I'm trying to fix an older computer that all of a sudden decided not to boot up. Here's the deal: I turn it on, the power-on LED lights up, fans power-up, but that's it. Also, a constant clicking noise is coming from somewhere, but I have no idea where. My initial thought was the HDD, but it still clicks when I disconnect or replace it. Then I thought maybe the CD drives, but they also aren't the problem. After searching online, I was led to the PSU, but after replacing that I get the same problem. I also thought maybe the cpu fan was the cause of the clicking, but I briefly powered-up w/o the fan connected and it still clicked. I was finding some mention of beep codes online, but this is more of a click than that annoying, loud beep. It doesn't seem that the clicking noise is coming from the speaker.
Also, I've troubleshooted as much as possible. Reseated all connectors, no burn marks anywhere, etc. I'm at a loss. Any ideas? Thanks,
