PC update cubed

General
The verdict is in - it was the power supply! Don't you just love intermittent faults? That's why my PC managed to boot the one time, and failed the rest of the time. At least it doesn't seem to have harmed the new motherboard. Anyway, I'll be getting a good new power supply, and the shop will make sure that everything is working properly before I get the PC back in a couple of days.

Intermittent faults; the story of my life at work. The Navy instructors say that the training systems don't work properly during the day and when I come in at night, see the trouble tickets and go to fix the systems, they're working just fine. Equipment malfunction says they, operator error says I. That, or I'll be chasing a system fault for a week because the fault goes away after the system has been on for 15 minutes and the electronics have warmed up, I kid you not.
On a side note, loving all your MLP stories.
Hmmmm, maybe the PCU was meant for the US or some other county's voltage and not an Ozzy one :P
International voltage can be...umm strange. Well hopefully this one works right this time!
PSUs go bad for all kinds of reasons, though. Usually what happens is that the electrolytic capacitors start drying out due to excessive heat, which changes their values and destabilizes the regulator and filter circuits, which in turn causes the power supply to be unable to keep the DC voltages within their specified ranges. Running a power supply right at its rated capacity can shorten its lifespan, as well, which is why I always advise going with something at least 50% larger than what you actually "need." (I.E. if your system needs a 400W power supply, put in a 600W unit; if you've got a hardcore gaming rig that's going to pull 600W or more to keep those dual video cards rendering a zillion polygons a second, get a 1KW unit.) It costs you a few more $$ up front, to be sure, but it'll save you money in the long run because the supply will last longer and be more reliable.
Ahhhhh, I didn't know that. That is good to hear all PSU can work with all kind of ranges and voltages.
Yeah yeah, they can go out for all kind of reasons sadly.
And thankes for the tip, I thought having more power then you need was a good idea but a more concrete reason why is even better.
