Hi,
I have a Taichi x399 which now refuses to boot (it was working OK), error code is 90 which doesn't show Dr Debug list.
I've tried removing/adding back memory, different GFX cards etc but the sucker will not boot, lots of other codes flip by on the LCD but it ends up at 90 and sits there!
I had recently upgraded to the 3.60 BIOS but everything had been running OK, the PC just crashed while unattended last night and now fails to start!
HELP :)
Thanks
HEADRAT

I don't seem to be able to edit my own post, weird!
I've also just tried to use the "Bios Flashback" to the bridge bios 2.3 and I just get a solid green light which means it didn't work, as per FAQ "If the LED light turns solid green, this means that the BIOS Flashback is not operating properly"

If the PC was running fine, suddenly crashed and never starts anymore it looks like a PSU issue from my point of view.
