HWmonitor and Prime95. = HWMonitor opened and running where it can log temps and volts min/max. While HWMonitor is running you can begin Prime 95 Blend mode. Run for a minimum of 20mins so we get a ballpark of what is going on.
Capture the HWMonitor showing Min/Max of Cpu Temps, Core Temps and of course the voltages at the top of the HWMonitor menus. Don't care about HDD temps or GPU or the rest of that stuff.
You can use the Win 7 snipping tool to capture 'only' the menu we need and not the entire screen. We also need the CPUz showing the CPU TAB, the Memory Tab and the SPD tab located across the top of CPUz. Those three captures of CPUz and of HWMonitor will clue us in to what is happening at your end which we are not able to see otherwise. Thank you.
