We had an intermittent power failure last night.

I woke up this morning and wandered into the kitchen, and saw that, in place of the time, the LED on the microwave was displaying a “PF.” Most of the clocks have battery backups, but the one in our antique (sixties era) electric stove was about an hour behind.

Computers had to be restarted, natch.

After doing so, I was using my desktop (my primary work machine) for about a half an hour (the one in which I’d recently replaced the motherboard), when it decided to reboot itself, seemingly spontaneously.

Then, after the reboot, right after login, and the desktop coming up, it did so again.

After repeating this two or three times, it bluescreened. This was similar to the symptoms before I replaced the mobo the last time. Except that this time, after finishing writing whatever cryptic diagnostics it was sending to that future, in which the technology might exist to revive it, it didn’t reboot–it just shut down.

And wouldn’t restart. Poking the power button was availless.

So, now I’ve got to figure out what’s wrong with the thing now. I may have a power supply problem, but I may also just need to upgrade to a better board.

Anyway, I’ll be working on the laptop for the nonce.

[Late afternoon update]

Dang.

I was hoping that it was the power supply, but I just tried another one, with the same result. The power switch is fine, based on a test with an ohm-meter, and shorting the terminals on the motherboard doesn’t give any action, either.

I still need to verify that the supply I swapped is good, but it looks like there’s a problem with the mobo. I just bought it about a month ago, and it’s probably on warranty, but I only paid thirty-some bucks for it, so it may be best to simply upgrade and get a more modern one.

Oh, as for the suggestion in comments to unplug everything from the board except the video card? That’s already my configuration. Everything else (sound, ethernet, etc.) is built into the board.
