I wouldn't trust these numbers. You probably need a different/correct driver |
| 37 |
in your kernel to measure your CPU and MoBo chipset readings and/or a later |
| 38 |
BIOS firmware. |

Whenever I had such problems they were down to bad memory (some PCs are rather |
| 41 |
particular in only accepting matching memory modules) and also down to a sick |
| 42 |
power supply. |

Memetest86+ should tell you after some hours if something is amiss. |

| 46 |
The power supply problem will require opening it up and checking for domed |
| 47 |
capacitors. A few cents later and with a soldering iron in hand you should be |
| 48 |
able to fix any cheap capacitor induced failure. |

Of course if the machine is hundreds of miles away, attending to it is more of |
| 51 |
a problem. |
