Photoshop Extremly Slow/Freezing

Can somebody help me with this situation, every time I start Photoshop I have to wait a half hour before I can start to work because it just wouldn’t budge, I mean it is extremely slow and freezing up on me, I think I have a decent computer (see Below) and enough memory (2 gig) and don’t see why it should act up on me?

Thank You Very Much
Mechel
