well i couldnt get ahold of pny tech support so i called every other mnf. i could think of turns out they all just said what u just said... flashed the bios and up it goes. yay right?
Jerreece didn't say to flash the BIOS. The fact now that it's not progressing can't be great news, but it's not overall bad.
First, do all of this with your old GPU.
Since it did POST, enter your BIOS and reset it to default (factory) values.
If that doesn't work try to reset the CMOS manually via a jump switch or by using a screwdriver on the CL_CMOS switch on the motherboard. Not sure what yours is called (next time, please provide the motherboard and your specs), but I have an AMD board. When you reenter the BIOS after resetting the CMOS, makes sure to reload optimized or factory defaults.
Once everything works out, then try to swap out your old GPU for the new GX2, and if it displays nothing, then I'd agree with Jerreece that you may have gotten a dud, and RMA-it.
Make sure you have your PCI-E enabled, too, when you're in the BIOS.
