Well lately ive been noticing my computer has been making REAL loud noises... i can barely hear the tv sometimes lol. anyway does anyone know what is causing this and how i can fix it? also this has been happening a while but at random times a thing comes on my task bar and it has the look when a program is not responding on it but you cant click it or anything and there is no window for it. it disapears fast but what could it be or do i have to worry? ty.
