That is a fairly old system, try cleaning the heatsink and fans(s), apply new thermal paste and see how things run. Try a clean Windows setup to rule out any software issues, there should be a recovery partition on the system to set it back to new setup. Just make sure your files and programs are backed up and you can re-install things.

First thing is to clean out any dust. If that does not fix everything then spend time reinstalling/troubleshooting
