... grab yourself a Xigmatek cpu cooler or something while your at it too, and more thermal paste. Use 91% alcohol and qtips to clean the old paste off the cpu and heatsink. Use about a pea sized dot in the center of the cpu and use the new heatsinks downward pressure will spread it accordingly..

Your computer is severely overheating, close to the point of permanent hardware damage or failure if you keep trying to run it in its current state. You
NEED a better CPU cooler, and some good thermal paste. Here are some links to things you need.
Low cost, but effective CPU cooler. I have used these on a couple builds for other people with positive results. Others may differ with this decision and I welcome other ideas to help this guy, as I have not used this on an Intel set up.

Also, take into consideration that with air cooling products, your case needs to have proper airflow coming in, and ventilation coming out. Make sure you have at least 2 fans bringing cool air in, and a top and rear fan bringing air out. This is a minimum amount to properly regulate temperature and ventilation. Regularly cleaning the dust out of your computer is essentials. You can use canned air to do this, or a power duster.
