Saphire radeon HD 5830 1gb edition

well, system idle process is the only thing i can see that is a possible culprit, it also fluctuates as the cpu usage goes up, i think i've found the problem, so how do i fix it?

System idle process is a normal process....it runs whenever the OS has nothing to run on the CPU:) probably a continuous NOP cycle:)

Most probably ur CPU is too slow for ur workload....and u have some CPU intensive app running in the background....possibly a heavy antivirus or such:)

Lol, i run Win7 professional smoothly with only 2GB RAM :D

Yup, a virus could also be the cause of periodic usage spikes :)
