Hello everyone, for some reason when I turn on my computer everything is ok. But after one to three hours, a buzzing noise occurs. This noise is getting worse and worse as time passes. Only when I restart the computer the problem is solved for the next couple of hours and this problem happens over and over again. I don't know what can have caused that. I think it's a driver problem but I have updated and even reinstalled the drivers and the problem doesn't fix. Somebody, please help me.
