I installed Motherboard Monitor, and as soon as I told it to start monitoring my CPU and System temperatures, it displayed the temperatures at over 200 degrees. I thought it was spitting out erroneous information until things started to go haywire. I noticed that System.exe was using 100% of my CPU. I shut down MBM, but the System.exe process wasn't released, so I was forced to reboot. I had the MBM update interval set at 15 seconds. I then went into my BIOS and set it to shut down my system if my CPU temperature climbed over 167 degrees F. I started MGM again, and a couple of minutes after it started reading my temps, my system shut itself down due to the CPU overheating. I uninstalled MBM, and installed CPUCool, hoping it would perform better. No luck. When I double-click the CPUCool shortcut, I don't see anything, but the CPUCool.exe process starts up and shortly after that, my CPU overheats. Both of these programs end up looping and seriously over-taxing my CPU. I know a lot of you are running these programs successfully, so I'm wondering if you can tell me why my system is overloading. It's an Abit TH7II motherboard with a P4 1.5G chip and 512MB of RDRAM. WinXP Pro. Thanks.
