Booting Trouble (Power issue?)

Alright, so last night I cleaned and re-applied my heat sink to my cpu, as it had started running too hot to OC. That itself was successful; at stock speeds, i was running at 57 degrees celsius starting up, and now it's back down to 49/50 max.
However, this was all tested before i hooked my case fans, hard drives, and DVDR/W up to the power supply. After turning off and doing so, I would attempt to boot up. At the same point in loading windows, something fails, all power dies, and the speaker starts its siren. The same thing happened after entering bios and checking my temps. (The CPU never rose above 50)
First, I tried plugging different power into the different devices, thinking i was putting both hard drives on the same string of power, but nothing changed. I discovered that if i put power to even one of these devices, the failure would occur, but if i left all devices unplugged, It didn't fail.
I have an A-Bit NF7-S motherboard, Athlon 2500+, two 1 ghz OCZ ram sticks, a 36 gig raptor, 60 gig western digital, and unfortunately, I forgot the exact name of the power supply (stock on the Antech Lanboys, i think 400 watt 'Blue' somethin or other.)
The only change i made to my setup was putting the dvd-rw and the Western Digital hard drive on their own IDE cables, rather than having only one IDE plugged in for both of them. Also, it never occured to me to unplug the floppy, although I doubt that would be the source of the problem?
Any suggestions would be greatly appreciated =).

Hi there... I was going to say welcome but you've been around a while ;)

400W seems like it would be enough juice for that system, but there are so many different qualities of 400W PSUs out there, it might as well be a 250W for argument's sake. So you *could* try swapping out the PSU with a dependable one to see if it persists.

Other than that, and I know this sounds quirky - but how is the power switch assembly on that case? I have seen broken power switches responsible for random shutdowns & reboots. You never know... something to check. good luck & post back, I'll try to assist as much as I can if I'm online.

Thank you for the response, and that's an idea that i've never heard of. I'll check out the assembly when i get home.

What gets me about all this is that I randomly decided to try ocing again in the middle of playing WoW (=P). I shut down, took apart, and reassembled, and that's when the problem occured. Is there anything i could do in that time to ruin the PSU?

Any time you are messing around with OCing, you are presumably adjusting the voltage supplied to your CPU. so i'd say there is a chance you could mess up your PSU.

I generally am not a big fan of OCing, but that's just me. Definitely return your system to stock settings if you haven't done so already to see if the problems persist.

As you said... you have changed a couple of things in your configuration also, such as your IDE config (each to its own channel). If you return to your previously working config and everything works fine again, you might be able to narrow down your problem ;)

I was afraid it might be the IDE thing. If so, I'd love to know how that could be an issue. It sounds quite interesting =).

I should probably have just waited 8 hours to post this, after being able to work on it some more, but I figured getting some input beforehand couldn't hurt.

So if it's an ide problem... do you think it's the port or the cable?

Thanks!

9 times out of 10 it would be the cable.

it's pretty wide-ranging what your problem could be at this point though :)

check your connections first, then see about trying another reliable power supply. that will scratch two things off of the list, at least.

Alright, I'll post back later with the results. Thanks, I was unsure whether a bad IDE plugged into a secondary hard drive or dvd rom could cause a shutdown.

Thanks again.
