Pcsx2 & gt3

hey, i have a small problem with PCSX2, GT3 starts and runs fine to the point where i enter a race / licence.
example, i get all the way to where im about to press race at a licence, then, before i do that, it starts to go really slow and freeze, then i get a error message and PCSX2 shuts down. oO

PC specs:
Motherboard: Asus M2N32-SLI Deluxe
Ram: 2 gb cant renember the speed, but it was the highest speed the motherboard did support
Video Card: GeForce 8600 GTS
CPU: Amd Atlon x2 5600+ (2.8 ghz)

i run GT3 from a image, mounted in deamon tools, made from my own gt3 cd, so i guess my dvdrom can read ps2 games.

Edit: im using GSdx9 (MSVC 14.00, SSE2) 0.10.0 graphics plugin, windowed.
gigaherz's CDVD Plugin 0.7.0.

ask if ya need more info.
