Extracting archives makes system unusable

Hi.

When I want to extract an archive (even small), the system becomes unusable. CPU goes up to 100%, Sound interrupts, everything lacks.

Well, I don't know where to start. Its an Acer Extensa 5220 with C2D T7100 as replacement CPU. I don't know, if this problem occured with the original CPU also, but I think i doesn't matter, because the new one is much more powerful.
Maybe its a speedstepping problem? During extraction it stucks at 800Mhz and doesn't step up to 1.8Ghz. Speedstep is set to "ondemand".

Some hints? Can provide more infos if needed.

Greetings

Perhaps, for some reason, you don't have DMA enabled on your hdd?

hdparm -d 1 /dev/(s|h)dX

Thanks. I've checked DMA for some time, it was enabled. This was the first thing, I've looked for 

edit: speedsteps works normal at programm-startups like OO

Re: Extracting archives makes system unusable

hm:

bash-3.2# hdparm -d 1 /dev/sda

/dev/sda4:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Inappropriate ioctl for device
 HDIO_GET_DMA failed: Inappropriate ioctl for device

same with sda 1-4

what does that means? DMA on or not?
