Using the PS\2 keyboard, I selected Last Good Configuration and got in to my OS. From there, I restored to a day before I tried to automatically tune with the Nvidia program.
I also installed speedfan. Here are the temperatures:
It seems parts of my computer are overheating =/
I know that the GPU is the Graphics Card, but what's the Core?
What can I do? Upgrade power supply, get more fans (although I don't know if there's space), or get a new case?
What negative effects will result if I continue running my computer at this rate?
