If Windows 7 is running slow, there are likely a number of different reasons for this issue occurring. Unfortunately, many people point the finger at damaged or corrupted hardware for the problem - citing that this system requires a "large capacity of system resources" in order to work correctly. The good news is that although Windows 7 does need to run on a PC that's at least 3 years old, there are a number of easily curable problems that are more likely to be causing the slow speed. Most of the time, software problems are the cause of a slow Windows 7 system - making it essential that you're able to clean out any of the possible problems that are causing your system to run slower. This means that you can use software programs to speed up your system properly.
