I posted something about this in the Spyware section, to see if any spyware or viruses were causing this, but I'm assuming it's not since I didn't get a response and AVG and Spybot haven't detected anything.
The problem is, one of the fans, I'm assuming CPU fan, gets a bit louder when I load programs... which has never happened before. Generally, my fan is really quiet and will only get louder when I'm running over 50% CPU usage. Which, in this case, my CPU usage goes back and forth(unstable, I might add) 0%-5%, sometimes up to 20% depending on what I'm doing.
Say, when I go to check my DeviantART messages and open up two tabs from there, along with Meebo.com, Gmail, and Myspace open in tabs, the fan will spark up a little louder then get quiet again. Same thing when I load a few other sites.
My CPU temperature, according to SpeedFan is 33C, which is how it's always been. I've Defragged, used Disk Cleanup and CCleaner multiple times. I clean out my Temp and Recent Document folders everyday.
This began when I had to unplug everything while the room was having the carpet taken up. While it was unplugged, I took the opportunity to clean it and part of the inside. I didn't touch anything on the inside, I just blew some of the dust off with my mouth. I plugged it back up and started using, and then I noticed the fan noises occasionally and sometimes the Hard drives makes a noise when I use Disk Cleanup(which I've never heard the noise from it before, only on my External Hard drive when I add stuff). Could something be off-balance or crooked? That's the only thing I can come up with as to why it's louder, I mean, nothing else has happened and it didn't start until I plugged everything back up.
Oh, and to add another irritating problem, Firefox keeps getting script errors and needs to close. It happens usually on Myspace band sites, when they have many videos and pictures on their profile. Could I need to update one of the plug-ins, since I also get something about "The plug-in has performed an illegal action, it is strongly recommended you close and restart Firefox"(or similar)?
Thanks.
