pc keeps crashing while installing particullar software

When I install curtain software after initializing the install my PC crashes lines appear on my screen (all of the screen is covered in them, always horizontally) and loops a very high pitch sound, I've so far had this problem with shadow of mordor and more recently heroes of the storm, in the main time I've replaced my hard drive (with the same model: western digital green 2tb).
Further my specs are:

AMD Phenom II x4 955 processor with 3.20GHz
AMD Rradeon HD 6700 Series
I don't exactly know what my power unit is called but its a cooler master
I'm running windows 7 professional 64 bit

I know there's another thread with almost exactly the same problem but there is no real answer for me there, hope you guys can help me out.

  1. O and it goes to the blue screen of death and then restarts itself, I've let my machine cool down multiple times and it still crashes
  2. so I fixed the problem by ending all memory heavy tasks and limiting my download speed to about 7 MB/s, which worked I guess my pc is just not keeping up with my download speed
