Phantasy Star Portable 2

[tesla100]

I've tried changing my character's race THREE times and each time the game just freezes, then everything on the computer locks up and I can't do anything. I've had to hard reset the damn thing multiple times because of it. This isn't even my computer, so if it breaks I'll be in a lot of trouble.

Specs:
Windows 7 Home Premium 64-bit 4GB RAM
Intel Core i3-21 CPU @ 3.30GHz
AMD RADEON HD 6450

It's frustrating because Persona 3 Portable runs fine. But whenever I get into PSP2, it just causes the entire computer to stop working.
