So recently i've been having some computer freezes when trying to play any game I have and also just simply browsing the web but this takes way longer to get the freeze, at first it would freeze and the speakers would make a screeching noise, I took apart the case and saw I had my fans ran wrong so I changed them to the right direction so now I still get the freeze but no screeching noise, I can play a game longer since I changed the fans but still getting a freeze, I took the computer to bestbuy and they ran their full stress test on it and said it passed with no problem. I thought maybe overheating? Any suggestions on what I should do?
