PC not detecting video card?

[osokk]

What you need to do is enter BIOS, by hitting repeatedly DEL, until you're in the menu. Then, look around for the primary display adapter. change to AGP and then, look for video memory sharing size. Set it to None. It should make the AGP card detected. Are you seeing something from the card?

i have it set to AGP i will try to change the memory sharing size to none and i will get back to you.

Ok this is what i can see in my BIOS:

Share memory size:
32
64
128
disable

graphic win size:
32
64
128

Now I went ahead and installed my 7800gs and then went to BIOS and set my share memory size to disable. I then had it save the setting and it rebooted, but there was a problem when it rebooted i had nothing but a black screen with a bunch of symbols with color and it wouldnt fully boot to the desktop. I then took the 7800gs out and put in the ATI and went to BIOS and put setting back to default and then rebooted and it went to desktop fine. One other thing is when i had the 7800gs in and had my monitor hooked up to the back of the 7800gs the monitor wouldnt even come on it stayed in sleep mode it looked like but when i hooked it to the back of the mobo it was fine. Between the share memory size and the graphic win size which one is the right one that i need to be messing with?

Your 7800GS is bad. Return it. That's the only way you can do it.

yeah I was about to say the same thing, sounds like the 7800GS isn't working at all. Thouhg I'd try it on a different computer before returning it, just to make sure.
And you have plugged the power cable into it?

Pluggin the Power cable is vital for a card to work, but if you've done that, you could try it on another PC, liuke mammikoura said, but I'm more srure it's DOA.

DAMN IT! i was afraid of that. but yeah i had it plugged into power this whole time. i got a warranty on it so. now just need to find a pc to test it on.
