so i got this card: Sapphire radeon 6770.
before christmas it started to make some not so loud sounds, so i saw it was from the fan. then i left my house for like 3 weeks. when i came back, the noise still existed. one day it stopped, so did the fan. i maxed the fan speed, but it barely moves with some noise and the whole card is kinda shaking. i did NOT do anything. Maybe its dust or something. Any ideas what is it and what should i do? Thank you in advance
