PSU -12 and -5 rail problem?

[Luv2DriveTT]

Below is my power supply reading from Sysoft Sandra. My PSU is a Antec Thermalake 430, but since I've been getting frequent unexplainable crashes I'm beginning to look at everything as being a possible cause. I was surprised to see the readings for the -12 and -5 rails, is this normal?
