user: I'm trying to install a new graphics card for my computer, but it doesn't get past POST with my new graphics card (motherboard doesn't even beep). Give me 5 troubleshooting steps I can try, what they do, and what I should expect from each.

assistant: Hardware problems can be frustrating. Here are 5 tips to troubleshoot issues with your new graphics card:  
1. Ensure it’s properly seated in the slot. PCIe slots can be finicky and hard to see depending on your case. Ensure the tab at the end of the slot that locks the card in place is fully raised. Try re-inserting the card if anything seems off.   
2. Ensure your power supply has enough capacity for your new card. Since your motherboard doesn’t seem to be posting at all, you may have a power issue. Ensure that your power supply has enough wattage to power your motherboard, processor, GPU, and all connected peripherals like disks. Try disconnecting any unneeded drives or accessories to see if the computer will power on. Remember, your power supply should have a little buffer of extra capacity for unexpected spikes in load. If you’re right at the limit, you may need to upgrade.  
3. Ensure the power cables are the correct cables for your power supply. Never mix cables between different brands of power supply — they make look the same, they may even fit in the same slot, but the pin arrangement may be different and cause you to fry your hardware.  
4. Try removing the card and starting the computer without it. We want to isolate the problem: is it the card, or is it the motherboard having an issue? If the computer is able to POST without the card, then the card is causing the problem. If not, it’s time to expand the search.  
5. Verify that all the power connections and cables to the motherboard are still properly attached. Oftentimes when installing a big accessory like a GPU you’ll have have to adjust the position of internal cables. Ensure that when you installed the card, you didn’t accidentally unplug something else. Double check that the wires connecting the case power button are still connected — sometimes it really is that simple!

user: When I removed the card, as you suggested in #4, the computer boot up. I also followed 1, 2, 3, and 5, but couldn't find anything wrong with the power cables or power supply. I then put the GPU back in, and the problem came back.

What should I do next?

assistant: If the computer boots up without the graphics card, but not with it, it's possible that the graphics card itself is faulty or there may be an issue with the PCIe slot. Here are a few steps you can try next:

1. Check the PCIe slot: Inspect the PCIe slot to make sure there are no visible physical damages, dust, or debris that could be interfering with the connection. Clean the slot with compressed air or a soft brush if necessary.

2. Try a different PCIe slot: If your motherboard has more than one PCIe slot, try installing the graphics card in a different slot to see if that resolves the issue.

3. Test the graphics card in a different system: If possible, test the graphics card in a different system to see if it works properly. If the card is still not working in the other system, then it is likely a faulty card and should be returned or replaced.

4. Check for BIOS settings: Check your motherboard manual to see if there are any BIOS settings related to PCIe or graphics cards that need to be configured correctly.

5. Update motherboard BIOS: Try updating your motherboard BIOS to the latest version, which may help address compatibility issues with the graphics card.

After trying these steps, test to see if the computer boots up with the graphics card installed. If it still does not work, it may be necessary to consult with a professional computer repair technician.
