motherboard agp problems?

[lytri]

I have an Abit VT6X4 motherboard and have tried both a creativelabs tnt2ultra and msi geforce2 pro in my agp slot. the agp version on the mobo is 2.0. i have a problem where whenever i play games, after a certain period of time it will lock up. i have a feeling it has to do with directx/mobo agp and some conflict with my video card. i've set my agp aperture to 32 and 16 and it still happens. don't know what to do anymore. i've installed via's 4in1 drivers, using detonator 12 (latest official) drivers for both vid cards. any help would be much appreciated, as this is driving me nuts.

System specs are:
Abit VT6X4 Motherboard
SoundBlaster Live Value
Acer CDRW 8432
IBM 22gig IDE HD
MSI GeForce2 Pro
