I am fixing a computer for a client and I just can't find a solution to this. Someone please impress me by showing off their imminse knowledge. A computer I am working on has cpu usages or 100 percent; almost all the time. I have got all the lateest drivers and chipset drivers and have checked all the parts. It has windows xp on it. Its a AMD 1700 athlon xp. Thanks for all of your help!
