So I tried the Superposition benchmark test since that one is more recent, and it didn't crash at all. They told me that even though it uses OpenGL, SL most likely uses different scripting and programing and such. I might try the Heaven one you linked, just in case that somehow makes a difference.
I've also sent a email to my computer maker and am waiting on a response on that, so we shall see. I just have to say, though, thank you for trying to help, guys! I appreciate it, even if by the end of this, the problem doesn't get fixed.
