I have the same sound on my Xonar DX, Asus uses relays to switch from the rear header and the front panel. When the OS starts up, the relays energize, creating that "click noise".
@OP , Filling in your system info could potentially give us a better picture as to what could be causing this. If your system is watercooled, I have to believe that you, or whomever set up the system, knows what they are doing. Even if they didnt, Intel uses thermal throttling to prevent overheating, and will shutdown the computer if it gets over the specified threshold.
What your describing sounds like a failing power supply, or potentially a power supply over current protection circuit activating. Another possibility is you have a leaking capacitor, or a short somewhere between the motherboard tray and the and the motherboard (if you didnt use stand-offs).
There are numerous potential causes of what your describing, the ones above are the less common ones. The most common one is an unstable overclocking, on this forum at least. You stated that you have already reset the bios to the defaults, however, did you remember to set the ram voltage to the manufacturers specified value after resetting the bios?
Ive seen insufficient ram voltage cause all sorts of instability issues within windows, and even before it gets into windows, random restarts being one of the symptoms. This is most common when the motherboard defaults to the minimum spec voltage for that specific type of ram. When using high performance ram, the voltage is usually a bit higher than that minimum default, and causes instability if the value is not reset.
Let us know if you have found anything, fill in your system specs, and good luck!
EDIT: In your bios, there should be a hardware monitor, that will tell you temps, voltages and fan rpm's. If your CPU is running hot, it should tell you there, just a heads up.Edited by Mattb2e - 1/11/11 at 7:57pm
