Motherboard won't detect graphics card

First post today, and not really a good one. So, yesterday I completed my first build, if you can call it that. I replaced my PSU and tried to replace my graphics card, changing from a Radeon 5450 to a 6950. I'm pretty sure I connected all the wires where they should have been, including the PCI connectors. When I powered on the PC with the 6950, the PC didn't boot, but the fans started, and the GPU fan at a really high speed. I tinkered around and nothing worked, so I decided to replace it with the old 5450. I took the 6950 out and replaced it with the 5450. But when I tried to connect the DVI/HDMI to the graphics card, there was no display, even though the computer had booted up properly. I remember when I took the 5450 a week prior, that I had to jiggle around with settings to make it work again, but I've tried checking the priority of PCI in the BIOS and resetting the CMOS battery, as well as booting with disabled onboard graphics and nothing works now. When I connected the VGA to the motherboard, I got display, and so now I'm running the onboard NVIDIA Geforce 7025/ nForce 630a.

I'd really like to get the 6950 working, but if that doesn't work out, the 5450 will be fine. Is it usually this hard to get a GPU working? I'm going to go to a tech guy on Saturday, so anything I should know before then?


Current Setup:
PSU: Corsair CX-750M
CPU: AMD Phenom II x4 955 @3.2 GHz
GPU: Radeon HD 5450(not recognized)
Mobo: Asus M4N68T- MV2

Normally its plug n play besides the drivers, but I never had an issue with a motherboard detecting a graphics card other than the one Dell I had where you couldn't use 4 sticks of ram alongside a PCI-E device....

I would try to update your bios if you can, Asus shouldn't be that hard, at least in the bios I think they have a way of doing with a flash drive within bios on that board. And I think it has to be in fat32 format.

Also, make sure your PCI-E is your primary display slot, some boards have an option somewhere in bios for that.

Thanks, I already have the PCI-E x16 as my primary display slot, but I'll try to update the bios and see what happens.

After fiddling around for a couple of hours, after updating the BIOS and resetting the GPU in its slot multiple times, I finally got it to work. It seems that I had to put a lot more force to get it in properly in the slot. Thanks, and I'm going to go see a guy about the 6950.

Thats good, Yeah if you never had a graphics card in the slot before, sometimes it needs a bit of force to press in there. Glad it was something so simple.
