When I put my GPU in I get no picture

When running off my motherboard I get a shoddy picture but when I put my GPU in and turn the PC on I get no signal on the screen. I tried downloading and installing the appropriate drivers from the Nvidia website but without the hardware I can't install them. Does anyone know how to fix this? Thanks

Clarification Request
Tell more.

Some HP's don't accept some cards. And then we have GPUs that need a power connection to work. Finally we have issues where the owner didn't connect the display to the new card.

GTX 980

I've got a GTX 980 with an Asus Z97-A, I've plugged it into the motherboard and PSU and also tried it with both things connected to my monitor many times

The 980 would require a big PSU.

I checked for comparability

I have got the 980 and PSU connected and checked on a few websites like pcpartpicker for example before buying all of my parts to make sure they were all compatible, and they are, besides the fans on the GPU and lights all turn on so I don't think it's a power problem, and I can't even get to bios with the GPU plugged in, the screen says no signal. Thanks for replying quickly it's appreciated Happy

I can't check for you

But there are folk that found the 980 to not boot on that board if the BIOS was older.

Next time, supply the BIOS and board revision and the full make/model of the PSU so I can do some basic checks. Also, you didn't write about the connection from GPU to PSU.

Alright so you would suggest maybe updating the bios to help run the 980? My power supply is an EVGA 550W 220-GS-0550-V1 R and I don't know how to get that info about the bios and motherboard, I'm new to most of these terms, also the connection from PSU to GPU is two 8 pin PCI-E connectors

While it met the spec

So, BIOS update?

Thats fine I'll have replaced it by then, so long story short you think a BIOS update would sort out the no signal problem?

Unless it's a dead GPU.

I shared my findings so you can read along. Nothing is a sure thing. But since others noted the issue, it's a high probability. In parting I don't like pushing PSUs this hard. It should boot fine but if it starts to BSOD under load or random reboots the PSU may be too close to the edge.

Alright thanks a lot, I'll try the update tomorrow, appreciate the help

Hi, I'm trying to update my bios using winflash like it says on the Asus website but it says 'Winflash does not support this BIOS update' any ideas?

Only ASUS should answer.

As a rule I never give bios update support since if I do one thing wrong or any misinterpretation and it can brick the board. This is for Asus to tell you what's up.

My bet is you don't have your exact board model (versions of the board) or got the Winflash for another board.
