I dont know where to post this, so ill write this here. 2 weeks ago my laptop kept shutting itself down, saying "Problem 90D, overheating". I brought it to repair and they pulled out dust from my vents, fixing the problem. But not totally. The same day i brought it home did this problem. Its been a week and today the problem is showing as frequently as 2 weeks ago. I dont want to go and spend money again. I dont, really. What should i do?
