I am facing GPU overheat problem. In idle it hits 110 degree C & within 2-3 min display is going off. I have MSI 5770 which is just over 3 years old. Now I have to run my PC without GPU. Any solution?

Should I go for a good thermal paste?

Today I apply the thermal paste, coolermaster one. But the idle temp is still 80 degree C & within an hour it rise upto 110, then again the display goes off. What could be the reason??
I clean the heatsink, fan & other stuff also.
