pulling everything out the system does not guarantee that it will work if the problem is the PSU. You are probably thinking that a bad PSU just doesn't put out enough power, and that isn't the case. You could be having voltage swings causing the entire mobo or maybe just a few components to shut off randomly causing all sorts of weird problems.

There are 2 ways to test the PSU

1) use a PSU tester (which I'm sure you don't have access to)

2) use a different PSU and if the system works, then you know the old one was broken

EDIT:
as for antek vs corsair, I don't think there is much of a difference in quality. If the price is the same pick whichever you feel better about. The guy is probably the unlucky guy who got a bad PSU and swore off antek forever for no legitimate reason. It's like saying Honda makes worse cars than Hyandia just because you got the one bad one so you switched to Toyota.

All of this. As someone that had a Antec PSU go bad many years ago(and create many similar problems to the OP) I was inclined to guess PSU myself. But I'm not trying to say that it's Antec that is the reason it failed. It's not uncommon for even good power supplies to kick the bucket after years of use, and 4 years of near-constant use just may have been too much. Corsair generally has great products, and it's what I put in my build earlier this year, but I'd go Antec again for the right price.

So the DB glitch actually spread to your whole computer?

Arrr I got an antec too (750 bronze blue or something).

Little story... when I changed my GFX on my last comp, i miss pluged the cooling unit... I had lines and such when it started over-heating then crashes (didn't help that we had a heat wave so I didn't find the problem before a week....) is your gfx temp kept in check? Otherwise, you could always upgrade, your card can't be called new anyways.

For the PSU... never had problems with my antec (my comp only ever crash on an nvidia related error.. (probably cause the cards barely fit in the case or overheats :p))... well besides my laptop that doesn't work... need to fix that (though that could be a fried mobo too).

wait...

I thought you were late on the mafia game cause you scored on saturday.... this is very scumy indeed....

Ok, so, I pulled every slot of RAM, 3 of the HDDs, and DVDROM, graphx card..

It finished POST. 

But I still get a beep at 26 on the POST which is:

"1. If Early_Init_Onboard_Generator is not defined Onboard clock generator initialization. Disable respective clock resource to empty PCI & DIMM slots. 
2. Init onboard PWM 
3. Init onboard H/W monitor devices"

And the beep code is:

"1 long, 2 short Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information"

It finally finishes POST with a barebones setup, but the beep is telling me that I have no monitor use.

Antec can make some excellent PSUs....PC Power And Cooling is who i'd worry about now...And Rosewill

You took out the graphics card right? Is there onboard video?

No onboard video, that shit is trash. I would never buy a mobo with onboard video.

Anyway, there is an update to this:

I took out everything except for the OS HDD, one stick of RAM, the cpu and sink.

My board has onboard debug, and it passed post;POST code 'FF'.

This lead me to believe that the PSU was the problem.

So, I bought a new PSU from BestBuy because apparently, you can return any PC components to BestBuy for free (awesome).

Hooked it all up...GPU still didn't work. I then took the time to open up the GPU casing/shell, and definitely smelled a slight charring. Tried to boot it up again with everything in place, and it passed post again.

But, that was with the new PSU. I'm gunna try putting in the old PSU again and see if it posts, which would definitely be weird, but I've seen weird stuff like this happen with PC components plenty of times.

Additionally, when I was talking about my mouse getting 'interrupted'; turns out, my mouse died exactly at the same time as the GPU. What a crazy coincidence. The mouse failing was making me think that USB was failing, and pointing to a mobo problem. Nope, the mouse just actually died.

Today I bought a deathadder mouse and a ZATOC 1GB GTS 250 Eco Edition. Total cost of 130$. Not bad. The products are shown below for any interest you may have.

I'm actually hoping they can cancel my GPU order, because I would rather get a 5770, specifically, the sapphire 5770. For like 150$.
