Nvidia 8400 GS Not detected.

Okay, So i bought this Card idk, about 8 months ago.

It's been a great card for my needs, and I've enjoyed it.

But As of today, It isn't detected by the monitor.

When i plug in the VGA connection to the card the screen just goes into sleep mode, like it's not receiving a signal.

But when it's in the regular on board VGA it works fine.

DVI connection does the same thing, monitor goes into sleep mode.

The only thing that i can think of, is when i was putting the card and case lid back on today, The computer fell on it's side. Nothing major, just a slip.

But after that it wouldn't work.

The Fan on the card still comes on, so i know it's not the PCI-E slot.

Does anyone know what's going on here? is my card just maybe dead?

Please Any advice is welcomed.

Thanks.

Yes, But it Didn't fall hard or anything, It was just like if i held it while it was falling

Sorry, had to work ALL day today...

I'd start by removing and re-seating everything inside the PC - All cards, RAM, power connections, cables to drives, etc., with the exception of the CPU. Unless you actually have some thermal grease or can get some, leave the CPU alone, as the heatsink will likely come off the CPU itself when you remove it. Try booting after you're certain everything is in place and secure.

Wait... So you're saying Windows doesn't see it when you're using the on-board VGA?

You won't find the actual slots listed in device manager. PCI-E bus is all that appears.

Have you tried disabling the on-board VGA and setting the Primary VGA Adapter to PCI-Express in the BIOS? If not, try that. If so, unless you have another card to try in the PCI-E x16 slot, there's no way of knowing if the slot was damaged. Similarly, you don't know if the card was damaged unless you can try another PCI-E video card in that system, or try your card in another system and see if it works.

No, Heres the skinny.

When the card is plugged in, The fan runs. So i assume it's getting power.
When i plug a VGA into the card, The monitor receives no signal.
When i plug into the onboard, with the card STILL in the system, Windows does not detect it.

And How would i set the VGA adapter in BIOS, I've scrolled through it and i don't have the option, I believe i have pheonix award BIOS or something like that

It's okay, Just don't worry about it.

I ordered a new PSU, and I bought a 9800 gt, I'm just going to install those.

I just went in BIOS, And there was no option in there to disable On-board VGA...but oh well like i said I've got a new card. Thanks for your help anyway.

Oh i know, If anything i know my cards xD
