Gtx 980 problems

[Richie10979]

Hi guys this is my first ever post as I'm completely stomped, basically my graphic card stopped being detected by windows (10) I reckon it's must be a intermittent fault.. 3 days in a row I tried it, in both pci sockets, two power supplys both 650w, disconnecting everything apart from one hard drive and motherboard and graphics card, it's defo not software related because I reinstalled (just to test ) Windows 7/8.1 and 10, as soon a I put my old hd7970 in it worked straight away no problems on all os's, 5 different hdmi leads.. Not to mention my motherboard which I updated the BIOS and it wouldn't even recognise the graphics card, nor would windows device manager but It did straight away with my old hd7970
I've just Rma'd It with scan, they tested it within a day or so but found no problems.. So are now sending it back to me.(at a cost of £30!!). There test bench is very similar to my set up, it powers up and the fans spin, nvidia drivers won't even detect it!! This is my set up
i7 4790k
Motherboard z97p latest bios
650w psu gigabyte recommens 600w min
Windows7-8-10
120gb solid state (os)
8gb ram
Anyone else had this problem?? Thanks in advance guys

Hi and welcome to SevenForums,
After reinstalling win-7 did it ever work ?

Sounds like the board is defective to me if not
Not sure if you have another card or not to test the pci-e slot ?
I'd forget about win-10 and concentrate on win-7 operation seeing as this is SevenForums

Hey thanks for your reply...

No it didn't work after installing 7, don't think it's the pci slot either as I tested it with my other card hd7970 and it worked fine?!

Hi,
Ouch we just entered the twilight zone then
Link to the exact 980 card you bought just for the record :/
Some have 2-6 pin some have 2-8 pin power connectors which does it have and what does the 7970 have ?

 

[AddRAM]

Are there any 6 pin power connections on the motherboard itself ?

 

[Richie10979]

Here's the card and both have 2 x 8pin power

Gigabyte NVIDIA GTX 980 WINDFORCE 3 OC Graphics Card - 4GB - GV-N980WF3OC-4GD - Scan.co.uk

Hi,
I messaged someone with a similar gpu as you have possibly he might have a tip to try
As long as you're using both connections I don't have a clue why it would not function

 

[Richie10979]

Bless thank you... Very much appreciated

No problem mate that is a wicked gpu
The only other wilder one is the water force :shock:

I think Tommy has that card.

His, Gigabyte Windforce GTX 980 G1

He has been AWOL lately, I think he`s at Tenforums

 

[ThrashZone]

Hi,
You can sign up and probably use the same user name and password unless it's already being used

Tried a CMOS clear, loading defaults in BIOS?

I don't recall seeing Tommy on TF.

Richie, try doing a clean install without the card connected. Use the on board graphics. Then go to device manager and uninstall the drivers for the on board graphics, it should tell you to restart. Don't restart, shut down. Then unplug the power, drain the residual, install the card, connect the power cables and connect the monitor to the card and restart. Windows should recognize new hardware. Have the driver ready and install it .

Just a thought.

Put what power supply is being used in (My System Specs). Their might be a problem there.

Jack, first post:

..two power supplys both 650w..

Would you still want PSU info?

 

[Layback Bear]

I'm suggesting that such information should be in (My System Specs) so it is readily available without going through all the post looking for it.
Exactly what power supply is being used, not just the wattage.
