Hey there. I built my PC a little under a year ago. Everything has been working perfectly until yesterday. All of the sudden, my graphics card's fan has been crazy loud. Like, its not a "fan running faster that usual" loud. It sounds like its having issues running as the sound also sometimes fluctuates/throbs , if you know what I mean. At first, I could get it to stop by rocking my PC back and forth once or twice, and another time I did it on accident when I started to move the PC to get ready to open it. I took out the card and got rid of as much dust as I could. It worked fine again for about 8 hours, then it started up again. I've been reading on the internet where people are having the same problems and had to replace the fan. I'm hoping I don't have to do that as there doesn't seem to be a way to even open the graphics card up. Here's a link to a video I recorded to show people the sound: youtube[dot]com/watch?v=VHeqK8Z_x_E It's a Radeon HD 5850. The noise is seriously getting irritating as I can't even use the computer without it making noises. Not to mention that I'm worried I'll have to spend a lot of money to take care of the issue. FYI, I'm not very hardware savvy.
