Check windows device manager under "system" in the control panel for any conflicts. You may also have to remove the motherboard and flip it over to see if the heatsink for the i3 is installed properly. Coretemp may also give you some cpu readings. Other possibility is a video driver problem if the freeze ups occur mostly while gaming. But a temperature issue is your most likely problem.
