My desktop is a 3-year-old Dell Dimension 8400. It was high-end at the time it was bought, but regardless is starting to show its age. I have upgraded some of its parts since then to keep playing World of Warcraft bearable, but of course it will need to be replaced eventually.I have had my share of computer problems with my current computer (not suggesting that Dell is necessarily a poor computer assembler, mind you). Other than high school computing studies, I have had no formal training in maintaining a computer, so I usually need to end up experimenting when something goes wrong. Without further ado...
The Problem:
I had upgraded the video card (to an NVIDIA GeForce 8400 GS). After its installation, the computer tower would emit a noticeable low-pitch rattling sound. It was easily recognised as percussion and distinct from beeps emitted from the system speaker.
