CPU core throttling

I keep getting throttle problems

 

Where an app goes slow and then speeds up to double and then goes slow again.

 

I noticed it mostly happens when Anti-Virus and MS-Defrag are running, but it also happens at other times when no background stuff is running.

 

In my animated programs i had to put timing / loop-counters in to control the pulsing, like below.

[code]

 

Do

    time1=timer

 

  (   program stuff here  )

 

    time2=timer

   

    'get fastest loop time the computer does.

    if time_min = 0 then time_min = time2-time1

    if time2-time1 < time_min then time_min = time2-time1

    if time2-time1 > time_max then time_max = time2-time1

    time_avg = (time_min+time_max)/2

    time3 += time_avg

    loop_count+=1

   

    'get number of loops in quater second.

    if time3>=.25 then

        for a as integer = 1 to number_of_balls

            balls(a).speed = ( (balls(a).radius*2) / (loop_count) ) ' change radius*?? to adjust speed

        next

        loop_count=0

        time3=0

    end if

 

Loop Until Inkey <> ""

 

[/code]

I use FreeBasic for doing my programs.

 

I've got my power options set to "max power usage" when plugged in, and still i'm getting throttle pulsing problems.

 

I've got a Compaq Presario CQ60-210 US Notebook PC

AMD Athlon X2 64 ,  Running Windows 7 64 bit with 4 Gig of Ram.

 

Is there a know problem with other people reporting throttle pulsing ??
