voltage problems?

[dmw16]

My computer just rebooted outta the blue. I dont know what happened, it just rebooted. So i fired up motherboard monitor to check my voltages. I am not sure exactly what I'm looking at and how things should read. So hopefully someone here can help. Here are the readings:

label: readout

+3.3: 1.54V
+5.00: 4.19V
+12.00: 12.04V
-12.00: 1.71V
-5.00: 0.89V

is my PS going?
thanks,

ps. my power supply is a 300W antec. I have 512MB of RAM, XP1800, 2 optical drives, 2 hard drives, and a GF4

looks like your PS is going south......the voltage rails are horribly low

that is what it looked like to me too. I was worried that was what was happening. You don't suppose that could be related to my monitor acting funny, do you? Flickering and stuff? Perhaps low voltage in my video card?
thanks,
