Elusive problems with MB/HD/PS???

[tech405]

A little bit of history....

Flashed my bios Friday night about 8:00pm. Worked on the computer until around 2:00
Left it on all night, and around 11:00 Saturday morning, started a DVD conversion, the comp rebooted and errored out on boot up with a Read error on the HD.
spent all Saturday downgrading the bios, testing doing different things with the HD (which is still seen in the BIOS), and finally installed Win2k on a little 20GB WD drive Saturday around 7:00
Surfed that evening, and then Sunday morning, bam! Same thing with the drive...read error.
So, eventually I bought a new MB, thinking the bios was corrupt and my old MB was toast (Epox 4g4a+)
Hook everything up to the new MB, and *click* *click* no power. So I yank everything out, pull the PS out and try to plug it into the new MB, AND the old MB, and nothing.
I bring the PS into work to test, and it's fine.

The new system board is a FIC something or other. Just something Compusa had (cut me some slack, it was sunday night at 5:30, and I get impatient.. )

Does anyone have suggestions as to what I might try?

You sure you have the leads to the switches on the case connected to the proper pins? Be sure you have the reset and pwr on the correct pins.

How is the HD listed in the BIOS? Is it on Auto or put in manually. Try using the BIOS's auto-detect if it has one.

The HD is auto detected in the bios. As for the other question....is it based on the MB whether the pins need to be connected or not? What I mean by this, is I tried with and without connecting the pins. I tried without, because I thought I could have them backwards or something.

So, when I brought in my PS and plugged it into one of the spare IBM's here, I only plugged in the ATX power connector, but not the pins. When I gave it power, the fan (in the PS) started right up. This doesn't happen when I plug it into the two system boards at home.

Did any of that make sense?
