I believe P5-133XL's terse post, is in reference to motherboard error beep codes.
Though, today's motherboards (haven't looked up yours, so don't know for certain) usually come with integrated speakers, for just such a thing.
I assume that you can't even see the bios? If you had spare parts laying around, I'd suggest slapping in an old PCI (not PCIe) video card, at least to get into
the bios. A long shot could be that video is not set to PCIe first, so it's looking, and can't find the source because it's on the wrong bus (just a thought - don't know if it will work).
If the board's got more than one 16x slot, I'm sure you've already tried to swap slots, to see if it will work?
Also, I'm sure you've already tried to remove and re-seat the card?
Are you're system fans spinning up, so you at least know it's got power?
Does the motherboard have the latest bios?
Because the CPU and Motherboard are both new variables, I'd suspect those first (ie. bad CPU or MB), but again, without spare parts, it makes trouble shooting difficult.
Difficult to help diagnose, without more information.
