Experiencing odd problems during startup.
Experiencing odd problems during startup.
Hello everyone, I need to reinstall my graphics card into a different PCIe slot every time I power on. Otherwise, it fails to boot into BIOS. This issue started yesterday and keeps occurring whenever I try to start now. The motherboard displays an error code AE, which according to the manual indicates "Boot to legacy OS." A few seconds later, the screen changes to A5, meaning "Issue reset during SCSI initialization." I looked up both solutions and found some that didn’t work for me. The steps I tried that didn’t help were: clearing CMOS, replacing RAM, and uninstalling the graphics card before reinserting it. At that point, I was just guessing whether the PCIE slot had a problem, so I installed it in another slot. Once I got back to the OS, everything worked fine. However, when I plugged it into a different slot afterward, it functioned normally. I suspect the problem might lie with my chassis. As shown in the attached photo, there seems to be a gap between the graphics card’s backplate and the chassis, which means I might need to bend the chassis to fit the screws. My guess is that when the screws are tight, the chassis could exert pressure on the card and try to pull it out from the slot, causing poor contact. Although I’m not sure, since the card still works when I change slots, it could be related to the chassis alignment. Here are my specifications: Motherboard: Aorus X399 Gaming 7 (BIOS version F12); CPU: Threadripper 1950x; RAM (before replacement): GSkill f4-3200c16q-64gtzsw; Graphics: MSI GTX1080Ti Gaming X 11G. Thanks for reading, and I hope this helps.
Ensure the GPU is securely attached to avoid shifting or disconnection. Verify that the motherboard is properly installed.
