Black Screen after GPU upgrade

[Laska]

Hey all, 

 

I've recently bought a used MSI RTX3070 Supreme X which when I was purchasing I was successfully able to play games etc on the buyers PC... happy days.

 

When I then plugged it into my PC I can see all the lights as normal, GPU lit up and so on however the screen remained black. I've already tried a bunch of this as per the below:

 

1. Using different monitor

2. Using different port on the GPU (HDMI & DisplayPort)

3. Use different PCI slot

4. Updating BIOS to the latest

 

 

The current spec is (try not to laugh to hard I'm on a "Had kids" kinda budget)

MB: Gigabyte Sniper M3

CPU: 3570K
RAM: GSkill 16GB DDR3

PSU: Corsair RM850i

GPU: ASUS 970 Strix

 

Any advice would be greatly appreciated.

Welcome to the forums!
What GPU did you have in it before?
Also, you should be aware that your CPU is a MASSIVE bottleneck here

Hi!

Previously I had Asus 970 Strix, still works now when I plugged it back in (Corrected the new GPU & added this to the header).

Yes, I am aware. I managed to overclock it to around 4.4GHz which I was surprised it can handle since that gen of intel was terrible for heat - Just waiting to pay off some debts before a fresh build hopefully at the end of the year

So unlikely to need a DDU, though that wouldn't hurt

And I assume that if you swap back in the 970 it works fine?
And I also assume you have no other PCIe slots occupied

And you of course swapped from the 2x6pin to 2x8pin pcie power connectors. Do try unplugging and replugging the power cables (both ends if you have fully modular PSU)

I'll give DDU a go, but yes if I put the 970 back in it works without issues.

Turns out DDU has resolved it! 

Thank you for the advice
