I u want zero recovery possibility then use Darik's Boot And Nuke

If u don't want to wipe the whole drive just specific files then use file shredder software.

How did you determine the motherboard is bad? What are the symptoms? Although boards do go bad, there are other components that are much more likely to be the problem, such as the power supply. And if the board IS bad, you will obviously have to remove the hard drive to be able to wipe it.

I tried to directly plug it to a power supply and the green light is on in the back. Doesn't that indicate mother board not power supply? As you can tell I am a novice at this!

"I tried to directly plug it to a power supply"

Tried to plug what to the power supply? The power supply is a box inside the computer. It converts the AC voltage to DC then splits it into several different DC voltage rails. The main 3 rails are +3.3v, +5v, & +12v. If any one of the 3 rails is bad, the computer won't boot, but there may still be enough power to light the LEDs or spin the cooling fans. When you attempt to boot the system, do you hear any beeps?

Here's what a power supply looks like: http://www.pcstats.com/articleimage...

No sounds or beeps when I try to boot the system only loud fan motor. Then can't turn off without unplugging it - not able to by power button.

Sounds like it may be a mixed die off. Most systems i have seen (old ones at least) have the pwr button hooked to the PSU directly. The newer (2007+) computers, however, I have yet to open one up. I have no idea how those pwr buttons work BUT if I assume they may hook through the MB. The fan means you still have 12v most likley. Try plugging in the power then plugging in a USB device (thumb drive, MP3 player, etc.) into the computer. If it has a little light and it lights up, means you have 5v too. Then you probably have a bad MB, and not PSU. There is a limited amount of diagnostic work we can do from here though. At this point, you might want to find someone in your area that knows what he's doing inside a comp case (preferably without pay) to get your HDD out and copy/wipe it, put it back in, then you can take it back to whereever you got it from and complain.

P.S I forgive you for being a noob, not everyone can open a comuter case and find the problem in 8 minutes ;-)
EDIT: Yeah, what did you plug directly into the power supply? i'm having a ard time fol.owing you.

AT systems had a power supply with a hard-wired on/off switch. They haven't been used in at least 15 years.

ATX systems started in the mid 90's. They have the case's power button connected directly to the motherboard. The ATX power supply (unless it is switched off or unplugged) maintains a constant voltage (Standby power) to the motherboard. When the power button is pressed, it sends a signal thru the board to the PSU & it 'wakes up' & powers on.
