It does look like it's a problem with the PSU or (God forbid) the cpu. ("God |
| 19 |
forbid" because new CPU means new motherboard also). |

So, I would say that you have shown that your memory chips are not |

Well at the moment it doesn't even survive the early stages of a short |
| 35 |
compile (the ./configure stage) so hopefully if any progress at all is made |
| 36 |
at diagnosing the problem, it'll be quick. Unfortunately if I were paying |
| 37 |
you to diagnose the problem I'd also have enough money to buy spare PSU's - |
| 38 |
but I'm not! |
