My specs are below:

- Intel 17-2600 3.4Ghz LGA1155 CPU
- Gigabyte Z684-D3-B3 LGA1155 Motherboard
- 2x G- Skill F3-12800CL9D-8GbXL 8GB Kit DDR3, 1600Mhz RAM
- Gigabyte Eagle OC 8 GB RTX 3050
-PSU : Silverstone 750 watt strider good series

I have a bit of a weird issue. When I try plugging my RTX 3050 into PCIEX16 port it errors with long beep + 2 short beeps, and when I plug it into the PCIEX4 port it works fine.

I then tested my older 1050 TI graphics card on the PCIEX16 and it worked.

I have attached the error sound it makes

Is this;
the unit you're working with? How old is your PSU in your build?

the motherboard you're working with? If so, what BIOS version are you on?

it errors with long beep + 2 short beeps

Please stick to one thread unless you want spaghetti brains.

Yes that’s the correct motherboard and PSU that you attached.

My BIOS I have never updated so it’s whatever version that it came with.

My graphics card is this https://www.gigabyte.com/Graphics-Card/GV-N3050EAGLE-OC-8GD/sp#sp

And the older graphics card which is working in the PCIEX16 slot is this https://www.msi.com/Graphics-Card/GeForce-GTX-1050-Ti-GAMING-X-4G/Specification
