GPU performance issues persist following PCIe X1 Wi-Fi card installation.
GPU performance issues persist following PCIe X1 Wi-Fi card installation.
I experienced frequent disconnections while using a USB Wi-Fi adapter. To resolve this, I bought an ASUS PCE-AC68 Wi-Fi card from Micro Center and installed it in one of my PCIe 1x slots. After turning on the PC, I saw a "No Signal" alert on the screen. I checked the hardware and found everything intact. I tried various settings and connections—different monitors, display ports, another PCIe slot, BIOS adjustments—but nothing worked. Eventually, I realized the integrated GPU was functioning properly. I adjusted the BIOS to prioritize the built-in GPU instead of the NVIDIA one. However, when I rebooted with the new settings and the NVIDIA GPU connected, the BIOS and Device Manager failed to recognize it. I attempted updates, reset the CMOS, and changed some PCIe BIOS parameters. Despite these efforts, the issue persists. Additional problems include the screen flickering between white and black, the BIOS resetting occasionally, and CPU fans running at full speed. In short, after installing a new Wi-Fi card in a PCIe slot, my NVIDIA GPU isn’t sending a signal and the BIOS can’t detect it. What’s causing this? Is there a solution or replacement I should consider?
It's usually tough to figure out what's wrong when you can't see the problem directly. There are many factors that might be involved, so I'd start by checking if the issue appears at the same time as you install the Wi-Fi card. If there were problems before, we can address them first—like replacing the CMOS battery. Then I'd clear out all unnecessary stuff from the PC, including extra drives, GPU, and new cards, to see if a clean boot works. If not, we strip everything down and rebuild. If it does work, adding the GPU might help. Keep going until we find the cause.
Thank you for your response. I will replace the CMOS battery. I tried launching the PC using just the requirements and my SSD, which contains the OS, but received the error "Reboot and Select proper Boot device." I plan to format both drives, remove everything carefully, verify all connections, and reinstall Windows with only the SSD installed. Concerning the sudden shutdown after removing parts like the Wi-Fi card or GPU, it appears to happen only once following such changes.
