PS2 Emulator Help!

For some reason PCSX2 keeps on making the graphics of the games I play have these weird Vertical looking stripes.. I can't think of any solution to fix this (note: I've tried using the ZeroGS thing, but it makes it run super slower and the sound begins to break and crack and echo.)

My specs:

OS: WinXP Pro

CPU: Core 2 Quad Q8200

RAM: 2 GB RAM

GPU: GeForce 9800 GT 1 GB

Edit: Also, does anyone know how to make the frames much higher and the game run smoother (as in no lags in the talking parts and etc.)

note: I'm playing P4.

I think the PS2 emu needs really high specs... or... wrong plug-in or setting?

I think it's the settings. Since I can run games like Crysis at such leisurely FPS (as in silky smooth)

It's your RAM. Some games need at least 6GB of RAM before running smoothly.

Try using the speed hacks.....

It should increase the fps......
