...out please help!!? here are my specs-amd athlon xp 1600 (over clocked at 115mmhz now speed is at 1.44ghz)-768 ram (DDR1)-windows xp sp2-nvdia geforce 256mb-40g maxtor-500w PSUi cant trace where the problem started, whether i added a new hardware etc. even if the processor speed is not over clocked, the results are still the same. the CPU usage just jumps wildly! it even stays at 100%, i tried everything, i replaced the video card 2 times, changed the processor. formatted the hardisk, yet still the same... im having doubts about my mother board though... i just need a second opinion on this. thanks
