Outputs from a GPU function correctly across multiple CPUs, not just one.
Outputs from a GPU function correctly across multiple CPUs, not just one.
I'm experiencing a problem where my computer fails to detect GPU outputs until after entering the BIOS. My CPU lacks integrated graphics, so it can't reach the BIOS without one. To test, my cousin used a different CPU with built-in graphics. After installing his CPU, I followed the same steps—entered BIOS, saved changes, and noticed GPU recognition on startup. Once I swapped back to my original CPU, everything functioned properly. The main issue now is that CMOS resets each time I replace the CPU, requiring a BIOS reset before GPU detection. I've seen videos suggesting GPUs can auto-detect on first boot, but my experience shows it only works when integrated graphics are present. My hardware seems mostly functional, as long as the CPU matches the system requirements. I previously faced similar challenges about BIOS settings interfering with security features like Secure Boot. If you have any suggestions, let me know. Here’s a list of my components: https://pcpartpicker.com/list/YqHfcb
Set up a BIOS and store it properly. When using the display output, open the BIOS menu and verify the correct PCI slot is chosen. If placing your own CPU causes the BIOS to reset, simply restart the BIOS, then select the saved configuration. This should work if your motherboard supports saving BIOS settings. Dual BIOS configurations are now widely available.
You're experiencing issues with displaying the BIOS on your monitor due to the absence of integrated graphics in your CPU. The monitor lacks a display, preventing you from accessing BIOS settings. Additionally, using your own CPU without integrated graphics further complicates the process.
Have you explored booting from a thumb drive? Even a Windows install should load drivers and get you to the screen or attempt a live boot—Linux might be free to download. Your cousin could prepare a thumb drive if he has time. You might also consider replacing the CMOS battery, as it could be discharged. This is unlikely but possible; normally, the BIOS will check all available options. Try different cables, like DP or HDMI, and test them one by one. Cables often cause issues—switching them out and reinserting can help. Just remember the connections might need to be reversed. What was originally in the monitor could end up in the GPU, and vice versa.
I don't think the CMOS battery is having any problems because it worked with my cousin's CPU, though I'll check if necessary. I've started swapping HDMI and DP cables whenever I experiment to avoid assumptions, even though it's not harmful to try. Lastly, I haven't booted from a thumb drive yet, but I plan to do that soon.
