When I started the new system, everything came up, I got into the Windows desktop, but there was a constant clicking noise in the case on the side where the DVD, FDD and HDD are. It's not the clicking of a HDD being accessed. This noise wasn't there before I replaced the above components. I unplugged the power to the DVDs and FDD and the clicking continued.
I will unplug the HDD to see if the clicking is related to it. I also plan to swap to the old PSU tonight to see if it's related to the PSU. If that doesn't help, I'll use my old mobo and see if it's related to it.
Any other suggestions or thought on what could be causing this clicking noise?
It's on all the time. My cooler is a Zalman CNPS10x Extreme, and I've heard it has something to do with the PWM part of the fan... It's definitely a lot quieter now though than it was before. Maybe just some parts are now ground down a bit... who knows. Some G35 headphones were the early solution to my problem lol.
I unplugged the 2 DVDs from the ribbon cable as well as the FDD and the clicking stopped. It turned out that it was the FDD. Just plugging the ribbon cable into it caused it to click. Apparently I didn't make all of the connections correctly. When I reviewed the connections and plugged it all in properly, the clicking went away.
