OKay, so this morning I went to turn on my computer, when I did I heard this clicking sound. I thought okay, nothing big, but it kept clicking for about the three minutes I had the computer on. I could tell a slow down from it. Is my HDD dieing? It's a WD 40GB HDD, I bought it from a guy on another forums. This is the first time this happened. Do you think it still has warrenty? It was man. ON Feb. 23 2003. Do I need anything like proff of purchase to RMA it? PLease help! Edit: I'm on my computer right now, no problems at all like usual.
