Last month I bought a computer online that's delivered already built, and just recently the power supply has begun making a quick ticking sound. I'm unsure if it's the fan or something else, but the ticking sound doesn't start until I'm at my desktop. During boot it's quiet. Anyway, it's just impossible for me to work at my computer with this ticking going on, and I can't get into the thing to take a closer look without tearing the sticker that voids the warranty, so my question here is if the warranty covers these problems and what I could do if it is covered? Thanks. p.s. In case it's relevant info, my computer turns itself on from shutdown within minutes to hours after being shut down. I've done as much google troubleshooting as I could on this problem. I don't believe there are any tasks that are waking it from its slumber, and the BIOS has wake on lan disabled, so all I could do to work around the problem is to pull the plug each time it's shut down.
