graphics card not detected

jakejacob0 · 25 May 2012 at 16:53

Got my new 7950 today.

So far i have:

Uninstalled old nvidia drivers , reset, then used driver sweeper.

I then turned off the pc.

Swapped over the graphics cards.

And now it is not being detected and the VGA light on the motherboard is red.

I have connected two 6 pin pci e cables

HELPP!!!

Make sure the power cables are firmly connected (both ends if it's a modular PSU).

Try re-seating the card in the PCI-E slot.

i just googled it and was i suppose to unistal the previous card in device manager before removing?

The problem you describe would appear to be hardware related so that wouldn't be relevant.

What PSU do you have?

jakejacob0 · 25 May 2012 at 17:05

tx 850 , corsair unit, its brand new

try different PCIe slots?

Still not working!

Tried in a different port and doesn't work either.

But if i remove the GPU and use the onboard graphics display works.

Yes, you should un-install the old card from device manager.

jakejacob0 · 25 May 2012 at 18:08

Done that but still does not work

dave_beast · 25 May 2012 at 18:12

Does the fan spin up on the card when powering up your system?

Also, is there a BIOS setting to choose between on board graphics and PCIE graphics?

Mysterae_ · 25 May 2012 at 18:18

Also, what port do you have your monitor plugged in to? The new graphics card or on board?

jakejacob0 · 25 May 2012 at 18:35

I have change the option in the bios to choose PCI Express first.

And have the monitor plugged into my new graphics card

Mysterae_ · 25 May 2012 at 18:43

You didn't mention if the fans on the new card spin up when you switch on?

The only thing I can suggest is to restart with your monitor connected to the onboard vid, install your new drivers, switch off, connect monitor to new card and switch on.

If you aren't getting any video at all, not even bios screen with the new card I'd suspect it's DOA.

jakejacob0 · 25 May 2012 at 18:51

Oh forgot to check the fans. What do i do if the fans spin or don't spin?

jakejacob0 · 25 May 2012 at 19:38

UPDATE: The graphics card spins up and the fans stay running but no matter what display port i try nothing shows and the VGA LED shows up for the whole time on the mother board.

Tried having the monitor plugged into motherboard while card was in but still no display.

Anyone else got any ideas?

Clutching at straws here, another pcie slot?

Also, when the fans spin up on restart, do they settle down or are they full tilt all the time? If they don't go down to low speed eventually I'd say the card is faulty.

jakejacob0 · 25 May 2012 at 21:22

They just run at normal speed i think, as is i cannot hear them but can see them moving. Well my nvidia 560 works in the pci slot and already tried another slot =/

Think OCUK will be getting a phone call tomorrow and see if they can sort out a swap but means being without a gpu for however many days which sucks!
