I recently upgraded my graphics card from an AMD Radeon RX 580 to an Nvidia RTX 5060 Ti. After uninstalling the old drivers in safe mode using DDU, I installed the new card. When I powered on my PC, the CPU fan started, but I didn't get any display on my monitor. Instead, I'm hearing a half-second beep every 10-20 seconds. I don't think the PCI-E power connector is an issue since the GPU fans are running fine. I also checked my motherboard settings to ensure I'm on UEFI mode by testing my old card, which confirmed that I'm good there. My PSU is 620W and I'm using an MSI B450M Bazooka motherboard.

Check if there are any debug lights on your motherboard, they can be really helpful in diagnosing this kind of issue.
That beep every 10-20 seconds suggests your PC is trying to boot and failing. I'd recommend updating your BIOS since your 400-series motherboard has had many updates. After updating, reapply the XMP or DOCP profile for your RAM. Check that ReBAR or SAM is enabled, and ensure you're on full UEFI mode without CSM. Then try the new card again!
The power connector should be the same as your old card, right? Just double-check that the 6+2 connectors fit together tightly; they can be a bit tricky.
Is there no display even at BIOS? It might be that the card isn't seated properly. Also, those beeps are codes! Look up how many beeps you're hearing in your motherboard manual for guidance.
Make sure your PSU can handle the new GPU. Also, try resetting your CMOS battery on the motherboard and reseating your RAM.

Just wanted to let you know that I followed this advice and everything worked! Thank you so much!
