Started around 3am, the video card's fan is making alot more noise than it ever did before. Its so loud it woke me up, and I shut off the computer. Started it up this morning and its just as loud, I can hear it from 2 rooms over. Card is a Radeon X800XL I've had it for a few years. Does this mean its time for a new card, or is there a way to troubleshoot the fan?
