I've stripped it down to the bare essentials as is often prescribed.
Chaintech NF3-250
Athlon 64 3000
Heatsink and fan
Power supply
front panel switcher

I know it's getting some power cause I can hear the high-pitch tone from the electricity. And I think I have the front panel connected correctly because the LED has a faint glow to it. Also when I press the power button the board makes a click sound then a long quiet beep when I hold the button. But alas it won't power up. I think I managed to clear the CMOS but there's no way to tell for sure. so, any ideas?
 
I would remove the board, and place it on a non conductive surface, such as the box it came in or a phonebook. Use only 1 memory stick, cpu/heatsink, and video for posting. You can connect the power supply switch from the case or use a screwdriver to short the power switch leads. With just the atx plug and 12v 4 pin connector, it should post.
 
Using your method with the screw driver it started making noises like a fuzzy tape recording but alas no startup

Suppose my 230W PSU might be to blame?

Yeah. It's a shame that people are willing to invest hundreds in a new rig, but not the power supply. I recommend the sparkle 300 watt with 12cm side fan. It fits standard atx cases, and is only $28 at newegg. It's heavy duty, and very quiet.
 
Your board is grounded somewhere. Did you remove it from the case? Did you mount the board directly in the case or you have used the mounting post? Did you use the same number of mounting post as you have holes in your mobo? Did you make sure that every posts has its screw,or every holes has its post? an unused post might be grounding somewhere underneath the board.

-Always put the blame on you first, then on the hardware !!!
 
Did you remove it from the case?
Yes

Did you mount the board directly in the case or you have used the mounting post?
Both. posts on the edges and directly in the middle.

Did you use the same number of mounting post as you have holes in your mobo?
There are some holes on the very corners but they don't look like they are made fore screws and there aren't any post holes under them on the case.

Did you make sure that every posts has its screw,or every holes has its post?
Well this motherbard is smaller than my old one so there are a couple extra posts
 
In reply to:

you have to use posts on all mounting place on the motherboard. The back of your motherboard is probably touching the case and it is grounded. Just hope that it is not fried!

It is so not touching the case, it is laying firm and level
