"No Signal" after upgrade

[br8nd4n]

Hi all,

 

New to the forum and wondering if anyone could be able to kindly assist me.

 

I have an Athlon AMD AM2 quad core desktop with an onboard Nvidia GF8200E graphics card and a 450w PSU. I have purchased a second hand ATI radeon 3870 HD graphics card to upgrade to which I have slotted in to the the PCI-e slot. The card appears to power up and the fan spins however I have "no signal" from the monitor. The card came with no disk however I have downloaded the drivers. I have checked obvious stuff like making sure the DVI cable is plugged in properly etc.

 

Can anyone please explain to me where I am going so terribly wrong!

 

Kind regards and thanks!

Hi br8nd4n.Welcome to Extreme Tech Support - Free PC Help.

Any clues in device manager?

Did you uninstall the old Drivers,or try and install over the old Drivers?

The light (Blue) on the Monitor.Does it come on at all?

Hi DSTM, thanks for the prompt supply.

 

I did uninstall the old drivers via the Device Manager. I have tried using my monitor and LCD TV but both display no signal. The card is definately seated properly and BIOS is set to use the PCIe before the IGUP. I'm not particularly technical so if there is any other straight forward advice you can give I'd be very happy to receive it!

I would be testing the Card, in another working Computer.

Chances are, the second hand Card, could be faulty.

Are you plugging the Monitor into the correct slot?

Yes. I've tried both DVI ports, but no joy unfortunately.

If you were using the onboard then you need to go into the BIOS (it tells you how to do this at the POST screen if you can see it) and disable the onboard, where you disable the onboard there should be a section that says initialise display first - make sure this is on PCI-E

 

To do the above unplug the add in GPU card, then plug the monitor cable into the socket near the USB and keyboard ports on the back of the MOBO you should then get a signal :)

Just so I'm not one of those people who sorts their problems but doesn't tell anyone else on the forum who might also have the same query:

 

The card must have been faulty. I purchased another ATI HD3870 and it works fine now. Good card in fact! I'm happy now.

Thanks for the update, and glad you found it was the card.

Second hand computer parts should always be tested where possible, preferably before buying, though I recognise that may not be possible when dealing on line.
