Hi all, I am trying to sort a problem with my system - so far with no luck. I have an ASUS A7V8X motherboard, AthlonXP 2600+ CPU and a Coolermaster "Heat Pipe" HHC-L61 cooler. Basically, the system won't stay powered up - it keeps shutting down but not on a time basis more on an activity basis. The system will sit in BIOS or DOS etc. forever but as soon as I give it some work to do (like installing Windows XP) it shuts down. The motherboard has ASUS COP (CPU Overheating Protection) so that if it thinks the CPU is in danger of overheating it will power down. Anyone had this? I've flashed the BIOS to v1012 and still no joy. The CPU temp is at 47degC at idle (from BIOS) and I don't know what it's getting to on load 'cos I can't get Windows on to load some software - is there another way? I need to be able to load up the CPU and monitor its temp from DOS. How do I check whether the CPU is overheating and the mobo is doing its job without windows? Is there some software anyone knows? The CPU cooler is on using the thermal grease that came with it. Is a thermal pad better? Could it be that my CPU's overheating (I've tried 2, a AthlonXP2000+ and this 2600+). Any help would be great 'cos I'm going crazy over this!!
