video driver infinite loop error, vpu recover

Hello

Since two weeks im having issues with my video card, who apparently got problems concerning the driver. Some minutes after launching win XP a blue screen appears and says that the video driver has gone througha infinite loop. Sometimes before this happens my ati control panel says VPU recover has avoided system crash and restart.
I took a look in my DXDIAG and it show under "AGP acceleration: not avaible"..why?
In my bios I cant set the agp aperture size. No line about AGP setting in either basic and advanced bios features.
I wish somone can help me out.

Here my dxdiag text:
