Okay, so my previous system was a Asus P4T-E with a intel 1.8 on RIMM with a radeon 8400 with a 350 Antec running 2 HDD's and 2 IDE Drives.

After about 3 years I guess the OCing burnt out the MB so I got a new iWill MB. I used my friends ti5200 and everything seemed fine and dandy until at some point the AGP slot stopped functioning for some reason. I thought this because my gfx card wouldn't power up. So the first thing I did was swap my radeon back in there and the fan didn't power up either (but for some reason this crappy gfx card from my GF's dell seemed to power up but got no readout). So i ran to my friends place and tried out both cards and they worked fine. So then I went out to get a PCI gfx card and everything worked fine.

I decided to just upgrade my system some more so I can return that crappy PCI gfx card and bought a ECS KT600-A MB witha AMD 2800 XP and 1 gig of corsair PC3200. The problem this time was that when everything powered up, there would be no read on the monitor. So I went ahead and got a different stick of RAM (since there is a compatibility problem with many of the 3200 series RAM) I picked up a PC2700 and tried it again and it didn't read on the monitor. So I switch out my GFX card to another one and still no read. Then when shutting it back on and off the damn thing wouldn't turn on anymore, yet when swapping back the other P4 system it works. I'm thinking it might just be a problem with the MB's. any advice?

Sounds like a power-related problem. Check your power supply, and also make sure nothing is burnt out on the motherboards' power supply circuitry.

it's kind of like those math problems, you can only fit two people in a boat but Frank, Jim and Sam need to cross the river...also Sam and Jim can't ride the boat together and Frank doesn't like to ride alone.

My suggestion is probably redundant considering it seems like you've tried all possible configurations, but when all other theories have been disproven the least likly theory must be right (or a theory you haven't come up with yet). Sounds like you kicked your motherboard's ass, wether by ESD, powersurge or just plain bad board.

It doesn't need to be said, but you should use the process of elimination to figure what parts are bad. I've seen this problem a lot though and I can safely say that half the products we get back are hit with ESD of some sort.

Nothing makes my day, but also breaks my heart more than telling a 14 year old kid that his board is fried because he placed it on the carpet.

"but i just took it out of the package and placed it in the case whilist using a proper grounding wristband."

"then next time you should avoid wearing furry gloves while doing the install"

You didn't play around with the heatsink or CPU did you???
