Smile can you tell us more about your computer? How much RAM does it have? Is it dual core or quad core? Intel or AMD? What cpu do you have ? What is the wattage of your power supply? Do you use file cleaners and registry cleaners? Do you use spy-ware, ad-ware, mal-ware cleaners? Do you defragment daily or weekly? Do you do a msconfig and shut down processes at startup that need not be running?
Do you reapply silver compound on the cpu where the heat sink goes? Do you reinstall windows once or twice a year as needed? These and many more items are additional items to think about in addition to the heat problems. Reapplying silver compound could help the cpu from getting so hot also.
