My 6800 GT gives no video signal :(

Hello, I hope someone can help me out
This is my story
PNY nVidia 6800 GT
(No OC, drivers updated)
One day I tried a cheap 450 W PSU and made a stress test in Counter Strike Source but suddenly puf!! the PSU went to another life. Inmediately I changed it back to my old 350W and everything was OK. Hours later my monitor went black, I rebooted and hours later the same story.
I moved the vcard to 3 different PCs to see if it was a bad configuration in my sistem or a HardWare issue that causes this, but I had the same problem on those different PCs.
I dont have video signal on the VGA neither on DVI.
The PC boots, I can hear the start up windows sound. The fan is on, but I NEVER get video signal.
Now I have to use my old video card...
Is there anything to do before I ask for my RMA?

if it doesn't work in 3 systems, then its more than likely the card is dead.

RMA it

Yea its shot. Also

to the forums. Sorry to hear about your loss

Maybe try the DVI port on the card. When ever I use the blue colored on on my Ti4200 I get a black screen. I use the DVI one and it works fine.

my pny 6200 did the same thing but intermitent if thats a word it would boot then none no booten at all its going back tomorrow

thanks everyone! I already tried the DVI... same thing...
well, i'll start the RMA process, i hope it doesnt take too long
i miss those great graphics
oh god... thanks i didnt made any OC and i have my guarantee
