Sanddrag,
Don't take any chances, the power supply should not be that low. I might not trust the monitor so I would get in there with a meter but since both of the negative supplies are low, you are about to cause some disk overwrites that you may not recover from. I would, disconnect the drive, power on and measure the motherboard input connector while connected to the board. If it reads the same as the monitor within a few tenths of a volt then the supply is toast. Replacements are pretty cheap, like about $50. If you are lucky enough to live near a FRY they are probably cheapest. You can try MCM or a computer mail order for replacement in your case style. Don't wait!
