Dose anyone know ps1 emulator that will run on my laptop with a GMA X3100 graphics card?

ePSXe should work. It's largely Dependant on your CPU though, so as long as you're running 1.5ghz or over (any cpu of 1.5ghz should do, from a celeron to a C2D) you should be fine at modest resolutions of 1024x768.
