You can try one of the following:
1) Make sure your BIOS is up to date.
2) Make sure you're running the latest version of that software.
3) Try other software online (from trusted sources)
4) Search to see if the manufacturer has their own monitor utilities.
5) Take the CPU fan off, the CPU off and clean the old thermal junk off with a moist (not wet, but moist) lint-free cloth or high quality paper towel, using 99% rubbing alcohol (not he 70% type). Re-apply with arctic silver 5 or some good quality thermal paste.
6) If you have no clue, your only option is to take the computer into a local repair shop, or try the manufacturer, or find a relative or friend who knows computers.
