Thanks ChainsawAsh, I'm glad you're still willing to answer my technical questions. Right now my PC is an AMD Althon 64 2.2GHz processor with 2GB of ram. My video card is an XFX 7800GT 256MB of RAM. Pretty modest by todays standards, but it was considered pretty good back in late '05. It happens randomly, it doesn't keep happening at the same spot. I tried turning off my antivirus software and having no applications running in the backround, but it still does it. I think I will get a quad core processor with 16GB of ram, maybe even 32 in my new build.
