check all fans to see if there is a dust buildup on the blades. could be out of balance.
Hi everyone,
The fan in my PC has suddenly become very loud occasionally. When it does make noise, it very suddenly sounds like it is being overworked and moving much quicker than normal. My PC has always ran very quiet and this has never happened before. It seems to happen most frequently when I'm acting on webpages, like pulling up something on Youtube or looking at things on ebay.
Just now, all of a sudden, without doing anything besides writing this message, the fan just now started doing it again.
...still going... >_>
Ugh, done.
Each spurt of noisey-ness lasts about 30sec-1min and then it stops for a time. The intervals in between each episode are varied.
I haven't relocated my PC in several months and this problem just started occurring about a week ago.
Only one thing has changed in how I operate my machine in the last week, and that one thing is that my PC performed an auto update. I am now running Windows 8.1 vs Win8 I was using up until about a week ago.
Could this be the cause? And then, if it is probable, would anyone happen to know how I can downgrade back to my previous settings for free? I'm not trying to buy Win8 after updating unknowingly >_>
I've looked at some options only, but most seems higher level than necessary. Or at least I hope. I was considering a System Restore?
I'm looking for advice and suggestions Team! If we need some other info please let me know and I will provide.
My PC:

I'm running the stock model. No upgrades.
CPU Usage is pretty constant around 27-37%
