New Member AMD Motherboard Thread

Hi Xaltar. Thanks for the help. Here is the post or my problem.

I have a B550 Taichi mobo. It wont post or give me an option to go to the bios. This is the second time it has happened to me. The first time it happened I was trying to boot from a linux usb. I had to go to the bios make it boot from the usb and disabled my other drives. I can't use F11 to get to the boot menu. That has never worked for me so I go to the bios to tell it what to boot from. The usb would not boot. So I restarted the computer without the usb and it would not give me the option to go to the bios. The screen stayed black. The debug codes ran till they went off and it would power off. Other times the debug stopped at A6 or is it Ab? And the power stayed on when it did that. It continued to do that so I started trying things like clearing the cmos and removing the battery, holding the power button the discharge everything, moving the dimms and trying only one and disconnecting everything, satas, usbs, M2. I don't know what I did but it came back to life. I hooked everything back up and it was fine. Till I tried to boot the usb again. Not the same one I made a new one. But it did it to me again and I can't get to the bios. I did the same troubleshooting and it didn't help. I have been down for a month now. I asked Tech support for help and wrote them nearly the same thing 3 weeks ago. The only response I have had was automatic email saying they got my message and a tech would get back to me. So I decided to try this forum while I am waiting for their reply. Any advice is appreciated...Cheers

I was considering trying to do a bios flash. Maybe it will detect the usb in the bios usb port. Would it be bad to flash the same bios again?
