Looking for easy computer speed up solution?

My computer seems to randomly shut down when I am in the middle of things. I have tried several times to see if that could tell me anything. It seems that the computer will shut off at random. What could be wrong inside of the machine?

One of my friends suggested me a site "Sisytek.com", where I have got the solution all of my problems in short period of time.
Thanks...

First, you should check the reasons to make your computer slow down, please refer to the following list:

1. Low-performance hardware

2. High-data consumption

3. Insufficient RAM

4. Exceeded Memory usage

Second, you can take the following ways to speed up your PC:

1. stop all unneeded background processes

2. uninstall all applications that are no longer used

3. install anti-virus software and keep it current such as AVG, Avast and so on.

4. Using free third party software such as Wise Care 365 from http://www.wisecleaner.com/wise-care-365.html

5. Consider re-installing windows

6. check the temperature of your computer
