>HDD light blinking? That means it's working correctly. Am I right?
In a lot of ways that is correct. Generally, when something is thrashing the hard drive it is making actual progress on its task, and its task is relativly short lived. This means that if your computer is going slowly, and the HDD LED is active, you can likely wait for the HDD LED to quiet down. In contrast, when your computer is going slowly (or not responding at all) and your HDD LED is off, it is much more likely that something is wrong and won't resolve itself.
