Indestructable Dll Files

[Almostmini]

Hey Guys.

I'm having some trouble getting a decent FPS count from a 9800GT on a 7 year old game called IL2 1946. It runs ingame at about 5FPS which is appalling, i know that one contribuary factor is my sound. When sound is all off which is done in the device manager it gets up to about 40FPS.
Another problem i have noticed is the existance of some ATI files in my Windows system 32 folder.
They will not go away. I click, i delete, and they reappear!

The file names are.

ati2cqag.dll
ati2dvag.dll
ati3d1ag.dll
ati3daag.dll
ativvaxx.dll
ati2.mfag.sys

I would really like to get rid of them so that i can eliminate them as a possible cause of my poor experience.

Thanks a lot
Mini.

OS is XP

I used to run the game on an ATI X1300. Now am running a Nvidia 9800 GT.
The 1300 ran it at a decent rate and it wa splayable. perhaps a compatability issue between Nvidia cards and these sound drivers?
