezes, it is not the problem with the software and you can reinstall them.
Sometimes, the RAM may have defects causing the system to freeze. A memory check can be done using the software available on net. Keep your CPU cool so that the computer does not freeze; keep some memory space free in the system to run it properly; and also keep updating the system.
