Hey people, I have a weird problem. Its my friends laptop and I am.not familiar with it yet, so I can't give any specs. The laptop boots fine and is running good for a 7 year laptop. When we stream a movie and we watch half hour, the performance drops so badly, we have to turn off the laptop. Not even restarting will do the trick. The longer the laptop is switched off, the longer it will run good! Apparently, this is going on for a year or so. She brought it for repair a few times and the guys told her that the fan has to be cleaned. So they did and it went better for a while but the problem keeps coming back! I am not sure if this is enough info or not but thanks anyway for every tip!
