Hello Tom's Hardware community, I need help from you! Recently I got a problem that at random time, most of the applications won't work. Actually when I open some sort of video, like youtube it won't start but loads, then when I try to play song at from pc any media player won't work, and at that time a lot of applications won't work, games, other program, except a internet sites without video player. I don't know if that is related to that video or it's just problem with my computer. It fixes only way when i restart my computer. Please, help me best as you can, and you have my thanks ahead.
