Most modern processors, and even moreso with laptop processors, are able to “protect” themselves by slowing down if they exceed a certain temperature threshhold. Since your computer is running fine until the moment the fan starts up, it just might be that the processor is running full speed until it hits a certain temperature, and then is “downshifting” because it is exceeding a temperature limit.

Another issue could be an electrical problem. Again, since the problem always happens when the fan kicks on, and you are also seeing a manifestation of the issue on your screen, there may be an issue with the power supply or wiring in the computer.
