machine posts, starts to boot then shuts down.

Plugged a second (new) sata drive into my machine. Powered up to format; ya da, ya da.. Machine powered down shortly after power was turned on. Removed sata and tried booting up again. Same results. Reset CMOS to default settings and powered on again same results. Machine does get to the point where it staarts loading windows, have even gotten into Windows once befroe it powered down.

Thought this might be a power supply issue but moved the supply to another machine and it works without issue.

Any thoughts?

Sounds more like overheating the processor. Check your fan/heatsink on the CPU, maybe it was moved by accident when you added the drive.

How about booting into Safe Mode? I agree with JohnThePhoneGuy this is the classic symptom of an overheating CPU. Especially if it's a socket 775 with the wacky Intel black plastic clips that love to pop off.

Check Event Viewer to make sure it's not a faulting driver, although that would give you a BSOD. This is another case where a Live Linux CD like Knoppix or Puppy would be handy, to see if it's Windows or the hardware. My money's on the hardware.

Yeah...sounds pretty random...software (driver) shutdowns tend to be at a particular point in the boot process, I'm going with hardware on this one.
Did you knock the cooler installing the extra SATA drive?
I still wouldn't rule out the power supply just because you tested it on another machine. That machine may be less demanding and so less stressful on the PSU.
Can you post more info on your setup.

Pretty sure I didn't touch the fan/heat sink. Nowhere near where I postioned the hdd or cables.

Regardless looks like the shut down occurs at 100 degrees F. Didn't see where I can adjust the setting, seems like temp is low to have this issue. I downloaded the mobo bios pdf to see where I reset the autoshut down temp. Can't seem to locate. Can't get into windows so can't change settings there.

I'm with Martin, different machines present different loads to the power supply. I would try another power supply.

Regardless looks like the shut down occurs at 100 degrees F.

Are you sure? 100F is like 38C, well within safe operating temps. If you reset the BIOS to defaults it should be fine, no BIOS has that low of a thermal shutdown threshold by default.

I repeat, run a live Linux CD, AV scan from CD, or even memtest86 to check current hardware, anything that runs outside of Windows to see if the machine keeps running after warmup.

You first need to separate the problem at its root: hardware or software?

strange idea, memory stick trouble? try them elsewhere or remove 1 stick if you have one, replace them and see.

OK, this is what I found...

I normally don't have the speakers plugged into the machine and I have the video card plugged into a KVM. I tell you this because if I had the sound working and seen the early boot notices (which I missed because of KVM switching from machine to machine) I would have heard or seen a mention of clocking. The warning was something about the cpu clocking wrong. Not sure why but I went in and made sure the bios setting were right (which is odd because I had set it to the defaults). Rebooted the machine and now it's up and running.

Good news is in addition to fixing the problem I put an extra fan in the case so it's now running a lttle cooler that it was originally, after 15 minutes with low usage 44c/111f.

Appreciate all of the help and advice.

For next time...STEP ONE in troubleshooting is isolate the machine from ALL peripherals. Well, maybe not, STEP ONE is to reboot, but you get my drift.

Glad you got it working, but there was a lot of time spent on something that should have been discovered WAY earlier! Live and learn.
