Re: GPU at 97C and Core at 62C
It is likely filled with dust. What are you using to monitor temps?
If you are not comfortable opening up the laptop and using compressed air to clean the heat sinks/fans (toothbrush works good to clean caked on gunk), then take it to your local computer shop.
If you do feel comfortable, be sure to touch a metal part of the case away from components after opening and before cleaning to avoid electrostatic discharge.
