Alright here's the summary of whats going on:

my old mobo burnt out, so i replaced it with this: (link later, newegg wont load atm)
once i installed it, i realized it had no agp slot for my nvidia 6600, only pci-express, so i temporarily put a pci 5500 in.
then i ordered this: (link later, its a gtx 260)
received the card and installed it, only to find that as i thought, the old psu was not strong enough for it.
ordered this psu: 750w thermaltake
got that in today, and installed it. turned on the pc, and everything is receiving power, all fans, lights, hard drives, dvd drive, etc receiving power. however, i get no display, the monitor immediatly goes to sleep when i power on the pc. here's a list of all the things i've tried, all of which have had the same effect, no display on screen, no beeps, no post, no bios:
-trying a vga monitor
-trying the onboard video
-removing the 260, trying onboard video
-installing old pci 5500
-installing old pci 5500 in the same pci slot it used to be in, removing every other pci device
-tried the other side of the 4+4 connector to my motherboard (only has 4 pin conection on the board) repeated all above steps.
-tried switching ram sticks around

I've triple checked every connection and they are all secure. at this point no matter what i do, i cannot get anything onto the screen. I think thats all the relevant information i can think of, please help if you can.

edit: was trying some stuff with the cmos, and some smoke got out from the vicinity of the pci card. i cant visibly see anywhere on the card or the board nearby where it came from though. *sigh* it's just one thing after another, im gonna leave it alone for a little while hopefully you guys have some good suggestions for me.

some smoke got out from the vicinity of the pci card.

Obviously not a good sign. Take everything apart and look for scorch marks, see if anything smells burnt.

once i installed it, i realized it had no agp slot

Do you mean to say that you actually forced it in a slot and turned it on??

update on the smoke, its a very small strip leading to the pci slot the 5500 was in, thats burnt up now. hopefully that only affects that pci slot and nothing more.

once i installed it, i realized it had no agp slot

no... i took out the first motherboard, which is used an agp 6600 on, put the new motherboard in, and saw that there's no agp slot, and set aside the 6600, and put in the regular pci 5500. then ordered the new 260.

It doesn't take a whole lot to destroy the solder trace. Don't forget that's a multi-layer board.
Do not spend any money trying to fix it
How long ago did you purchase it? Google's pretty good with RMA's

links update-
http://www.newegg.com/Product/Product.aspx...N82E16814127361 - video card
http://www.newegg.com/Product/Product.aspx...N82E16813138079 - mobo

update comment from another forum-

Call thermaltake, or RMA to newegg, I am thinking that the switches in the PSU are giving under and over voltage, leaking power all over your mobo while never doing anything useful, but if thats the case, it poses the possibility that the PSU has already fried your mobo.

FWIW: I suspect that a phone call works better than an email for requesting an RMA, based on my 1 experience with doing such. Vendors may have prerequisites (questions, diagnostics) which they will go through before granting any RMA and a phone call to a person will probably faciltitate such.
