Solved Graphics card not detected-again

Specs: Windows 7, i3 2100/4 gigs ram
My computer is a Cyberpower 1313 with a Biostar H61MH motherboard. i3-2100 cpu, onboard Intel graphics. I bought this with the intent of installing an 8800GT I had laying around. I upgraded the PSU before I installed the card (HFX PRO650W) so I know I have ample power.

Of course, I wouldn't be here posting this if the card worked. The fan started spinning but the recently downloaded NVidia graphics said "no compatible hardware detected" (paraphrasing). I took the card to a nearby small computer repair shop and asked them to test the card. I now have my doubts that they really tested it before telling me the 8800GT didn't work.

OK, my new PNY GTS450 just arrived and I stuck it in with the same results. Believe me I've searched and searched this type of issue. I'm not a "dive into the Bios" kind of computer user but I did. I went into "Advanced>Chipset>Northbridge>Initiate Graphics Adapter" and set it to "PEG/PCI" (per advice given on this forum I believe, maybe some other forum). And that doesn't work either. Intel graphics work fine. BTW, I can even play L4D2 with Intel graphics. And, yes, I did hook up the monitor cable to the card. Anyway...

I think I saw in there that the PCI-E slot is "enabled" so I'm at a complete loss as how to proceed.
NVidia drivers don't detect my PNY, Device Manager doesn't detect my PNY, it's like the PCI-E slot doesn't work, but what do I know? All the advice that the computer will "auto detect the new graphics card and switch over" has proven wrong in my case. What should I try now?

✔ Best Answer
The monitor cable needs to be connected to the new card plus the card needs to have the additional PCIe power plugs connected to it. The PCIe slot can not supply the required power, so connecting the PCIe power plugs (either 6-pin or 8-pin) is absolutely necessary.

The monitor cable is hooked up to the card and the six pin power supply cord is hooked up as well. That is, the monitor cable is hooked up to the card as I try to reboot, fingers crossed, hoping my monitor will light up. "No signal detected" is all I get. So I switch it over to the Intel graphics and all is "good".

I read another discussion on Tom's where the OP had to do a complete wipe and re-install to get his Biostar motherboard to finally detect his discrete card. He had tried everything I've tried.

Does the Biostar H61MH have some physical jumper I need to move?

And, if this isn't the right forum to ask these question, please let me know, I'll put it in maybe the motherboard forum or something. Thanks.

I've done this before on a Dell Inspiron 530 (years ago). I popped open the case, stuck a 7600GT in it and it was recognized instantly. I still use that computer. I thought it'd be that easy this time.

I mean, it could be something as simple as some other change in the Bios, which a guy like me would not be looking for.

It's not a jumper, it's not a BIOS setting, & it definitely has nothing to do with Windows. The card should work as soon as you boot up. The fact that it doesn't means that the card is either installed incorrectly or it's defective.
