I have a Gateway, not sure what exact model, it's from 2003.

Anyways, late last night while I was away from the computer, it suddenly started making a really loud whirring noise. I immediately ran in an cut the power, fearing it was on fire or something. After removing the cover and seeing nothing really out of the ordinary, I turned it back on, but it made the loud noise again.

Then, when I turned it on today, the noise was gone.

From what I have concluded, the noise appears to be coming from this box.


Now I have almost no knowledge of Computer hardware whatsoever. Most of my knowledge is of software.

So can anyone give me any help here?

What is that box? What does it do? Can it be fixed?
Replaced? Manually? Cost?

Any help would be greatly appreciated. Thanks.

That" box" is the fan and heatsink for the CPU
You're going to have to look at the back of the computer to get the model number to purchase a replacement
Cleaning the heatsink might get you by, but it might also be failing bearings in the fan
Ignoring it and letting it go can damage the computer in a big way
