Yes, very common.

Okay, I will contact them in the morning. Thanks

Cannot* it seems certain characters are turning into ? And a box

If anyone out there could help, I would really appreciate it

Hi ASRock Forum,

I have a problem that I really can?™t fix and I really require your assistance.

I am currently on a ASRock x99 Extreme4/3.1

My original BIOS A version was P1.3 and I went into the BIOS to update it from P1.3 to P3.0 via the flash method (I downloaded the P3.0 instant flash version from your x99 Extreme4/3.1 support page). A successful message came up and when it asked me to press enter to restart, it restarted but then got stuck in a black screen (it wouldn?™t get to the POST screen with the ASRock logo, it just stays in a black screen like it cant post). I have tried everything after that point, clearing/removing the CMOS battery (left it out for 8 hours and did the jumper clearing (pin 2-3) ), going into BIOS B ( backup version is at P1.3) and trying to do the ?œSecure Backup UEFI?? When I attempt to do that, it says it will begin after I press OK, and then it reboots but now gets stuck in the ASRock post screen (with the options on the bottom right side - F2/DEL, F11, etc) and I have no keyboard input at that point.

My question is, how can I successfully downgrade the BIOS A?™s version to BIOS B?™s version? Do I need a new BIOS Chip so it would fix it? I have lots of pictures of my original BIOS state when it was working and all of the different issues I came across, which I can supply to you if it would help solve the issue.

Please help me. I have tried everything. I really need an expert?™s help.

Thank you
