I am running Windows 7 Professional (64 bit) and my computer crashes when I try to run the sensor test. Details: E8400 (not overclocked) My Idle temps are supposedly around 45-50c When I click sensor test it opens the box, I select Prime95 and let the test run. Everything seems to be going fine until the idle test when it says 'stopping Prime95'. At this point, my entire computer freezes, nothing on the display changes at all. Numbers stop changing, even the second hand on the windows clock gadget on the desktop stop, no a single pixel on my display will change. I have to use the hardware reset button on my computer and then everything boots normally. Why is this happening, and what can I do to fix it. I tried the 32 and 64 bit versions of Prime95, is there a 64 bit realtemp? P.S. I've heard around the internet that Tjmax for an E8400 is 100c, is this correct?
