How does HIV/AIDS actually kill people?

What's the process to an individual's death by HIV/AIDS?
gpt
HIV preferentially infects a type of cell called a CD4+ T-cell. These cells are commonly referred to as Helper T-cells and are crucial during infection to help stimulate various arms of the immune system. 

When someone is infected with HIV CD4+ T-cells are systematically infected and killed by HIV. This eventually leaves the body with little to (in extreme cases) no detectable levels of CD4+ T-cells. This is when the patient is officially diagnosed with AIDS and like the other commenter stated dies from things like the common cold and extremely rare forms of cancer and pneumonia.
