Hi, for the last few months, I have been having problems with my Compaq Presario S6300NX computer. It has been freezing all the time lately, and I believe it is the CPU fan not working corectly. I recently installed PC Wizard, and it said that the processor temperature was about 70 degrees celsius. I have ruled out other possibilities for freezing, such as memory, and viruses. This is the only possibility left. I wanna know if I should get a new fan, apply new thermal paste, or do both. Thank You.
