Unhappy Sensors Alarms, Computer Crashing

Hello everyone,

Does anyone know what could be causing me to get crashes and massively bad lm_sensors data? Here is the output:
[~] sensors
Adapter: ISA adapter
VCore 1: +1.58 V (min = +1.42 V, max = +1.57 V) ALARM
VCore 2: +2.53 V (min = +2.40 V, max = +2.61 V)
+3.3V: +4.86 V (min = +3.14 V, max = +3.46 V) ALARM
+5V: +2.37 V (min = +4.76 V, max = +5.24 V) ALARM
+12V: +3.90 V (min = +11.39 V, max = +12.61 V) ALARM
-12V: -17.05 V (min = -12.63 V, max = -11.41 V) ALARM
-5V: -7.40 V (min = -5.26 V, max = -4.77 V) ALARM
Stdby: +1.99 V (min = +4.76 V, max = +5.24 V) ALARM
VBat: +2.03 V
fan1: 4326 RPM (min = 0 RPM, div = 8)
fan2: 2596 RPM (min = 3013 RPM, div = 8) ALARM
fan3: 0 RPM (min = 3013 RPM, div = 8) ALARM
M/B Temp: +52C (low = +15C, high = +40C) sensor = diode
CPU Temp: +127C (low = +15C, high = +45C) sensor = thermistor
Temp3: +61C (low = +15C, high = +45C) sensor = thermistor

[~] hddtemp /dev/hda
/dev/hda: IC35L180AVV207-1: 44C
All my fans are spinning, and the cpu temperature sensor just seems to just be returning 0b11111111.

I could hardly believe these data so I logged a lot of them while inducing a crash by sealing my case and compiling a bunch of stuff. The only obvious trend was a steady increase in M/B (What is this M/B?). I cleaned up the data and put it up here:

Pretty much nothing stays within the proper range. Is this my power supply or the power from the wall or poor ventilation or is lm_sensors just whack or what? Please somone point me in the right direction!

You should check your voltages with a multimeter whenever possible. Although II have never done it, supposedly, your plug in the meter first, then boot up the system. Test it with the system idle, and udner as much load as you can give it.
