I bought this graphics card for my HP Pavilion desktop (p6319f), Win 7 Pro.
It worked for a few months and then the fan on the graphics card started to vibrate and make grinding noises. This problem would come and go and kept getting worse. It got to a point where the fan would slow down to less than one turn per second and just spin very slowly and only hum quietly. If I allowed that to go on for even one minute, the game performance went down, the "frames per second" in StarCraft II would plummet to 5 or less. If I gently pressed the center of the fan with a pencil, it would stop and then start spinning at high speed. Sometimes that would fix the problem for a while and sometimes it would start vibrating again and slow down. Eventually it got so bad that tapping or pressing the fan would not help at all. It also seemed that turning the computer off for a couple of hours and turning it back on allowed the card to work for some time before failing. This method also stopped working eventually.
I contacted the manufacturer and sent it in. They claimed they could not reproduce the problem in their lab. They refused to replace the fan, even for a fee, and send my unit back to me, saying that my motherboard is the problem.
Is this possible that my motherboard could create the above conditions? I tried updating motherboard drivers and the card drivers with no improvement. Is the manufacturer right, or are they making this up?
