why won't my computer run Halo

[jjp13]

I have pentium 4 1.6 gigahertz, 128mb Sdram, 40 gb hard drive, and a geforce4ti 4400 128mb graphics card. My computer still runs halo slow. Do I need more memory or is it something else?

Memory is definitely your weak spot there. Plus you could get a processor over 2+ ghz
