Simpel, dein Rechner ist einfach nicht leistungsstark genug.
Hier mal die offiziellen MINDESTanforderungen:

Processor (CPU):
3.0+ GHz Single Core CPU (Minimum)
2.4+ GHz Dual/Quad Core CPU (Recommended)

Memory (RAM):
1GB RAM (Minimum)
2GB RAM (Recommended)

Video Card: Direct X 9.0c compliant, Shader 3.0 enabled video card with 256MB RAM (NVIDIA 6600 or better/ATI X1300 or better) (Minimum)
Direct X 9.0c compliant, Shader 3.0 enabled video card with 512MB RAM (NVIDIA 7950 or better/ATI X1950 or better) (Recommended)

Zusammengefasst: Deine CPU ist unter dem Minimum, dein Ram ist am Minimum und deine Grafikkarte ist auch eher Richtung Minimum.

Hmmm...allein diese Angaben sollten dir deine Frage beantworten:

Processor: AMD Athlon(tm) 64 Processor 3200+, MMX, 3DNow, ~2.0GHz
Memory: 1024MB RAM
