It started all of a sudden last night, upon awakening the computer. My PC is right around 3 years old.
I'm pretty sure it's the fan on my video card. I don't play video games anymore [altho I couldn't resist checking out that online Wolfenstein thing and playing that for a while one night] so this one is just the mid to low end of nVidia's "business graphics" line of cards. (So maybe I don't even need the fan?)
I vacuumed it out as best as I could with what I've got (large extension on a huge Hoover), but no change. It wouldn't be so aggravating it if was at least constant in its new loudness.
Anyone reading this know if this can be fixed? Should I go buy some compressed air and try it? Or is it probably just some (cheap) bearing(s) going out? I had a new fan noise in my computer about a year ago, but it was just a dust bunny in the CPU fan I think, and it stopped making noise once I sucked it out.
Is there a way to re-lube these things (that's not going to end up dripping oil on the rest of my system/scattering graphite dust when in place!)? I could take the card out and take it into the Geek Squad or something, if the labor charged was not near what a new card costed.
