Problems: I bought my dell studio 1557 (Blu-ray drive player for studio 1557 / DVD Burner for Studio 1557 ) one years ago. A bit of days ago, When I playing or doing something that requires the power of the graphics card it starts raising its temperature and programs like Everest or MSI afterburner shows the graphics card working at 100ºC. I think this is risky for the laptop but that is not all. When the graphics card works at this temperature I cant play flawlessly because the graphic card starts throttling and this is very annoying.

Solutions: the solution doesn't involve buying a new power supply, because the BIOS in the computer won't recognize the additional power, and will continue to throttle the system down. what you may want to do is disconnect the computer from the power supply and run it off battery, to see whether the problems continue.
