I built my computer 8 months ago. 6 months later, the mouse pointer started lagging so bad it was unusable. I tried some fixes but nothing really helped. The next day, my computer didn’t work. POST says it’s the graphics card. Okay, I got a new one. It arrived today and I put it in. Nothing has changed. The fans on the old one worked, so it had power. Did I misread my beeps or do something else wrong. I know enough to build a pc, but not enough to troubleshoot it.

This is my motherboard. It doesn’t have onboard graphics.

This is the old graphics card.

This is the new one.

Help!

As requested: 1 long beep, 3 short. No unusual flashing. It powers on fine and everything appears to be working inside, but it does the beeps and doesn’t show anything on the monitor. This is the power supply.

    It powers on fine. The only error is post that I can see because I can’t use the monitor to see anything else. There is no onboard graphics so the monitor isn’t usable.

    Power supply I put in the post, it’s 750W modular.

      Did you use two seperate PSU cables for each 8 pin on the GPU?

        It’s only got 1. I’d need a second power supply for a second cord. My very first pc build had interchangeable cords, but this power supply doesn’t. The fans on the cards work, so it’s definitely getting power.
