I bought used motherboards and I can’t get either to post. One is an Asus B250 Mining Expert and the other is a ASRock H110 Pro BTC+.
I tried the ASRock first and I could not get a video signal from anything but there was a red light on the M.2 SSD (Crucial MX500). I thought the SSD might be incompatible so I pulled it from the board. My understanding is that I should be able to get to the UEFI without a drive. Is this correct?
I have tried both the video out on the board and a graphics card hooked up to the X16 slot.
I have also tried the ASUS, with the MOBO and CPU power and with a single graphics card int he X16 slot. again, nothing. The fans on the CPU cooler and the graphics card both start spinning on start-up.
Without a storage device, I should still be able to get to the BIOS right? I was planning on just running a linux srt up from a USB stick, but I can’t get anything to show up on the monitor. What else can I check.?
I did buy both of these used off two different people. Did they both sell me dead motherboards?
