Hey guys, here in Memphis today the weather hasn't been too good - lightning, winds, etc. So I decided to unplug my PC in case of lighting or something similar (I've had a PC fried because of this). Well, right now it's calmed down a bit so I decided to turn on my comp. When I turn it on, I hear this really weird, low humming noise as opposed to the usual high pitched whir. It hasn't ever done this before. Also, since it happened (about 10 minutes ago) it hasn't done it since. Any suggestions on what this might be?
