I have just witnessed something strange in MBM5 with my psu

+3.3 = 3.09V
+5 = 4.97V
+12 = 1.55V
-12 = -170.75V
-5 = -5.20V

are the +12 and -12 readings normal because i'm getting random reboots and blue screens recently and i was wondering if it was the powersupply

Your computer wouldn't run for very long with the 12V at 1.55V, so my guess is that MBM5 is smokin' crack. Do you have a voltmeter or multimeter that you could use to do a reality check?

Bigger picture: what brand/model of power supply, and what's your hardware specs including all drives and cards?

MBM5 has its limitations .... it doesn't read ALL mobos correctly. Its great if its accurate for your board. But in your case, I guarantee its not. Try your mobo site for monitoring software if you're not comfortable probing your connections with a multimeter. Although, thats the only way to be positive your readings are accurate.
