I have a Lenovo Laptop G780 Model 2182 that has recently started running VERY slowly.
It all started when I noticed that it was making a very strange noise and I turned it off (it had been on for some time - days). The next time I booted up it took an inordinately long time, and then when I tried connecting to the internet it froze up (or was also taking a LONG time). I should note that my wife had put a dehumidifier in the room with the computers and I just noticed that there was a fine white dust on the bottom side of the laptop.
I have run a complete virus scan which came back clean, and rebooted. No luck.
Is it possible that the fan was damaged from mineral dust accumulation? I have heard that a bad fan can cause the CPU to stop intermittently to keep from overheating.
Any help or suggestions would be appreciated.

I have exactly the same problem it had a clicking sound but that is gone.
I found my fan was cloged but even though I did a very good cleaning it still takes two hour just to log on and even ther i can not open anything.
