Blender Crashing Nearly every five minutes

Hey, everyone, I am working on unwrapping a head in blender 2.57 and the program is crashing on me like every five minutes. Its becoming extremely frustrating because sometimes I am just trying to save the work I have done in five minutes and then it crashes and I lose the data. Does anyone know what might be the problem?


We’re going to need much more information to give any sort of accurate feedback.

Is there something specific you’re doing when it crashes? What operating system are you using? What type of video card do you have? Does this happen on other .blend files?
