If this is on a laptop, then often overheating can occur if ventilation is blocked into the case, especially when running tasks with heavy cpu/gpu loading. Run on a hard surface, such as a desk, rather than on carpet or bedspread. If system is tower case, then possibly dust is accumulating in the case blocking proper cooling to cpu or graphics devices. This is often the cause of overheating issues.

With a 10 year old CPU, its thermal paste may need replacing. It's a simple process if you have a desktop PC:

Safely shut down the PC
Unplug its power cord
Open the case
Take a picture of the heatsink, showing how it attaches to the motherboard
Remove the heatsink (which may have a fan attached; fan and heatsink are normally one unit)
Leave the CPU in place
Wipe away the old thermal paste from the CPU and heatsink with lint free cloth dampened with isopropyl alcohol
Apply new heat sink compound
Reattach the heatsink to the CPU
Close the case
Plug in, and power up
