Download Speccy and verify your temperatures

If showing 70 degrees plus. Post your temps and wait for advice.
Meanwhile check for dust build up in the fins of your CPU heatsink...

u might need to replace the thermal paste at heat sink....
if cleaning the dust do not help....

First thing I'd do is open the case and have a look to see how dusty it is inside.

Clean it out if it's excessive. That may fix the problem.
