Hello,

I purchased a Radeon RX 6600 for my system to replace a GTX 1050. When I install the card and boot up the computer, I'm stuck at the start screen. I can press delete to go to BIOS, but it just hangs and never actually gets to BIOS. I installed/reinstalled the GPU several times, and swapped the old GPU back in. The PC starts as it should with the old GPU, but I have the same problem with the 6600 each time.

I have a 550w  PSU which should be more than adequate, and and I have the PCIE power plugged into the GPU as it should be. The GPU fans turn on when I start the PC, so I know it has power. I've quadruple checked all connections and I'm sure that's not the issue.

I tried uninstalling the nvidia drivers and trying again, which did not work either.

My PC is a 2017 era Acer Aspire TC-780 desktop, with the acer motherboard.

I've looked and there are several BIOS updates I could do (https://www.acer.com/us-en/support?search=TC-780&filter=global_download&suggest=tc-780;2), I'm not at my computer right now but I think my BIOS version is R02.A2. Would an old BIOS cause this problem?

I'm just about out of ideas of how to get this card to work, and I thought this might be a good place to post this question. I appreciate any help or ideas!

It could be that your PC might not support UEFI/GOP boot and that's why it doesn't post. It also could be that there is a whitelist, but try a bios update first when you are able to.

I have sama gpu and sometimes while boot i listen 1 long beep and 3 shorts what means is a gpu failure however it runs normally past some seconds.

Adrenaline reverts to defaults. Weird.

Your old card was a PCIE gen3 card. I would look in BIOS to see what your PCIE lanes are set for. It is most likely set to gen 3 or auto if it even has that option. That being said there is no reason why your new card can't run with those settings. I agree with Dragokar. Try updating to the latest BIOS and go from there.

Having the same issue, did you ever resolve it? Please let me know. Thank you.

Possibly your PSU might be defective and not have enough power to run the new RX6600 GPU card.

Also try install the 6600 in another PCIe 3.0 slot if available to see if it boots up but I see your Acer PC only has one PCIex16 slot so you can't do that.

In BIOS do you have it set for UEFI or CSM Mode?

Try setting BIOS to first UEFI mode and then to CSM Mode (Legacy) to see if it boots up in either settings. You probably might need to do a CMOS CLEAR to reset the BIOS after changing settings and it doesn't boot up.

I see that your Acer PC uses an Intel APU. Connect your Monitor to the Motherboard's video output which uses the Intel IGPU and see if it boots up with the AMD GPU card installed and you have video output into Windows.

With the RX6600 installed what is the Beep codes that you hear?  Are any Motherboard Trouble LEDs lit up?

If you install the Nvidia GPU card again and it boots up into Windows download and run OCCT PSU Test and see if it passes and doesn't shut down. Check the PSU Outputs for proper 3.3/5.0/12 Vdc outputs.

NOTE: It is a possibility that the AMD RX6600 is not compatible with your OEM ACER Motherboard or PSU. I would open a ACER SUPPORT Ticket and ask them or open a thread at ACER COMMUNITY.

These are all good suggestions.  I think I would try the motherboard BIOS update first, while using the old video card (GTX 1050) that still works.
