Re: Computer wont power up sometimes, runs fine

It may even be my cpu fan sensor.

Very unlikely given that it should be at the lowest temp at boot time.

I said nothing of the temerature sensor.

I never said you did.

My motherboard will detect the FAN on the cpu.

You dont get a shutdown like you are seeing if it cant see the FAN.

That is why I mentioned the setting to shut down if the cpu fan
fails. If that sensor is screwed, then it will shut off as a fail-safe.

Doesnt explain why it only sees that at boot time.

I don't know what the default setting is. So untill I can
get into my bios again, I cant rule out this possibility.

Sure, but its still a lot less likely than a faulty power supply.

I know my processor is fine tempurature wise. It won't go
over 40C unless it's under heavy load. Usualy it camps
around 32-38C (which is nice considering it's stock cooling).

Yes I meant that is unlikely to be getting the cpu temp wrong due to
a fault and shutting down the motherboard that quickly on power on.

I'm still investigating the possibility of the powersupply being
the issue. I may pull it out and try my luck on my old computer
(which is now my roommates). It's just a huge pain to get it
out of the case (and a bigger pain to get it back in).

I would think that his system is every bit as power hungry as mine
(probobly more so). But it uses only a 20pin main connector. I
don't know how much difference those additional 4 pins make.

They're extra 5V lines.

I may have too much faith in OCZ's high standard.

Any electronic device can fail.

But I do know that both ABIT and MSI where known to
use inferior capacitors on their motherboards in the past,
resulting in preasure buildup and eventual leakage.

Yes, but you can check for that visually and that doesnt normally
produce the particular set of symptoms you are seeing.

Though my former ABIT board is running just fine as I type.
And I've carefully inspected every capacitor on my current
MSI board and found nothing more than a barely perceptible
layer of dust atop the ones just next to the processor.

Then its unlikely to be a cap failure.

I just dread going through the whole RMA process when
I could give it a day or two and be back up and running.
Untill I have some concrete evidince,

The only viable evidence will come from a power supply swap.

I'm not willing to send either mobo or powersuppy in for repair.

I don't know if you've noticed, but despite my obvious access to computers
and internet, I'm completely disfunctional without my main rig. My art, music,
and reading matterial-- both informative and casual fiction--not to mention
games are all in my own little binary world.

Yeah, I wouldnt dream of relying on just one system ever again.

It's been my drug since I was ten years old and I can't quit cold turkey.
Not even for a week. No amount of chocolate can compensate. Believe
me i've tried. It's expensive, and unhealthy. And eventualy all the excess
sugar acts as a catalyst for depression (and my coping mechanism wont
start up right now). It's a vicious cycle that can only end when my
powersupply and/or motherboard decides to start working again.

ARG. But thank you for the help. I'll try testing my powersupply
on the other system and post back with the results.

I'd RMA the power supply if it was mine.
