Recently, my computer has begun making louder fan noises than usual. I opened my computer to see if there was anything obvious affecting the fan (e.g., dust), but I didn't see anything. I did some research and downloaded a program called SpeedFan, but to be honest, I have no clue how to interpret these readings:
I've also been having another potentially related problem. Occasionally, when I try to wake my computer from sleep, there is no response (and the reset button doesn't work), and I need to disconnect power. Upon restarting, it says, "Overclocking failed." To the extent of my knowledge, I haven't ever overclocked my computer. (The computer works fine after that error message is shown.)
Can anyone shed some light on what's wrong?
