Whenever I try opening my computer properties (Right click computer> Properties) the window opens but then freezes and windows explorer crashes before I can do anything. I've tried all means of getting to it like using run and searching wei in the start menu but they all end the same way. I've also tried using the system scan on cmd prompt which didnt fix anything. Also, i dont know if this has anything to do with it but i am also unable to open videos, the same thing happens but with windows media player and pictures just do nothing when i click on them. (If they arent related i will open a new thread for it). I have an HP Pavilion g7.
