ASUS Z170-A, red LED near southbridge on and crashing on boot
This is a new build and I have windows 7 freshly installed. There are 3 main issues im having
- computer would get stuck and display a black screen after showing the ASUS logo and the red "Boot Device" LED below the southbridge would stay lit (normally the LED sequence would be CPU LED > RAM LED > PCIe LED > SB LED > then turn off and enter boot)
- computer would crash while trying to boot into win 7 and come back with a request to go into windows startup repair. using startup repair would also crash the machine
- the computer wouldn't recognize USB devices. i know win 7 doesn't have native support for USB 3, but the problem exists even when i plug it into the 2 USB 2.0 ports
- i cannot flash the BIOS anymore, any version i try to load comes back with the message "selected file is not a proper BIOS"
i searched online and found CSM (compatability support module) could be the problem, but i've tried all 3 modes (auto, enabled, disabled) and yielded similar results
i also tried reinstalling win 7 on the same SSD, thinking it might be a bad install, but the problems continue
is there any way to flash an older BIOS onto the board?
