Gigabyte Z390 Aorus Pro odd cold boot behaviour

milu316 · 24 Jan 2019 at 13:14

I currently have the board above and when booted from cold it powers on with no post for about 35 seconds then powers down then on again then boots normally. Is this normal Behaviour? I have just been on the phone to Gigabyte and they tried it with an Aorus master but it didn't behave the same.

is this normal or should I send it back? Everything else appears fine.

I have thus far tried multiple bios versions disabled all overclocking features but it always does this from a powered off mains state.

Can anyone shed any light on why it may be doing this?

No. I will try it when I get home tonight.

If it still does it what else could I try likewise if it stops doing it what would by my next step?

Hello,

That does not sound normal... Like the guys here have said try the minimum parts you need. Remove the VGA, use on board and 1 stick of memory and no drives. If it still does it then we can check it under RMA... if it stops when you have the minimum set up then slowly add the parts back on until you find out what is causing it.

If you do need to RMA let me know.

Well I stripped it back to basics reset the bios removed and reinserted a ram stick and its now fine. I wonder why a reset factory in the bios didnt work but a reset on the inside did, weird.

Ya. I did flick through the manual but couldn't find the jumper location so just pulled the battery.
