Question Problem after a bios upgrade - B250M BAZOOKA

[shadowdev]

Hi guys!

I have PC meant to be a home server with the following specs:

CPU: I7 7gen
Motherboard: B250M BAZOOKA
RAM: Crucial DDR4-2133 2x8GB

And i was upgrading the bios version and after upgrading the screen went black.

After that the PC never turned on, no image, the fans start spinning and the CPU gets hot but the EZ Debug LED says that the CPU is in fault.

I have tried the ram sticks separately on different slots and still no image.

I have no disks connected but at least I should get image on the screen but simply I get a blank screen, I don't know what to do at this point.

What BIOS version were you on and what BIOS version were you trying to flash to? Have you tried clearing the CMOS? Disconnect from the wall and display, then remove the CMOS battery. Press and hold down the power button for 30secs to drain any residual power. Replace the CMOS battery after 30mins and then try and power back up.

You might want to get your hands on a CH341A BIOS programming toolkit and then reflash the BIOS using a donor platform/system/laptop since your motherboard doesn't have any form or option to recover your BIOS.

You can try and reseat the CPU and see if that helps. Following that you can drop the processor onto a known working, compatible motherboard with the right BIOS version and see if the issue persists.
