Can't enter bios on Supermicro mobo

[Reese]

Hello, 

 

New build, although I tested this board (Supermicro X8DTN+) a year ago with older CPUs and the same ram successfully. For the life of me I can not enter the bios or get past the boot screen. Here's some background: After finishing this build a couple days ago, I tried booting it up to get welcomed to the American megatrends post screen being stuck/frozen on "Initializing USB controllers..." With no response from hitting Del on my keyboard. After researching online for people with similar issues, I unplugged everything, took the GPU out and used the onboard VGA, took out all but 1 stick of RAM, swapped out the new CPUs with the older ones confirmed to be working, plugged in a ps/2 keyboard and reset the CMOS (took out battery and jumped the reset CMOS contact pads) to get nowhere. I have a new screen though, I'm pretty sure it's just a bios flash screen from me resetting the CMOS, image of new screen attached. Keyboard still not working, just flashes num/caps/scroll lock lights once upon booting.

So I'm here. Looking for some help/guidance as this is taking a while troubleshooting to get nowhere.

Thanks for looking or helping with my problem.

No response from keyboard at all - flashes once very quickly while booting and doesn't respond to any key once booted.

Yup, tried multiple sticks of RAM and reseated the PSU connections with no change

maybe the bios isn't compatible with the cpu try checking if it is

It is, I used this same CPU last year and it worked perfectly but now, with the system built it won't...

I was going to suggest PS2 keyboard and CMOS  but you already tried that, I just built a NAS with a SM mobo, so I'm curious the see what the problem is... It has been sitting for a year, in what conditions?

Here's another idea, if your case utilizes USB headers on the motherboard for usb portson OR a card reader on the case, try unplugging those cables from the motherboard.

Sitting on a plastic bag which the board came in on a table - nothing really touched it & I dusted it with a can of air before I put the board in... Although, after modding the case I put the board in it's possible an aluminum shaving got on the board... Will remove the board and check for that when I get home...

Unplugged all internal USB connections as well, to no avail...

Any help on this? Still trying to get this mobo working... Tried plugging in a boot drive with Windows on it with no success... Any help is appreciated.

 

Thank you

Bump. Still am looking for an answer to this. Thanks.
