Question
When I start or restart my computer the fans are really loud.
Answer
This is normal behavior for many computers. Many computers have the ability to increase or decrease the speed of the fans installed in them and when first turning on the computer or when restarting they'll be at their fastest speed to help keep everything cool.
After a few seconds the fans should go back to their normal speed and cause the computer to be quiet again. If the fans stay loud you may have an issue with one or more of the fans in the computer.
