wasted 6 hours looking for help

[Inferno]

here's what my computer has

AMD turion64 X2 dual-core mobile tl-60 2.00GHz
2Gb of ram
vista home premium 32bit operating system
ATI radeon X1200 graphics

So I have openGL support.
directX 10
Vc++ has been updated.

I have dolphin SVN R 3661

this is the problem:
I can't get it to run when I open a iso file. the screen will turn gray and then an alert come on saying the dolpnin has stopped working...windows is searching for a problem. and then it closes.

I have tried it on Soul Calibur2 and Super Smash Bros Melee with and without dual core on and with openGL and directX

when it's directX i get a black screen with yellow text. an alert comes on saying posmtx streem not supported correctly.
